13mm Yellow Snap Cap Overview
The Globe Scientific 13mm Snap Cap (SKU 113143Y) is a polyethylene closure built for fast, secure sealing of common laboratory tubes. Designed in yellow for quick visual sorting, this cap fits 13mm glass tubes, 13mm evacuated tubes, and 12mm plastic test tubes. Color coding helps technicians separate sample batches and reduce handling errors on busy benches.
Snap-on installation speeds processing across high-volume workflows. Each cap presses firmly onto the tube rim and lifts off without tools, supporting repeat access during multi-step protocols. Polyethylene construction offers broad chemical compatibility for routine clinical and research samples.
Packaged in bags of 1000, this listing suits labs that close hundreds of tubes daily. Procurement teams can order single bags or scale to master cases for centralized stockrooms.

Laboratory Applications
Clinical and diagnostic labs use these snap caps to seal collection and aliquot tubes between processing steps. Yellow color marking lets staff group samples by patient, study arm, or assay type at a glance. Quick snap closure keeps throughput high during specimen accessioning and routine analysis.
Research and teaching settings rely on disposable PE caps for short-term sample storage and transport. Compatibility with 13mm glass, 13mm evacuated, and 12mm plastic tubes makes a single cap stock useful across mixed inventories. Single-use design reduces cross-contamination risk between batches.
