Handling & storage

Three things to get right.

01

Store cool and dry

Sealed bottle, away from heat and light. Keep the desiccant in.

02

Keep the seal until use

Tamper-evident seal intact means the count and contents match the batch.

03

Log the batch

The batch ID is on the label and the certificate. Record it with your research notes so results trace back to the paperwork.

FOR LABORATORY AND RESEARCH PURPOSES ONLY. NOT FOR HUMAN CONSUMPTION.
