Glass Solvent filter and stainless steel filtration manifolds are mainly used in high performance liquid chromatography mobile phase filtration, particle analysis and microbial contamination detection.It is a kind of chemical laboratory common used consumables and equipment.
Selection of high-quality borosilicate glass or sanitary grade stainless steel for the material ,this can be used for filtration or analysis of various aqueous, organic and corrosive liquids, and can be hot-pressing disinfection.Our filtration apparatus offers ex-work price and high quality for your choice.

In using and after using them,please pay attention to the following points:
1, The solvent filter is fragile especially glass material, must not move the whole set together, in particular, can not hold the clip moving;
2, Filter membrane selection :To select qualified products, substandard will be dissolved into impurities, can be used to filter the solvent soak for 24 hours to see whether the phenomenon of dissolution to examine the quality of the filter membrane;
3, To distinguish the filter media material type: membrane have organic ,mixed and water series;
4, When filtering Aqueous type solvent filtration,if organic type membrane shall be used, the better way is to filter first and then mixed, after mixed,use the membrane which with the higher proportion of the mobile phase;
5, The membrane has no up and down aspect for most materials, regardless of anyway, but the best smooth face up, rough side of the filter effect will be fine down;
6, Waste filter should not be discarded, the filter membrane on the environment pollution, should not be refined, the collection of unified treatment;
7, Solvent filter supporting oil-free vacuum pump pump, do not wait for the liquid after the air and then pull the hose, not pull out, otherwise it will flatten the hose, when solvent left left a little liquid please close the vacuum pump in time;
8, To avoid secondary pollution of the filtered solvent .
