16mm Gray PE Snap Caps Overview
The Globe Scientific 16mm Snap Cap is a polyethylene closure engineered to fit standard 16mm vacuum tubes and test tubes. Molded in gray PE, each cap presses onto the tube rim with a secure snap fit. Labs use these closures to contain samples, limit evaporation, and reduce spill risk during handling and transport.
Polyethylene construction gives this cap flexibility and chemical resistance suited to routine laboratory work. The gray color supports visual coding across tube racks and sample sets. Technicians can apply and remove caps quickly by hand, which keeps high-volume workflows moving.
Sold in bags of 1000, this SKU supports clinical, research, and educational settings that consume closures at scale. Procurement teams can standardize on a single cap format and reorder by the case to keep benches stocked.

Laboratory Applications
Snap caps close 16mm vacuum tubes and test tubes during sample collection, storage, and transport. Clinical labs rely on them to seal specimens between draw and analysis. Research benches use them to cap reaction and dilution tubes, helping limit evaporation and contamination during short-term holds.
Color-coded gray caps assist organization in busy environments where many tubes share a rack. Educational labs choose PE closures for student work because they apply easily and resist common reagents. Diagnostic and biobanking workflows benefit from a consistent closure that staff can fit without specialized tools.

Frequently Asked Questions
What tubes do these caps fit?
These caps are designed for 16mm vacuum tubes and test tubes. Verify that your tube outer diameter matches the 16mm specification before ordering. Contact us if you need help confirming fit for a specific tube line.
What material are the caps made from?
They are molded from polyethylene (PE), a flexible plastic with broad chemical resistance used widely in laboratory closures. For sterility status or temperature ratings, contact us for specification before use in sensitive protocols.
How many caps come in each order?
One unit is a bag of 1000 caps. A master case contains 6 bags, totaling 6000 caps. Larger institutional orders can be quoted through LabSupplies.com.
