Screw Cap Microcentrifuge Tube Caps Design

• 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
