Tube, Vial Capper, Decappers

Apply and remove screw caps from your Thermo Scientific Matrix and Nunc tubes efficiently and ergonmically with these Thermo Scientific Capper and Decapper options. Choose from an 8-channel hand held model for low throughput needs or scale up to an automated model for higher throughput. All models tighten screw caps to the optimal torque to prevent sample loss.

Does it matter if caps are applied with optimal application torque?

Yes. Sample loss due to evaporation during long-term cryogenic storage is a common problem that can prove troublesome or even disastrous. Sample loss can alter the concentration or composition of the sample making it impossible to achieve reproducible results. This study demonstrates how the application torque applied to the tube closure during capping affects sample attrition following repeated thawing and freezing cycles.
