Description
Centrifuge tubes with separate screw cap, brown polypropylene, self-standing stand ring, 50 ml support stable bench work without external racks. Manufactured from high-quality brown polypropylene on fully automated machines without human intervention, these tubes have an extremely robust wall that withstands centrifugal forces up to 6.000 RCF. They are autoclavable at 121 °C for 20 minutes; caps should remain open during autoclaving to avoid deformation of the tube body. The integrated stand ring keeps each tube upright on the laboratory bench at all times. Caps are moulded from polyethylene with broad grooves for secure grip and easy opening and closing, including when gloves are worn. Other technical characteristics match the conical-bottom centrifuge tube range from the same line, including leak-oriented cap design and practical handling features. Brown colouration suits light-sensitive samples and general laboratory use. These self-standing brown 50 ml polypropylene tubes from manufacturer ISOLAB Laborgeräte are offered with separate screw caps and packed in units of 50 pieces for everyday sample preparation, storage and centrifugation tasks.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about centrifuge tubes - amber - screw cap - P.P - 50 ml - skirted
What is this article?
centrifuge tubes - amber - screw cap - P.P - 50 ml - skirted is the article on this page. Luminix Health distributes ISOLAB 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.
