This ensures even contact with the thermal cycler temperature block which delivers consistently superior well-to-well thermal transfer and rapid cycle times. Rapid and constistent thermal transfer is a critical factor in maximizing amplification yield.

The top surface of the tubes are designed such that the cap is easily guided into a positive and secure sealing position. The audible “SnapSeal®” gives positive assurance that the tubes are fully closed and will resist popping open during the thermal cycling and incubation stages. All UltraFlux® tubes and strips are designed to be compatible with all popular research brands of thermal cycler.
