Globe Scientific 17mm Flange Plug Cap | Natural, Bag of 1000

Preventing evaporation and contamination in standard 15mL centrifuge tubes and 17mm test tubes requires a specialized, tight-fitting closure. The Globe Scientific 6263C Flange Plug Cap is meticulously engineered to provide an exceptionally secure seal for exactly these vessel formats. Manufactured from high-quality, chemical-resistant polyethylene (PE), these natural-colored plug caps feature an innovative double-seal design. The plug body inserts firmly into the inner diameter of the tube, while the overhanging flange simultaneously covers the tube's upper rim.

This dual-action sealing mechanism creates a highly dependable barrier against leaks during agitation, transport, or short-term storage. The pronounced flange also allows technicians to effortlessly push the cap in or pop it off with a single hand, significantly accelerating workflow during high-throughput fractionations or serial dilutions. Packaged economically in bags of 1,000, these caps are an indispensable consumable for any clinical or research facility utilizing 17mm outer-diameter tubes.

Features and Benefits

• Flanged Plug Design: The internal plug creates a friction fit against the tube wall, while the outer flange protects the tube rim—ensuring a leak-resistant double seal.

• Broad 17mm Compatibility: Precision-molded to fit tightly into standard 15mL centrifuge tubes, as well as any traditional 17x100mm or 17x120mm test tubes.

• One-Handed Operation: The protruding flange provides a convenient gripping surface, allowing staff to easily insert or remove the cap using just the thumb.

• Durable Polyethylene: Resists a wide range of laboratory chemicals, buffers, and solvents, ensuring the cap won't degrade or leach during sample storage.

• Economical Bulk Packaging: Supplied in large bags of 1,000 caps to support high-volume processing without constant reordering.

Frequently Asked Questions

Will these caps fit my 15mL conical centrifuge tubes?
Yes, standard 15mL centrifuge tubes have an outer diameter of 17mm. These flange caps are specifically designed to plug securely into that standard 17mm opening.

Are these caps autoclavable?
No, these caps are made of Polyethylene (PE) which will melt at standard autoclave temperatures. Do not autoclave these caps.

Can I write on these caps?
While the top surface is flat, space is limited due to the 17mm diameter. However, standard lab markers can be used to place a small dot or initial on the natural PE surface.
