Sampling Instructions Cautions: • Do not store with food. • Before sampling, check the expiration date on the label on the outside of the pouch. Do not use after the last day of the month indicated. • SKC recommends using gloves when handling chemically treated media. • UMEx samplers are designed for single use only. Do NOT reuse UMEx samplers. 1. Open the aluminized pouch and remove the sampler. Do not discard the pouch; use it to send sampler to the laboratory.
