Terms of sale

These terms govern purchases from Vitro Sciences LLC (“Vitro Sciences”, “we”). By placing an order, you agree to them and to our research use policy.

Eligibility and use

Products are sold for in-vitro laboratory research use only. By ordering, you confirm you are a qualified researcher or institution acquiring these materials for lawful research, and that you will handle, store, and dispose of them under applicable regulations. Our materials are not for human or veterinary use and are not drugs, foods, cosmetics, supplements, or medical devices.

The attestation you make at checkout is what we rely on. We do not verify credentials before an order ships, which is why the attestation, and the consequences of making it falsely, sit in these terms rather than in a form.

Age requirement

You must be 18 or older to buy from this site, and placing an order confirms that you are. Where we have reason to believe a buyer is under 18, we cancel the order and return the money. On the crypto rail that return is a manual refund, sent the way the crypto payment section below describes.

Orders, pricing, and payment

Prices are listed per vial in US dollars and may change. The price that applies is the one shown when you place the order; shipping is charged separately and shown before you confirm.

An order is an offer to buy, not a concluded sale. We accept it by confirming payment and dispatching, and until then we may decline or cancel it — for suspected misuse, for stock we cannot supply, or for a pricing error.

No payment method on this site charges a card. The two rails that settle money — crypto and Venmo — each differ from a card payment in ways worth reading before you pay, and the sections below set out how each one behaves.

Payment — crypto and stablecoin

Crypto and stablecoin payments settle through a payment system we host and run ourselves. Checkout sends you to its invoice page to pay. Invoices are denominated in US dollars. The asset amount is calculated when the invoice is created and is fixed for the life of that invoice. Changing your cart afterwards does not change the invoice; it means a new one.

Settlement is final and cannot be reversed. There is no chargeback, no network-level dispute process, and no party who can pull a confirmed on-chain payment back — not you, not us, and not the network. Where something is wrong with an order, the remedy is a refund we send, described below. It is not a reversal of what you sent.

Every invoice has a payment window, and the invoice page shows the countdown. We do not print the length of that window here: it is set per environment, so any figure in this document would be wrong somewhere. When the window closes the invoice is expired and no order comes from it. The invoice page does not send you back to us when that happens — it returns you only on a payment, so an expired invoice simply leaves you on its invoice page. Your cart survives, so returning to checkout starts a fresh payment.

A partial payment does not create an order. Sending less than the invoice amount leaves the invoice unsettled rather than completing it at the lower figure, and it may stay that way: an invoice that has taken a partial payment is not counted here as settled, and topping it up does not reliably clear that on its own. So do two things. Send the remaining balance to the same address before the countdown ends, and email orders@vitrosciences.com with the invoice and both transactions, so a person can check it and release the order. If the window closes first, the invoice is expired and what you sent sits outside any order — write to the same address with the invoice and the transaction, and we will apply it to a new order or refund it by hand.

An overpayment does not hold up your order. Sending more than the invoice amount settles it, and the order proceeds as normal — we do not withhold goods you have more than paid for. The excess is not credited or returned automatically. Email the same address and we will refund it by hand.

Refunds are sent manually, on-chain, by a person. There is no automated refund path in this system and that is deliberate, not an omission. We refund the US-dollar value of the invoice rather than the asset amount you sent, so a move in the asset price between payment and refund falls to you in either direction. We send to the address the payment came from unless we agree a different one with you first.

Returning to this site from the invoice page is not confirmation. You are sent back as soon as your transaction has been seen, which is before the network has confirmed it, and a transaction that has only been seen is not counted here as money received. Your order is accepted when the payment confirms, and the confirmation email is what tells you it has. The page you land on says which of the two you are looking at.

Canceling an order does not switch off an invoice that already exists. It stays payable. If you decide not to go through with a crypto payment, close the invoice page and send nothing — funds paid against an abandoned invoice have to be traced and refunded by hand.

Payment — Venmo

A Venmo payment link prepares a transfer. It does not confirm one. There is no Venmo integration behind this site, so nothing tells us automatically that you have paid.

Your order is placed and held before you pay, and it stays pending until the transfer is reconciled by hand against our Venmo activity and we email you. Leave the payment note as we generate it: it carries your order reference, and it is what a person matches your payment against. A payment sent without it takes much longer to find. If you have sent one and heard nothing, email orders@vitrosciences.com with your order number and the date and amount you sent, and we will match it up.

We hold an unpaid order for a limited number of days and then release it. Your order’s payment page on this site shows how long is left, and tells you if the order has already gone. A raw Venmo link cannot be revoked, so one saved from an old email will still open a payment screen long after the order behind it is gone — pay from your order’s payment page on this site, not from a saved link. Money sent against a released order has to be refunded by hand.

A Venmo transfer between people is not a protected purchase. Purchase protection does not apply to it, so there is no chargeback on this rail either, and any refund is sent by us, by hand.

Risk of loss and title

Title and risk of loss pass to you when we hand the parcel to the carrier. What happens in transit is outside our control, which is not the same as leaving you without recourse: our shipping and returns policy sets out what we do about a parcel that arrives damaged, arrives short, or does not arrive.

No medical claims

Nothing we sell or publish is intended to diagnose, treat, cure, or prevent any disease, and nothing on this site is medical guidance or a dosing recommendation. We do not provide administration instructions or human-use guidance.

Warranties and liability

Every lot ships with a Certificate of Analysis, and the COA for the lot you receive is the specification we warrant. We warrant that the material matches the identity and purity that COA reports, and you can look up any lot by its number at /verify. That is the extent of the warranty. We give no other warranty, express or implied, and to the extent the law permits we disclaim the implied warranties of merchantability and fitness for a particular purpose — a purpose we do not know and cannot assess for a research material. Where a lot does not match its COA, tell us and we will replace it or refund it. Our shipping and returns policy sets out how to report a defect and the window for doing so.

Our liability for an order is limited to what you paid for it. We are not liable for lost work, lost time, or other indirect losses, and we are not liable for use of the materials outside their research context. Nothing here limits a liability that the law does not allow us to limit.

Use of this site

The catalog copy, product photography and renders, the Learn articles, and the Certificates of Analysis published here are ours. Read them, cite them, and pass them to a colleague — that is what they are for. Do not republish them as your own, and do not attach a COA to material we did not supply: a COA identifies one lot, and separating it from that lot misleads whoever reads it next.

Automated bulk collection of the catalog or the lot documents is not permitted, nor is any attempt to reach accounts, orders, or documents that are not yours, to probe or disrupt the site, or to place orders you do not intend to pay for. We may block access for any of these without notice.

Account termination

We may close your account, decline an order, and decline future orders where these terms or the research use policy are breached, where we have reason to believe material is being bought for a purpose other than laboratory research, or where a payment cannot be reconciled. We may do so without prior notice and without stating a reason.

Closing an account does not undo an order already shipped, does not reverse a settled crypto payment, and does not release you from what you owe. A refund we owe you is still sent, by the process described above.

Indemnification

You agree to indemnify Vitro Sciences LLC against claims, losses, and costs, including reasonable legal fees, arising from your handling, storage, transfer, or disposal of material bought from us, from your breach of these terms or the research use policy, and from any human or veterinary use of the material, which these terms prohibit. This obligation outlives the closing of your account.

Dispute resolution

Email hello@vitrosciences.com before filing anything, with your order number and what went wrong. Most problems on either payment rail are reconciliation problems, and a person reading the invoice or the Venmo note settles them faster than a claim does.

If that does not resolve it, claims are brought in the venue named under Governing law below. These terms do not require arbitration and do not waive any right you have to bring a claim in your own name.

Force majeure

We are not liable for delay or failure caused by something outside our reasonable control: carrier or customs disruption, supplier failure, network congestion or an outage at a payment provider, natural disaster, or government action. Where such a delay makes an order impractical to fulfill, we cancel and refund it rather than hold it open indefinitely.

Changes to these terms

We revise these terms from time to time. The version that applies to your order is the one published when you placed it, and the date this document was last revised is shown at the top of this page. A substantive change gets a new date — we do not edit the wording and leave the date alone. Ordering after a revision means you accept the current version.

Notices

Formal notice under these terms — a claim, a termination, or anything else these terms require in writing — is given by email to hello@vitrosciences.com and by post to [to be confirmed before launch]. Email counts from the day it is sent; post counts three business days after it is sent. We write to you at the email address on your order.
