Select Color: T340BOSL CAP WITH 0-RING & LOOP, Blue


- Caps with silicone washer seal are made of polypropylene
- Free of RNase, DNase, Pyrogen, and DNA
- Available in nine colors

The cap is molded with a deep internal lip that fits snugly against the interior wall of the tube thus preventing the contents from coming in contact with the seal or threads, thereby reducing the chances of sample contamination. The cap's high profile facilitates manipulation especially in aseptic procedures. All tubes and closures are manufactured in a clean environment.

The looped cap remain attached to the tube in order to eliminate mix-ups and contamination.

Closures can be COLOR CODED by the use of T345 Series Colored Cap insert inserted on the top of the closure. This is accomplished without removing the cap.
