Flange Plug Caps for Test Tubes. Flange Leak-Resistant Seal, Polyethylene

Keep tubes securely capped with flange plug caps. Molded from durable polyethylene, each cap features a flange design that presses firmly against the inner wall of the tube for a snug, leak-resistant seal. A convenient way to close and reopen tubes repeatedly without losing fit.

Flange Sealing Design

Flexible flanges grip the inside of the tube wall, helping the cap stay seated during storage, handling, and transport, and providing a more secure fit for a standard flange plug.

Wide Compatibility

Sized for selected size test tubes, the caps are also suited to centrifuge tubes and round cuvettes of matching diameter, making them a practical choice for general lab capping needs.

Easy-On, Easy-Off Use

The raised top and flexible flange body are designed for quick capping and uncapping by hand, a convenient option for repeated sample access during testing or aliquoting.
