13mm Snap Cap (White PE) Overview
The Globe Scientific 13mm Snap Cap (113146W) is a white polyethylene closure built to seal 13mm glass tubes, evacuated blood collection tubes, and 12mm plastic test tubes. Each cap snaps firmly onto the tube rim, giving technicians a fast, tool-free way to secure samples during handling, storage, and transport.
Molded from polyethylene, this cap resists cracking and provides a consistent fit across compatible tube formats. White coloring supports clear visual identification and labeling in busy specimen workflows. Technicians benefit from a uniform snap action that keeps closures predictable batch after batch.
Packaged in bags of 1,000, the 113146W suits routine clinical, research, and diagnostic labs that cap tubes in volume. Master cases bundle 20 bags for high-throughput facilities and central supply rooms.

Laboratory Applications
Clinical and diagnostic labs use these snap caps to close specimen tubes after collection or aliquoting, helping reduce evaporation and spillage during centrifugation prep, refrigerated storage, and sample transit. Their tool-free fit keeps cap-and-seal steps quick at high-volume benches.
Research teams apply the caps to glass and plastic tubes holding reagents, buffers, and biological samples. White color aids color-coded organization and supports surface marking for sample tracking across studies and shared storage racks.
