Laboratory vacuum-filtration hardware
Disposable vacuum-filtration units, reusable funnels and support hardware for laboratory clarification, membrane filtration and parallel sample processing.
Membrane rating and hardware fit are configuration-dependent
Filtration formats
Filter funnels and holders provide a controlled interface between the sample, filter medium and vacuum source. Disposable vacuum filters can combine the funnel, membrane and receiver in one ready-to-use assembly, while reusable funnels and holders allow a disc membrane to be selected for the method.
Multi-branch manifolds support parallel filtration and individual vacuum control for microbiology or analytical workflows. Selection should consider sample volume, membrane chemistry, retention, filter diameter, effective area, holder material, branch count, vacuum source and the required cleaning or sterilization cycle.
Integrated funnel, membrane and receiver configurations simplify small-batch clarification and compatible sterile-filtration work.
Workflow Integrated disposable unit
Reusable or disposable funnel formats allow the membrane chemistry and disc to be selected for the analytical or microbiological method.
Workflow Selected disc membrane
316L stainless-steel multi-branch manifolds provide stable support for repeatable microbiology, water and analytical filtration runs.
Processing mode Parallel vacuum filtration
Filter-path and hardware selection
The filtration result depends on the complete path—not only the nominal pore rating. Sample chemistry, particulate load, membrane material, effective area, vacuum level, holder seal and cleaning or sterilization exposure must be reviewed together.
End-user applications
Select the format around the actual sample, required separation, method, throughput and contamination-control strategy.
Vacuum filtration of aqueous laboratory solutions before use, storage or downstream processing.
Particulate removal before instrumental, biological or other analytical workflows.
Membrane-filtration preparation for recovery, incubation and colony-counting methods.
Parallel filtration of water, beverage, environmental and process samples.
Screening interchangeable disc membranes and holder configurations for a defined laboratory method.
Self-contained disposable units where simplified handling and reduced preparation are priorities.
Quotation guidance
A complete RFQ should describe the sample, required filtration result, membrane, capacity, hardware interfaces, lifecycle and documentation expectations.
Provide sample type, chemistry, particulate load, volume and filtration objective.
Select membrane or depth medium, retention or pore rating and the required sterility claim.
State funnel or receiver volume, disc diameter, effective area and acceptable hold-up.
Identify holder, manifold branch count, vacuum source, tubing and receiver interface.
Confirm disposable or reusable use, sterilization cycle, packaging and certificate requirements.
Define any sterilizing-grade claim, recovery method, vacuum limit and configuration-specific qualification evidence.
Configuration matrix
Offered combinations are configuration-dependent. Confirm sample compatibility, membrane rating, filter diameter, effective area, vacuum limit, holder seal and approved cleaning or sterilization exposure before final selection.
