GL Chromatodisc Syringe Filter
GL Chromatodisc PF Syringe Filter, syringe filter with prefilter for Hydrophilic Samples
GL Chromatodisc 25APF
The GL Chromatodisc PF is designed to prevent clogging of the filtration membrane by filtering samples with a high content of contaminants through the use of non-woven borosilicate glass fiber fabrics, which have a unique pore structure in addition to A-type membrane.
Use
- Primary filtration of groundwater, soil water, etc. with high contaminants
- Filtration of tablet ingredients
