Multiple Vacuum Filtration System

The Multiple Vacuum Filtration System is a modular manifold setup designed for simultaneous, efficient filtration of three or six samples using a shared vacuum source. It features a stainless steel manifold with independent control valves per station, allowing selective operation and easy cleaning. The system supports both stainless steel and glass filtration units, enabling compatibility with a range of sample types from microbiological testing to food and environmental analysis. A single glass collection bottle handles effluent from all units, reducing setup complexity and consumable use.

Independent valve control per station allows selective filtration without affecting other samples
Modular design supports 1, 3, or 6 units on a single manifold, adapting to batch size needs
Stainless steel manifold and components resist corrosion and withstand repeated cleaning
Shared collection bottle reduces the number of containers needed and simplifies waste handling

Where It Is Used

Applications And Buyers

Application Scenarios

Performing parallel microbiological testing for E. coli in water and food samples across multiple batches
Conducting residue analysis on pharmaceuticals and cosmetics with high throughput and consistent results
Filtering multiple beverage samples (e.g. beer, juice) for cold sludge or particulate content in one run
Carrying out serial filtration in environmental labs for wastewater or soil extract analysis
Supporting contamination testing in pharmaceutical manufacturing with rapid, repeatable filtration

Who It Is For

Pharmaceutical QC labs needing to process multiple samples under strict contamination control
Food and beverage labs performing routine particulate testing on liquids and semi-solids
Environmental testing facilities handling large sample volumes from water and wastewater sources
Research labs conducting biochemical or hydrobiological studies requiring parallel sample processing
Lab distributors seeking a flexible, scalable filtration system for multiple client applications

Problems It Solves

Manual handling of multiple single-funnel setups increases time and risk of cross-contamination
Lack of independent valve control forces all samples to run simultaneously or in sequence, reducing flexibility
Multiple collection bottles increase waste, storage needs, and cleanup effort
Single-use filtration systems become costly at high sample volumes due to repeated consumable purchase
Inconsistent filtration rates across samples due to shared vacuum lines without individual regulation

Comparison

Compared With The Alternatives

Versus Single-funnel vacuum filtration

The multiple system reduces labor and setup time by allowing parallel processing, while maintaining independent control per sample

Versus Disposable multi-channel filtration systems

This system is reusable and reduces long-term consumable cost, though it requires cleaning between runs

Versus Shared vacuum manifold with no individual valves

Independent valves allow selective operation, enabling partial runs and easier disinfection

Versus Glass manifold systems

Stainless steel manifold offers better durability and resistance to mechanical stress during cleaning and reuse

Versus Integrated filtration benches

This modular system is more flexible and scalable, allowing labs to expand capacity incrementally without full system replacement

Use Guide

How To Use It

Select the manifold configuration (MVF0101S, MVF0103S, etc.) based on the number of samples to process
Attach the filtration units to the manifold using the flange interface; ensure seals are intact
Connect the vacuum hose to the manifold inlet and the collection bottle to the outlet
Open the control valve for each station only when ready to start filtration
Monitor flow rate and pressure; adjust vacuum level if one station blocks early
After use, disconnect units, clean with appropriate solvent or detergent, and dry before storage
Replace glass components if cracked or chipped; inspect seals regularly

FAQ

Questions Buyers Ask

Can I use this system for microbiological testing?

Yes. The system is suitable for microbiological QC, including E. coli detection, when used with sterile filtration units and proper aseptic technique.

What is the difference between the stainless steel and glass filtration units?

Stainless steel units are more durable and resistant to impact; glass units are chemically inert and suitable for sensitive analyses where metal leaching is a concern.

How many samples can I run at once?

The system supports 1, 3, or 6 samples simultaneously, depending on the manifold model selected (MVF0101S, MVF0103S, MVF0106S, etc.).

Can I use a different size collection bottle?

The system is designed for a single 300ml glass bottle. Using a different size may affect vacuum balance and drainage efficiency.

Is the manifold compatible with standard vacuum pumps?

Yes. The manifold uses standard fittings and connects to any vacuum source with a compatible hose connection.

Can I buy individual components like a single funnel or manifold?

Yes. Individual components such as the MVFF300G (glass funnel) or MVFSM03 (manifold for three units) are available for replacement or expansion.

Do you offer private-label options?

Yes. The Microlab OEM division supports private-label printing, custom packaging, and component sourcing for distributors and lab brands.
