Description
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.
Screw Cap Microcentrifuge Tube Caps Design
- Screw caps with O-rings guard against leakage by forming a positive seal against the rim of the tube
- Tethered screw 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
- O-ring is manufactured from durable ethylene polypropylene dimonomere compound
Highest Quality
- Certified free of RNase, DNase, DNA and pyrogens
Color/Packaging Options
- Standard Screw Cap Color options are: Blue, Green, Orange, Red, Yellow and Mixed to aid with visual identification of samples
- Tethered screw cap with O-ring: Natural
