16mm Polyethylene Snap Caps, Lavender, for 16mm Glass and Evacuated Tubes — 1000/Case
The Globe Scientific 16mm Snap Caps provide a secure, color-coded closure for standard 16mm glass and evacuated tubes used in specimen handling, sample archiving, and routine sorting workflows. Molded from polyethylene in a distinct lavender hue, these caps snap firmly over tube rims to limit spills and aerosol release while keeping samples readily identifiable on the bench or in storage racks.

Frequently Asked Questions
What tube sizes do these snap caps fit?
These caps are designed for 16mm glass and 16mm evacuated tubes. Confirm your tube outer rim diameter is rated for 16mm closures before ordering to ensure a snug snap fit.
Are these caps sterile?
No. These polyethylene snap caps are supplied non-sterile and are intended for general specimen handling and storage rather than sterile sample preparation.
How many caps come in a case?
Both options are sold by the case of 1000 caps, with prices listed per case. The two SKUs let you match the specific Globe Scientific configuration your workflow requires.
Will these caps withstand organic solvents?
Polyethylene handles aqueous buffers, dilute acids and bases, and alcohols well, but resistance to acetonitrile is limited and aromatic or chlorinated solvents are not recommended. See the chemical resistance table above.
