NOH® Vacuum Filters

N.O.H International


Vacuum Filter is used primarily in microbiological and analytical procedures that involves collecting a particulate (bacteria, precipitate, etc.) from a liquid suspension. Liquid poured into a funnel passes through a filter, which retains the particulate, and filtrate can be collected into a filter flask, directly or via a vacuum manifold. Applying vacuum reduces process time compared to gravity flow.
Multi-branch Manifold filter is particular design and produce for several samples filtrate at the same time. At present domestic laboratory filtrate liquid usually adopts the glass nature core, while this method only filtrates one sample once, and it has low speed, low efficiency, and less labor exertion. It is more convenience for the operator who needs to filtrate several samples at the same time.
N.O.H International supplies a wide range of vacuum filter holders, Glass Solvent Filters, Multiple Filtration Systems, and Accessories. Select from glass or stainless steel assemblies with funnels holding from 15 to 1000 ml. NOH® Vacuum filters can be steriled by autoclave.


Widely used for chemistry analyse
Biochemical-pharmaceutical sanitation test environment test
Water quality analyse
Foodstuffs and beverage test
Science research and so on.
Vacuum filter aqueous, organic or corrosive liquids for particulate contamination analysis.
It is recommended for HPLC solvent filtration and it has the function of outgas to guarantee the clean of mobile phase and avoid the blockage of HPLC liquid flow path.
