Three-branch Glass Funnel Manifolds 3BGM
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 316L stainless 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.

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.
Efficient Multi-Sample Filtration with the Three-Branch Glass Funnel Manifold 3BGM
Streamline your laboratory workflow with the Three-Branch Glass Funnel Manifold 3BGM—a precision-crafted, borosilicate glass filtration system designed for simultaneous vacuum filtration of up to three samples. Ideal for environmental testing, pharmaceutical QA, microbiology, and research labs, this manifold delivers consistent, contamination-free results while saving time and bench space.
Built for Simultaneous, Reliable Filtration
The 3BGM Three-Branch Glass Funnel Manifold features three independent filtration ports with standard taper joints (typically 24/40 or 29/32, customizable), compatible with common glass funnels and membrane filter holders. Its all-glass construction ensures chemical resistance to acids, bases, and organic solvents, while the integrated sidearm connects directly to a vacuum source for rapid, uniform suction across all branches.
- Borosilicate Glass (3.3) – Highly resistant to thermal shock and corrosive chemicals for long-term durability.
- Three Independent Filtration Channels – Process multiple samples in parallel without cross-contamination.
- Standard Taper Joints – Ensures secure, leak-free connections with compatible funnels or filter holders.
- Central Vacuum Port with Heavy-Wall Tubing Adapter – Provides stable, even vacuum distribution.
- Easy to Clean & Autoclavable – Smooth internal surfaces prevent residue buildup; suitable for sterilization.
- Compact, Stable Base Design – Minimizes tipping during operation and fits standard lab setups.
Trusted for Reproducible Results
Unlike plastic manifolds that may leach contaminants or degrade with solvent exposure, the 3BGM offers inert, transparent performance—allowing visual monitoring of filtration progress. It’s widely used for membrane filtration in water quality testing (e.g., total suspended solids, microbial analysis), HPLC sample prep, and sterile clarification of sensitive solutions.
Whether you’re running routine QC checks or conducting environmental compliance testing, the Three-Branch Glass Funnel Manifold 3BGM enhances throughput without compromising purity or precision.
Upgrade your filtration setup with a lab-grade solution that’s as efficient as it is reliable.
