Description
Disposable vacuum filter system is a filtration system
commonly utilized in research labs for large sample separation and
purification. They are designed to provide a convenient and
efficient method for filtering liquids, removing particulate
matter, and sterilizing or clarifying solutions.
The disposable filter system includes one membrane filter,
graduated funnel made of clear polystyrene and a polystyrene
receiving bottle or container. It combines with a vacuum pump to
provide pressure differentials across the membrane filter allowing
liquid to pass through and retain particulates on the membrane. The
processed liquid is collected in the receiving bottle underneath.
The filter membrane is made of materials, such as polyethersulfone
(PES), Nylon, MCE ,PVDF etc. and comes in various pore sizes
(0.10μm, 0.22μm and 0.45μm) to accommodate different applications.
There are multiple combinations of top funnel and receiving bottle
volumes (250mL, 500mL and 1000mL).
Features
- Membrane filter available in 0.22μm and 0.45μm pore sizes for
different applications
- Neck color coded: Green (PES), Dark blue (MCE), Purple (Nylon) and
Yellow (Hydrophilic PVDF)
- Funnel and receiving bottle volume size available: 250 , 500 and
1000ml
- Filter Diameter: 50mm membrane for 250ml units and 90mm for 500 ml
and 1000ml units
- Filtration area: 250mL (17 sq cm) and 500 mL (64 sq cm)
- Light weight and heavy wall construction
- Reservoir bottles feature easy grip for improved handling with
simple tightening and loosening adjustments
- Designed with a wide mouth for easy access for efficient and smooth
pouring
- Engraved graduation ensures durability
- Hose connector can fit multiple hose diameters
- Detergent free, tissue culture compatible and heat sealed to the
support grid to maximise flow rate, reduce foaming and protein
denaturation

Application
- Sterile Filtration of Liquids: Used for aseptic filtration of
culture media, buffers, and other solutions to ensure a sterile
environment for cell culture and microbiological applications.
- Biological Sample Clarification: Effective in removing particles
and debris from biological samples such as cell culture
supernatants, lysates, or fermentation broths to obtain clarified
solutions for downstream processes.
- Water and Environmental Analysis: Employed in environmental
monitoring and water analysis to filter out particulate matter,
microbes, or contaminants from water samples prior to analysis.
- Pharmaceutical Filtration: Applied in pharmaceutical laboratories
for the filtration of drug formulations, reagents, or solutions to
ensure purity and eliminate contaminants. Laboratory Research and
Experiments: Widely utilized in research laboratories for various
applications such as sample preparation, purification, or
clarification steps in experiments involving proteins, nucleic
acids, and other biomolecules
Membrane options
- PES-The fastest flow rate, the lowest protein binding and
low extractables and are best for filtering cell culture media.
- MCE-Filtration of aqueous solutions, effectively binds trace
proteins.
- Nylon-Naturally hydrophilic, surfactant-free and offer the
lowest extractables.
- PVDF-Suitable for aqueous solutions and organic solvent
filtration.
Warning
- With the bottle Top Filter, don't use plastic or glass bottles,
flakes or other containers that are not designed to withstand
vacuum
- Don't use on media bottles larger than 2L
- Working temperature:4℃~37℃
- Apply vacuum pressure. A differential of 0.03-0.06Mpa. Decrease
pressure if excessive foaming occurs.
- Hand tighten the Bottle Top Filter onto the bottle neck,do not over
tighten.
- Always use safety equipment,including eye protection when
working with any vacuun system.
- Work in a sterile(Laminar flow) hood to assist in maintaining
sterility.
- Not recommend to recycle products that have been used with
hazardous materials , hazardous waste, or biohazard items .
