Description
Bottle adapter for LF3a/5a is a dedicated laboratory accessory that connects filtration apparatus models LF3a and LF5a to receiving bottles in vacuum filtration workflows. This component forms part of Witt-type filtration systems and enables secure bottle coupling during sample collection under reduced pressure. Supplied as a single piece with a net weight of 1 kg, the adapter supports stable mounting of compatible bottles within modular vacuum filtration equipment. It is intended for routine analytical and preparative filtration tasks where reliable bottle interfaces are required. Available from manufacturer Witeg, the bottle adapter integrates into existing LF3a and LF5a setups without altering the core filtration path. Its design focuses on mechanical compatibility and ease of assembly, making it suitable as a replacement or expansion part for laboratory vacuum filtration stations. The unit is used in research, quality-control and general laboratory environments that rely on Witt filtration apparatus configurations. Packaged as 1 pc, it provides a practical hardware solution for maintaining consistent bottle connections during vacuum-assisted sample processing.

Questions about Bottle adapter for LF3a/5a
What is this article?
Bottle adapter for LF3a/5a is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Plastic bottles (narrow & wide mouth), inside Bottles & containers, in Labware.
A plastic bottle is polyethylene, polypropylene or a fluoropolymer, narrow-mouth for pouring or wide-mouth for powders. It is the choice when the bottle must not shatter, and it is the wrong choice for solvents that swell the plastic.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
