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, ATP, PCR Inhibitor.
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 applications.
O-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 tube.
Frosted cap writing pad for easy product marking and identification.
Color 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 500nm.
Tethered 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 available.
RCF range from 18,000 to 25,000 x g.
Temperature Range -80°C to +95°C. Short term storage in     -80°C, -20°C, dry ice and wet ice. Short term storage in vapor phase LN2 and suitable for a quick dip flash freeze in LN2.
Torque Manual/Hand Torque: Standard: 0.125 lbsf.in to 2.5 lbsf.in; Metric: 1.412 Ncm to 28.24 Ncm.
Torque Automated/Robotic Torque Standard: 1.312 lbsf.in to 2.5 lbsf.in; Metric: 14.83 Ncm to 28.24 Ncm.

Screw cap micro tubes and caps are not recommended for autoclave. Sterile options available.

Not intended to submerge and store in liquid phase LN2.
