Screw cap natural, non-sterile (500 pcs.)

The APEX® Standard Screw Cap is a polypropylene flat-top cap with a silicone O-ring for a secure, leak-proof seal. Each screw cap has a height of 6.10mm and an outside diameter of 12.95mm. The caps can be used in a temperature range of -196°C to 121°C, making them suitable for cooking applications and frozen sample storage. However, they should not be submerged in liquid nitrogen. APEX® Standard Screw Caps are certified RNase, DNase, and DNA free. The screw caps are compatible with APEX® Screw Cap Microcentrifuge Tubes (Catalog Numbers: CP5910-CP5915). They feature internal threading, and a ¾ turn provides a tight and secure seal between the cap and the microcentrifuge tube. APEX® Standard Screw Caps are supplied non-sterile in natural color but are also available in a variety of other colors. They come in a pack of 500.
