Terms of service.

Who these terms are between

These terms are an agreement between Premier Analytical Sciences, LLC, a California limited liability company, trading as Premier Analytical Sciences (“the laboratory”, “we”), and the person or company commissioning the work (“you”). They apply from the moment you place an order or send material for testing, whichever happens first. If you accept them for a company, you are stating that you are entitled to bind it.

These terms take effect on 2026-09-25 and apply to every order placed on or after that date. For an order placed through this website, we record which version of these terms you accepted.

What the laboratory does

We analyze the material you send, on our own instruments, by the methods named on the certificate, and we report what we measured. That is the whole of the service. We do not certify products, approve companies, or advise on whether a material is suitable for any use, including human or veterinary use, or therapeutic, diagnostic, or clinical applications. Results should be interpreted by qualified professionals within the scope of the intended research.

What you send, and how it travels

Send sealed vials from the lot to be tested, in the container they shipped in, with the label claim exactly as printed and the name the certificate should carry as commissioning party. For a blend, give each compound in it and its claimed amount. You may also give each sample your own name for the material, such as a product code. It prints on the certificate beside the compound's chemical name and never replaces it, so it must be a name you are entitled to use. The order form calls a claimed amount the concentration: the amount of the compound in the whole vial, as the label states it. The order page states what to send.

Shipping to us is at your cost and your risk. A sample is in our custody from accessioning, the point at which it is photographed as received, given a lab number, and its condition recorded, and not before. If a package arrives damaged, short, or unidentifiable, we record the condition and tell you before any work starts.

What you are stating about the material

By sending material you state that:

• you may lawfully possess it and lawfully ship it to us;
• the label information you give us is what you believe it to be. We record it as stated by you and test the vial as received, and we do not change what you stated. If our identity analysis finds a different compound, the certificate says so beside your statement and reports the results for the compound we identified, and we tell you;
• it is not, and to your knowledge does not contain, a controlled substance under federal or California law, and you have told us in advance if it is hazardous or requires special handling; and
• you are not sending it to us to certify it for human or veterinary use, or for therapeutic, diagnostic, or clinical applications, and no result we return will represent it as fit for such uses.

Material we cannot handle

We do not accept controlled substances, and we hold no registration with the Drug Enforcement Administration to handle them. If a vial may contain one, because of its label, something you tell us, or something our analysis finds, we stop work on it, quarantine it, and open a documented hold under the name of the person who opened it. We tell you, and we contact the Drug Enforcement Administration or local law enforcement and hand the vial over as they direct. We do not return a held vial to you, we do not destroy it ourselves, and we report no result for it. We may give the authorities the order and custody records for that vial. If the concern turns out to be unfounded, we lift the hold, tell you, and carry on with the work. We may also refuse or stop work on a sample whose condition prevents testing. Where we refuse before testing, we say why.

Turnaround

Turnaround runs in business days from accessioning, not from the day you ship. The turnaround quoted for your panel is an estimate made in good faith, not a guarantee. If a run has to be repeated, or a sample arrives in a state that prevents testing, we tell you and the estimate restarts from that point.

Price and payment

The prices that apply are the ones quoted on your order. Where a test you have asked for is not yet priced, the order says so instead of showing a figure.

An order placed through this website is paid by card at the time you place it. The form totals the analyses, adds a card processing fee of 2.7% of that subtotal, printed as its own line before you pay and again on the checkout page, and hands you to Stripe Checkout to pay. Your card details go to Stripe and never reach us, as the privacy policy sets out. The order is recorded when you submit it, and no work begins on an order that has not been paid, unless a code from the laboratory covered it in full.

If the laboratory has given you a code, enter it on the form. The form still shows list prices; the reduced price, and the processing fee on it, appear on the checkout page. A code that covers the whole order places it with nothing to pay.

If the checkout fails, expires, or you close it, the order is not run and nothing is owed. Stripe closes an unpaid checkout after 24 hours, and our daily check then cancels the order once its checkout is more than 26 hours old, provided none of its samples have arrived. We do not send an email when this happens. Placing the order again starts a new order rather than resuming that one, so tell us if a duplicate appears and we will close the one you did not mean to place.

When card payment through this website is unavailable, the form composes the same order as an email for you to send from your own mail program. That order, and any order the laboratory keys in for you, is billed directly. We send an invoice or a card payment link when the order is placed. Payment is due before we release the certificate, by card or by another method we agree with you in writing, and we do not release a certificate on an unpaid order. Net payment terms are available only by written agreement with the laboratory. While an account has an unpaid balance, we may decline new orders and hold further releases. Cancellation and refunds are clause 16.

What a certificate covers

A certificate reports the analyses listed on it, for the vial we received, as it was on the date we tested it. It is not a statement about other vials, other lots, later production, or the material's suitability for any purpose. The standing wording frozen onto every certificate we release says it in the certificate's own words:

Results relate only to the specific samples tested. Reproduce only in full. This certificate reports only the analyses listed, and its results are intended for research use only — the material tested is not approved for human or veterinary use, or for therapeutic, diagnostic, or clinical applications. Results should be interpreted by qualified professionals within the scope of the intended research. Accuracy and reliability of results may be influenced by sample integrity, handling, and other experimental variables. An endotoxin screen is not a sterility claim.

Those clauses are stored inside the certificate rather than added at printing time, so a document always reproduces the terms it was released under, whatever this page says later.

No accreditation, no endorsement

Premier Analytical Sciences conducts its testing in accordance with ISO/IEC 17025 requirements; it is not an ISO/IEC 17025 accredited laboratory. Nothing we issue is a certification mark, an approval, or a regulatory clearance, and nothing on our documents or this site may be presented as one. We do not endorse any company or product named in the register. A record states what was measured, nothing more.

Release, revision, and withdrawal

A certificate is released when an authorized signer signs it. After that it cannot be edited by anyone, including us. A correction is issued as a revision under the same certificate number. The revision states why it was issued, the reason is shown on the register beside the record, and the earlier revision stays readable, marked superseded. A record that should no longer be relied on is withdrawn, which marks it with the reason rather than removing it. The register keeps superseded and withdrawn records visible on purpose, because a register that can only say yes is an advertisement.

Publication and the public register

Every released certificate has a permanent number and a stored document. Whether the record is listed, which means browsable and searchable by anyone, is your election, made when you order. If you choose public, the certificate is listed the moment it is released, whatever it says. If you choose private, it is released unlisted, and you may list it later, after you have seen the result, either with the publish button in the release email or by asking us. The button works once, for 180 days after it is sent, and whoever holds the email can use it.

An unlisted record does not appear when anyone browses or searches the register. It opens for anyone who has its exact number, which the certificate carries in print and in its QR code, on a page that says it is private. Release emails sent before September 2026 also carry a private link that opens it. Clause 12 says what that means for confidentiality.

Listing moves one way. A record that has been listed cannot be unlisted, by you or by us. A listed certificate names the commissioning party. An unlisted one may be anonymous, and making an anonymous record public requires issuing a revision that names you, because the document itself has to change. We do not remove a record from the register because the result was unwelcome.

Confidentiality

Your order details and contact information are kept confidential, except where publication is your election under clause 11, where clause 05 applies, or where the law requires disclosure. A certificate is different, because it exists to be shown. A listed certificate is public. An unlisted certificate is not published, but it is not secret. Anyone who has its exact number can open and download it, including the commissioning party's name unless you chose to withhold it, the lot, the results, and the vial photographs. Share the number only with people you want to be able to see the certificate. We do not sell client information. What we say publicly about a listed record is what the record itself shows. How data is handled in practice is set out in the privacy policy.

Samples after testing

Remaining material is not returned. It is held for two weeks after release, so the work can be re-examined or re-run if a result is questioned; when that period ends, the material is destroyed. Material that decays or degrades beyond testable condition before then is destroyed when that condition is recorded. Material held under clause 05 is handled under that clause instead. The accession photographs and the measured results stay part of the record permanently. Those are the evidence the certificate rests on, and they do not expire with the sample.

Using the certificate, and using our name

The certificate is yours. Reproduce it only in full: an extract of a certificate is not a certificate. You may state accurately that we tested a named lot and point to the record. You may not use our name or marks to suggest that we endorse, approve, or have certified a product, or that a tested lot says anything about an untested one. The methods, the register, and the software behind them remain ours.

If we get it wrong

If an analysis is wrong, tell us. Our obligation is to re-examine the work and, where it is warranted, to re-run the analysis or issue a revision, with both the original and the corrected record left readable. To raise a complaint, write to main@premieranalytical.comwithin 30 days of the certificate's release, naming the certificate and what you believe is wrong. We acknowledge it within two business days. A principal of the laboratory who took no part in the analysis reviews it, or an outside reviewer does if both principals took part, and we send you the outcome in writing within 15 business days or tell you why we need longer. A re-run needs remaining material, which we hold for two weeks after release under clause 13. After that, the review covers the recorded data, the method, and the photographs. A description of this process is available on request.

Our total liability for any claim arising from an analysis or its certificate is limited to the fees you paid for the analysis concerned. We are not liable for indirect or consequential loss, including lost profit, lost sales, recall costs, or loss of reputation, arising from a result or from its publication under clause 11. These limits do not apply to liability for fraud, willful injury, gross negligence, or violation of law, or to any other liability the law does not allow us to limit.

Cancellation and refunds

You may cancel an order at any time before its samples are accessioned, that is, before the vials are photographed, given a lab number, and their condition recorded, and no work starts. Cancelling then costs nothing: the full amount you paid, including the card processing fee added at checkout, is refunded. After accessioning the analysis is committed and cancellation is no longer open to you; the analysis is performed and reported, and whether its certificate is listed remains your election under clause 11. Once we have received a vial, an analysis we could not perform because the vial arrived untestable or was held under clause 05 is not refunded, and neither is the card processing fee on it.

If your samples had already shipped when you cancelled and they arrive anyway, they are not accessioned. Sending them back is at your cost, and we invoice the return shipping. Material you do not ask to have returned is destroyed after the same two-week period clause 13 sets.

Material that arrives in a condition that prevents testing, or that is quarantined under clause 05, is reported to you before any work is done. That report, and not a result, is what the order produced, and the vial itself is handled under clause 05 or clause 13.

A completed analysis is not refundable. You pay for the analysis, not for the result: a number you did not want is the work you commissioned, correctly done, and a register whose unwelcome results could be bought back would not be worth reading. Where the analysis itself is wrong, clause 15 is the remedy (re-examination, a re-run, or a revision) rather than a refund. A refund we do agree is paid back to the card that paid.

Changes to these terms

We may update these terms. The version in force is the one published on this page, with its effective date. A change applies to orders placed after it takes effect, and an order already placed stays under the version in force when it was placed. A change never alters a certificate that has already been released, which keeps the wording it was released under.

Governing law

These terms are governed by the law of the State of California, without regard to its rules on conflicts of law.

Before either of us starts a lawsuit about these terms or an analysis, we will give the other written notice of the dispute and try in good faith for 30 days to resolve it. After that, either of us may bring it in the state or federal courts in California, and in Los Angeles County where the law allows the parties to choose the county. Either of us may use small claims court for a claim within its limits. If any part of these terms cannot be enforced, the rest still applies.

Contacting the laboratory

Questions about these terms, or about a record we signed, go to the laboratory, not to the party who commissioned the work.

Your company's profile

A company may give us a profile to publish: its website, the location it states, a public contact email, and its logo. You can give them on the order form or by writing to main@premieranalytical.com. We hold them as a pending profile, and an authorized signer approves them before they appear. A published profile shows on your company's page and beside each of your listed certificates, never beside an unlisted one. The public contact email is the one you give us for that purpose, never the address on your orders.

You confirm that the details are accurate and that you may let us show the logo and link to the website. We show them as you supplied them, we do not verify them, and publishing them is not an endorsement. The web address of your company's page does not change once it is published. We remove a profile when you ask, and we may remove one at any time, and its page and logo stop showing within minutes. Removing a profile does not remove any listed certificate.
