Description
Filtration/degassing unit for screw-thread bottle GL-45 is a glass filtration apparatus designed for filtration and degassing of solvents used in chromatography. It enables direct filtration into standard HPLC screw-thread bottles with GL-45 thread and accepts membrane filters of 47 mm and 50 mm diameter. A stopcock allows the filtration unit to be closed and supports subsequent degassing under vacuum. The supplied Duran bottle is coated and rated for vacuum as well as pressure service up to 1 bar, making the assembly suitable for routine solvent preparation in analytical laboratories. The complete set from manufacturer Landgraf HLL comprises the filtration head with clamp together with a 1000 ml coated bottle, ready for immediate connection to a vacuum source. Compact and purpose-built for HPLC workflows, the unit streamlines solvent clarification and degassing in one closed path, reducing transfer steps and contamination risk while remaining compatible with common laboratory membrane formats and GL-45 bottle systems.

Questions about Filtration/degassing unit for threaded bottle GL-45
What is this article?
Filtration/degassing unit for threaded bottle GL-45 is the article on this page. Luminix Health distributes Landgraf HLL 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.
