11/9/2020 · Rotary vane pumps pull a strong vacuum and use ½ hp to ⅓ hp. Oil-free pumps use ⅙ hp to ⅛ hp. Noise level (dB) - how much noise the pump makes when operating. Oil-free pumps are generally quieter ranging from 50 dB to about 68 dB for oil-sealed pumps. Water aspirators are the quietest since they do not have a motor.
The PTFE support can filter acidic solutions at a higher flow rate. Available in four graduated funnel capacities 100, 300, 500, or 1000 mL. The No.8 silicone stopper mounts in a standard 1L vacuum filter flask or manifold cup. The optional 2"
Protect vacuum equipment from corrosion and contamination POREX® plastic filter housings are self-contained preliminary filters for both gases and fluids. Designed to protect vacuum equipment, pneumatic controls units, pumps and motors from corrosion and chemicals, our plastic filter housings are an economical pre-filtration alternative for potable water and reverse osmosis systems.
Our high-purity POREX Virtek ® PTFE, PE and PP products have precise porosity allowing for consistent electrical and flow properties, along with: Very low contamination for critical processes. Precise pore size and volume control and customization to multiple shapes and thicknesses.

POREX® suction canister filters effectively filter the air and protect the vacuum system lines from contaminants in the fluid contained within the collection canister. Comprised of porous plastic containing a functional additive, our suction canister filters behave as a valve by automatically and instantly shutting off airflow from the collection canister when collected fluids come in contact with the filter.
Sterlitech provides membrane, syringe, capsule filters & custom filter and assembly options for laboratory-scale filtration. Q. What variables affect the performance of a filter? A. Viscosity: The viscosity of a liquid determines its resistance to flow; the higher the viscosity, the lower the flow rate and the higher the differential pressure required to achieve a given flow rate.
Oct 8, 2019 - Laboratory Filtration is a vital process in many biological and chemical labs. Necessary pressure gradient can be created with many methods including gravity flow, vacuum pressure, high pressure, and centrifugal force. See more ideas about centrifugal
The Vacuum Pump is simplifies the process of vacuum filtration, eliminating the need for a water source and vacuum aspirator. It is also much more economical than a costly electric vacuum pump. The pumping rate is 15ml per stroke and will displace up to 725ml of air. The pump is fitted with.
Hydrophobic PTFE Membrane Filters / Type 11842. The hydrophobic PTFE membrane filters are made of polytetra-fluorethylene (PTFE) only and are therefore permanently hydrophobic. Unlike hydrophilic filter types, they are not wetted by air humidity. Added to Shopping Cart.
