Description
Sample bags with zip closure, W 300 × L 400 mm, PE are resealable laboratory bags fabricated from low-density polyethylene (LDPE) with a 50 µm film thickness. The larger 300 mm width by 400 mm length format accommodates bulkier solid or dry samples for collection, holding and transport in research, quality-control and routine laboratory workflows. An integrated zip closure enables repeated access and secure resealing, reducing exposure to dust and casual contamination during handling and short-term storage. Delivered in a pack of 100 pieces, the bags fit high-throughput sampling where single-use containment is preferred. Flexible LDPE construction from manufacturer Labbox balances low mass with practical toughness for everyday bench applications. Pack net weight is 1,243 kg. These minigrip-style polyethylene bags facilitate clear identification, organised storage and straightforward sample logistics without specialised equipment, meeting common laboratory packaging needs for non-critical sample management in analytical and industrial settings.

Questions about Zip-lock bags, 300x400 mm, polyethylene, 100 pcs
What is this article?
Zip-lock bags, 300x400 mm, polyethylene, 100 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 Matériel de laboratoire.
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.
