Manifolds Filtration Glass Funnel

Brief instruction of Manifolds Vacuum Filtration
    Manifolds Vacuum Filtration is used primarily in microbiological and analytical procedures that involve collecting a particulate (bacteria, precipitate, etc.) from a liquid suspension. Liquid poured into a funnel passed 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. Vacuum Filtration Holders and Manifolds are particular designed and produced for several samples filtrate at the same time. Because each filter holder have individual control valve, only one set vacuum pump can sustain the single or Multi-branch manifold filter operate together. While stainless steel nature of the Vacuum Filtration Holders and Manifolds can filtrate at 180℃temperature ;and the high-quality extra hard glass is elegant in workmanship, and be able to bear up  200℃range of temperature. The clamp of aluminum alloy designed rational and closed, it can make the filter bowl together with the middle filter head become an organic, and assure them airproof not to leak. Simultaneity, type 316Lstainless steel resistant to acids alkalis,and be able to bear corrosion, easy to high-temperature sterilization. Therefore, it makes the analyze result much more stabilization and trustiness.

Each holder have individual control valve, agility for use、convenience in antisepsis、high efficiency.
Test three or six samples at the same time, high sensitivity, low false –positive, and easy to operation.
Operation range: 
Widely used for chemistry analyze biochemical-pharmaceutical sanitation test environment test water quality analyze food staff, beverage and science research and so on.
Suitable Membrane: 
The choosing of the membrane filter is the key to the best filtration. The nature of membrane filter must suit for different chemical performance of the filter medium. At present mostly are PVDF(organic)、synthetic fabric colophony membrane(aqueous)、and Nylon membrane(both aqueous and organic). Our company also provide various kinds of imported membrane filter, the aperture is usually 0.22、0.45、0.8μm, and the suitable diameter isφ47 or φ50.
