Description
BOLA lid 5 ml PTFE with centring boss is a small laboratory cover designed to close matching PTFE vessels while keeping the lid aligned during handling. The lid has an outer diameter of 27 mm and incorporates a centring boss that seats the cover securely on the vessel rim. Made entirely from polytetrafluoroethylene (PTFE), it provides the chemical inertness expected for contact with aggressive reagents, solvents and sensitive samples. The 5 ml designation identifies the intended vessel size class, making the lid a practical spare or replacement part in micro-scale sample preparation, digestion or storage setups. Net weight is 0,004 kg per lid, and the product is supplied as a pack of two pieces. This BOLA PTFE lid from manufacturer Bohlender offers a simple, chemically resistant closure solution for compact laboratory vessels where metal or elastomer components are undesirable.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about BOLA Lids, 5 ml PTFE, tight-closing
What is this article?
BOLA Lids, 5 ml PTFE, tight-closing is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Lids & seals, inside Stoppers, caps & closures, in Labware.
Lids and seals are the covers of dishes, jars and tanks: a snap lid, a sealing film, a gasket. The seal is doing the work. A lid that only rests on the rim does not contain a volatile liquid.
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.
