Shipping policy

Stocked items are dispatched within 24 to 48 hours of order confirmation, Monday to Friday, excluding public holidays.

Items showing a longer lead time on the product page ship within the window stated there, typically 3 to 5 business days. The lead time is confirmed again on your quote before you approve it.

Orders confirmed after 2:00pm ET are treated as received the following business day.

If anything on your order will miss its stated window, we tell you before it is due, not after.

We ship to addresses in all fifty United States, including Alaska and Hawaii.

We do not ship internationally, and we cannot ship to freight forwarders.

We ship to commercial and institutional addresses. Some items cannot be delivered to a residential address.

Freight is charged at actual carrier cost and appears as a separate line on your quote before you approve it. We do not mark freight up.

Oversized, heavy and hazardous items are quoted individually, because their freight is not comparable to a standard parcel.

Because every order is quoted by hand, the number on your quote is the number you are invoiced. No shipping surcharges are added afterwards.

Orders ship by major national carriers. Tracking is emailed to you on dispatch.

Delivery estimates come from the carrier and are estimates, not guarantees. Once a parcel is with the carrier its progress is in their hands, though chasing them is our job, not yours.

Certain reagents and solvents are classified as hazardous for transport. These ship ground only, cannot travel by air, and cannot be expedited.

Hazardous classification is noted on the product page and confirmed on your quote.

Temperature-controlled items ship in validated packouts with pre-conditioned refrigerant, rated to hold 2 to 8 degrees Celsius for up to 48 hours on a summer profile.

Single-use temperature logging is available on request. Where a logger is included, its record is what we rely on to settle any question about the shipment.

Cold-chain orders are dispatched early in the week where possible, so nothing sits in a depot over a weekend.

Report any shortage, damage or wrong item within five business days of delivery and we replace or credit it in full.

We handle the carrier claim ourselves. You should not be spending your afternoon on a freight dispute.

Cold-chain items that arrive outside their temperature specification are treated as damaged and replaced.

If a parcel is confirmed lost by the carrier, we reship or credit, whichever you prefer.

Please check the delivery address before approving a quote. Once a parcel is with the carrier an address change may not be possible, and may incur a carrier fee.

Parcels returned to us as undeliverable because of an incorrect address can be reshipped at the cost of the return and the new shipment.
