Lyophilised powders are stable at room temperature for short periods, such as in transit, but should be kept refrigerated and away from light for long-term storage.

Reconstituted material must be kept refrigerated. Avoid repeated freeze-thaw cycles, and follow your laboratory's own handling protocols.

We recommend moving products into refrigerated storage as soon as they arrive. Short periods at room temperature during delivery do not affect lyophilised material.

Unopened items in their original packaging may be returned within 30 days of delivery.
