16mm Red Snap Cap Overview
The Globe Scientific 16mm Red Snap Cap (SKU 113141R) is a polyethylene (PE) closure built for 16mm vacuum and test tubes. Each cap snaps firmly over the tube rim to contain samples during handling, transport, and short-term storage. Red coloring supports quick visual sorting and sample identification at the bench.
Polyethylene construction keeps these caps flexible and chemically resistant for routine laboratory use. Technicians get a secure, repeatable fit across standard 16mm tube formats, reducing leaks and cross-contamination risk during workflow steps. Snap-on design speeds capping versus threaded alternatives.
Bulk packaging makes this part practical for high-volume labs. Bags of 1000 caps streamline restocking, while master cases hold 6000 caps for centralized procurement across multiple departments.

Laboratory Applications
Snap caps in this 16mm format close vacuum and test tubes used across clinical, research, and quality-control settings. Phlebotomy stations, sample aliquoting, and specimen prep all rely on quick closures that seat without threading. Red coding helps teams flag specific assay types or batches at a glance.
Polyethylene caps suit aqueous samples, buffers, and general specimen handling where a flexible, chemically tolerant closure is needed. Labs running high tube throughput use bagged bulk caps to keep capping stations stocked through routine batch processing.
Ordering & Bulk Pricing
