Description
BOLA reagent tubes with screw cap, 20 ml PFA, with PTFE screw cap are round-bottom laboratory tubes for sample handling, storage and reagent work. Manufactured from perfluoroalkoxy alkane (PFA) with a wall thickness of 1 mm, they are pore-free and closed with a PTFE screw cap for secure sealing. Dimensions comprise a nominal volume of 20 ml, height of 160 mm and outer diameter of 16 mm, giving a slender format that fits standard racks and heating blocks. The fluoropolymer body and PTFE closure support use with chemically demanding media while remaining transparent for visual checks. These reagent tubes from manufacturer Bohlender are supplied as a single piece with a net weight of 0,02 kg. The round-bottom geometry aids mixing and complete drainage, and the screw-cap design reduces evaporation and contamination risk during transport or intermediate storage. Suitable for sample preparation, digestion steps and general laboratory workflows where inert, non-porous tubing is preferred over glass.

Questions about BOLA Test Tubes, 20 ml PFA, with screw cap made of PTFE
What is this article?
BOLA Test Tubes, 20 ml PFA, with screw cap made of PTFE is the article on this page. Luminix Health distributes Bohlender 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.
