Description
Closure caps for test tubes, Labocap 24/26, are aluminium laboratory closures intended for microbiological, bacteriological and biotechnological work. They primarily protect samples from external contamination while providing a sterilizable yet non-hermetic seal. Made from high-quality aluminium, each cap incorporates an inner spring of nickel-plated steel that holds the closure on the tube and permits the desired air exchange. These Labocap closures from manufacturer Labbox are autoclavable and temperature-resistant up to 140 °C, supporting repeated sterilization in culture and sample-handling routines. Supplied as a pack of 10 pieces with a net weight of 0,085 kg, the 24/26 size matches corresponding test-tube diameters used across microbiology and related life-science applications. The non-hermetic design balances contamination control with controlled aeration, which is often preferred where fully sealed conditions are neither required nor desirable. Robust aluminium construction and thermal resistance help maintain reliable performance through autoclave cycles in busy laboratory environments handling bacterial, biotechnological and general culture workflows.

Questions about Test tube caps, Labocap, 24/26, 10 pcs
What is this article?
Test tube caps, Labocap, 24/26, 10 pcs is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
