The TPE Capcluster-96 and Campmat-96 offer options for maintaining the integrity of tube contents at temperatures down to -80°C allowing to store samples confidently. The Micronic 96- well format push caps for externally threaded tubes are designed for long or short-term storage. TPE (the thermoplastic elastomer) has the necessary properties essential in sample storage and preservation. Its broad temperature range, excellent resistance to chemicals, high impact strength, and flexibility make them an ideal solution for the safe sealing of sample tubes stored in a 96-well format rack.
