.5 ml Screw Cap Centrifuge Tube, Sterile

Screw Cap graduated Micro-Centrifuge Tubes have an Internal Sealing Ring that sandwiches the top of the tube to provide a positive seal to prevent liquid bypass. Continuous Threads require only a 1 1/4 turn to tighten while the nitrile o-ring provides exceptional chemical resistance while further enhancing the integrity of the seal.
Polypropylene caps and tubes are fully autoclavable. Caps for Micro-Centrifuge Tubes are available in a nitrile o-ring or molded in seal ring. The nitrile o-ring caps provide exceptional chemical resistance while further enhancing the integrity of the seal and are compatible with Sarstedt and Porex.
All tubes tolerate centrifugal forces up to 18,000 RCF.
These tubes are available in a variety sizes and cap colors to fit your personal needs.
All tubes have a temp range of -40ºC to 121ºC.
*Polypropylene is not recommended for use with Phenol Chloroform. Low temperature storage, multiple spin cycles or organic solvents can affect maximum force. Run a test before using.
