16mm Red Snap Caps for Glass & Evacuated Tubes Overview
The Globe Scientific 16mm Red Snap Cap (113148R) is a polyethylene closure designed to fit 16mm glass tubes and evacuated tubes. Molded for a secure snap fit, each cap helps contain samples during handling, storage, and transport. The red color supports quick visual sorting across busy benches and racks.
Made from polyethylene (PE), this cap pairs flexibility with consistent dimensional control. Snap closures press on by hand, eliminating threading and speeding up batch processing. Labs that fill and seal tubes in volume benefit from a closure that seats reliably without specialized tooling.
Each bag holds 1,000 caps, and a master case ships 10 bags for a total of 10,000 caps. High-throughput facilities can standardize on a single closure across phlebotomy, clinical, and general sample-handling workflows.

Laboratory Applications
These snap caps close 16mm glass and evacuated tubes used across clinical, research, and quality-control settings. Phlebotomy and specimen-collection workflows rely on color-coded closures to keep samples organized and contained before processing. Red caps stand out in mixed racks, helping technicians sort tube sets at a glance.
Polyethylene construction suits general sample storage, short-term refrigeration, and benchtop handling. Teams running repetitive fill-and-cap steps gain speed from a tool-free snap closure. Standardizing on one cap size simplifies inventory for labs that maintain a single 16mm tube format.
