Description
Prevent leakage under demanding conditions with these screw-cap microcentrifuge tube caps with o-rings, which are optimized for secure, short-term storage in low temperatures.
Prevent leakage under demanding conditions with Thermo Scientific Screw Cap Microcentrifuge Tube Caps feature O-Rings to form a secure seal. Optimized for secure, short-term storage in low temperatures, these non-autoclavable screw caps are available in a variety of colors and adapted to your scientific experiments.
Non-Sterile is free of Rnase/Dnase, Human and Mouse DNA, Pyrogen & Endotoxin
Sterile E-Beam is free of Rnase/Dnase, Human and Mouse DNA, Pyrogen, Endotoxin, ATP, PCR Inhibitor
100% virgin polypropylene resin specifically selected for high clarity and biologic applicationsO-ring design, thickness and material selection have been optimized to provide protective features for maximum sealing ability, biologic interaction and temperature capability. The black colored O-ring is made from EPDM Knurled caps improve grip when opening and closing tubeFrosted cap writing pad for easy product marking and identificationColor caps offered in multiple color options ideal for separating, coding and tracking samples. Amber colored caps ideal for UV protection of 1.22% transmittance between 220 and 500nmTethered caps remain attached to the sample tube but can rotate completely for convenience–the tethered screw cap is the solution when it is important to maintain the same cap with the same tube. Non-tethered caps availableRCF range from 18,000 to 25,000 x gTemperature Range -80°C to +95°C. Short term storage in -80°C, -20°C, dry ice and wet ice.
