Pure-Pass sealing mats protect wells from leaks, contamination, and evaporation during sampling and storage. Pure-Pass sealing mats are available in clean room molded EVA and a specially processed low bleed, low-extractable silicone to reduce sticking and a pre-slit version is available for easier piercing and sample withdrawal.

All mats are for 96 well plates with 7 mm diameter wells. Excellent dimensional conformance with ANSI/SLAS ensures enhanced registration with the plate for ease of application. Each mat has an alphanumeric grid reference.
