Screw Cap Microcentrifuge Tube Design
- Tubes are designed with conical bottoms allowing for more complete sample retrieval
- 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 conveniencedash (em)the tethered screw cap is the solution when it is important to maintain the same cap with the same tube
