13mm Blue Snap Cap (113143B) Overview
The Globe Scientific 13mm Blue Snap Cap (113143B) is a polyethylene closure engineered to seal 13mm glass tubes, 13mm evacuated tubes, and 12mm plastic test tubes. Its snap-fit design lets technicians cap and uncap quickly without threading, supporting fast sample handling across high-throughput workflows.
Molded from polyethylene (PE), this cap delivers a flexible, secure fit that holds tubes closed during transport and storage. Blue coloring aids visual sorting, so labs running color-coded protocols can distinguish sample sets at a glance. Each bag holds 1000 caps for consistent resupply.
Procurement teams stocking phlebotomy, clinical, or general-purpose tube programs can standardize on this single SKU across multiple compatible tube diameters. Bulk case packaging reduces reorder frequency and supports predictable inventory planning.

Laboratory Applications
Snap caps like this one close sample tubes throughout clinical, diagnostic, and research settings. Technicians use them to seal blood collection tubes, reagent aliquots, and prepared samples ahead of centrifugation, refrigeration, or transport. Quick snap-on application speeds batch processing where many tubes must be closed in sequence.
Color-coded closures support sample organization and chain-of-custody protocols. Blue caps can mark a specific assay, patient group, or processing stage, helping staff sort racks without rereading labels. Broad compatibility across 13mm glass, 13mm evacuated, and 12mm plastic tubes lets a lab consolidate closures for several tube formats.
