Terms of service

Eligibility

You must be at least 21 years old and purchasing on behalf of a qualified research setting. Orders that appear intended for human consumption are cancelled and refunded.

The monthly $1 pick

Each account may apply one $1 pick per calendar month, on any in-stock catalog item, accompanied by at least one full-price item in the same order. Picks reset at 00:00 UTC on the first of each month and do not accumulate. We may limit or withdraw the offer where abuse is evident.

Pricing and availability

Prices and stock are subject to change without notice. Where a lot sells out after an order is placed, we contact you to substitute an equivalent lot or refund.

Limitation of liability

Our liability for any claim is limited to the purchase price of the material concerned. You assume full responsibility for the handling, storage and use of everything supplied.
