Vacuum filters provided by Tech Seed Enterprise,

Overview

GVS EXTRACO Vacuum Filters are designed specifically for the filtration of culture media and organic solvents in research and industrial laboratories. It’s purpose-built with features designed to bring the highest levels of performance and purity to your research. A variety of membrane types and membrane areas are for choice that offer a wide applicability range for the separation and purification of most liquid samples to meet different laboratory needs.

What’s Special

✔ Designed hose connector can fit multiplicate hose diameters.
✔ Non-pyrogenic.
✔ Gamma irradiation sterilized.
✔ Lightweight and heavy wall construction.
✔ Large knurls on the reservoir bottle cap for easy screwing.
✔ Designed wide and easy access bottle mouth for efficiently and stably pouring out.
✔ Engraved graduation ensures the veracity.
✔ Ergonomically designed sidewalls and collar can simplify tightening, losing and adjustments.

Membrane Selection

Membrane	MCE	PES	PVDF	NY	CA
Type	Mixed Cellulose Ester	Polyethersulfone	Polyvinylidene Fluoride	Nylon	Cellulose Acetate
Characteristic	Composed of nitrocellulose and cellulose acetate; hydrophilic; low protein binding	Low protein binding; high flow rate; low extractables	Extremely low protein binding; available in hydrophilic and hydrophobic versions	Hydrophilic; broad chemical compatibility	Ultra-low protein binding; hydrophilic; uniform pore structure
Usage	Particle analysis, particle removal, biochemical analysis, HPLC sample preparation, aqueous solutions, and general culture media	Buffer filtration, culture media filtration, and pre-filtration	Non-aggressive aqueous solutions, mild organic solvents, and protein recovery applications	Filtration of aqueous and organic solvents	Biochemical analysis, protein-related applications, and aqueous solution filtration
Advantage	Good chemical compatibility; suitable for routine aqueous sample filtration	Fast flow rates; high throughput; ideal for biological samples	Minimal protein adsorption; ideal for maximizing protein recovery	Wide application range; excellent chemical resistance	High throughput; low adsorption; excellent dimensional stability
Limitation	Maximum operating temp. 40°C; Optimum pH range: 3~6; Not suitable for ethanol or alkaline solutions	Not recommended for strong organic solvents	Not recommended for aggressive chemical solutions	No specific limitations (depending on solvent compatibility)	Not recommended for harsh solvent environments
