Globe Scientific Snap Caps (12/13mm, Red PE) Overview
Globe Scientific Snap Caps in 12/13mm red polyethylene seal standard vacuum tubes and test tubes with a simple push fit. Each cap is molded from polyethylene (PE), a flexible material that grips the tube rim and releases without tools. Red coloring supports fast visual sorting at the bench.
Designed for 12mm and 13mm diameter tubes, these caps fit the most common small-bore tube formats used in clinical and research labs. Snap-on closures speed up batch capping during sample collection and storage workflows.
Supplied by LabSupplies.com in high-count bags, this SKU suits facilities that consume closures in volume and need consistent fit across racks of tubes.

Laboratory Applications
Snap caps close tubes used in blood collection, sample aliquoting, and short-term specimen storage. Technicians cap filled tubes quickly during high-throughput processing, while the red color helps separate one sample group from another across a rack.
Research and clinical teams rely on PE closures to limit evaporation and contamination between handling steps. These caps fit 12/13mm tubes used in centrifuge runs, transport, and refrigerated storage, supporting traceable sample management.
