Multigrade GMF 150 预滤膜150
Multigrade GMFl50-是一种按密度分级的玻王割故纤维滤纸。有两种型号可供使用，大小规格分别为1μm和2μm以适用于各种标准的膜容器。
The Whatman GMF 150 is a multilayer glass microfiber filter with a coarse top layer (10 µm) meshed with a finer layer of 1.0 µm or 2.0 µm. Manufactured from 99% borosilicate glass microfiber, the filter is binder free. It is the ideal prefilter for higher particulate loading capacity with faster flow rates.
The GMF 150 allows for:
- Higher particulate loading capacity
- Faster flow rate
- Extended life of filter
Multiple porosities, greater filtration efficiency
The GMF 150 represents a new dimension in separation science leading to faster and more cost-effective filtration. In application, the GMF 150* traps larger particles in the pores or on the surface of the coarse layer while the medium sized particles are caught in the interface meshing. The smaller particles are netted in the interstices of the fine layer.
