Description
Bottle thread adapter GL 32 to GL 25, PP is a polypropylene thread adapter that converts a GL 32 bottle neck to a GL 25 connection. This compact laboratory accessory enables secure coupling between bottles and closures, tubing or other labware components that use differing GL thread standards. Manufactured from durable PP, the adapter supports routine handling of aqueous solutions, buffers and common laboratory solvents in research, quality-control and production environments. The single-piece design ensures a reliable mechanical fit while remaining lightweight for easy installation and removal. With a net weight of 0,007 kg and gross weight of 0,008 kg, the unit occupies minimal storage space (packaging volume 0,001 m³). Supplied as one piece, the adapter originates from Germany and is offered by manufacturer Eppendorf as part of its range of bottle-thread accessories. Ideal for standardising bottle interfaces across mixed glassware inventories, it simplifies workflow when switching between vessels of different thread sizes without the need for intermediate transfer steps. The plain PP construction provides chemical resistance suitable for everyday laboratory use and facilitates straightforward cleaning between applications.
This article is part of Laboratory glass bottles, in Bottles & containers.

Questions about Bottle thread adapter GL32=> GL25,PP
What is this article?
Bottle thread adapter GL32=> GL25,PP is the article on this page. Luminix Health distributes Eppendorf for laboratory use. It sits in Rotor adapters & accessories, inside Centrifuges, in Lab instruments.
An adapter lets a rotor spun for large tubes accept smaller ones. The adapter has to be the one for that rotor, and the tubes have to be supported at the shoulder the adapter was designed for. A stack of the wrong inserts is an unbalanced load.
A centrifuge separates by density. The rotor spins the sample and the force is reported as a multiple of gravity, not as a raw speed, because the same revolutions per minute are a different force at a different radius. A microcentrifuge takes small tubes. A benchtop or floor model takes larger rotors. The tube, the adapter and the rotor have to be the combination the manufacturer rated. An unbalanced load is how centrifuges fail. Measurement of the related quantities sits with the BIPM.
