Millipore Filter Apparatus – Borosilicate Vacuum Filtration Assembly

Millipore Filter Apparatus – 47 mm Borosilicate Vacuum Filtration Assembly

The Millipore Filter Apparatus is a laboratory vacuum filtration assembly designed for filtering aqueous solutions, biological fluids, tissue culture media, and HPLC mobile phases. Manufactured by Elmo Agencies, a scientific manufacturer in Ambala, this assembly combines borosilicate glass components with a 47 mm filter support system for practical laboratory filtration applications.

Vacuum filtration uses reduced pressure to draw a liquid through a filter, helping separate suspended particles from the liquid. The Millipore Filter Apparatus is designed for this type of filtration and includes a funnel, filter support base, filtration flask, and clamp.

Its borosilicate glass construction makes the assembly suitable for routine laboratory use where chemical resistance and thermal stability are important properties of the glassware.

Specifications

Assembly Components

The filtration assembly consists of:

• 300 ml borosilicate glass funnel
• 47 mm integrated filter support base
• 1000 ml borosilicate glass filtration flask
• 47 mm aluminium clamp
• G2 sintered support disk with 40–90 µm porosity

The clamp holds the funnel and support base securely during the filtration process.

Filtration Support

The 47 mm sintered disk serves as the filter support and has G2 porosity in the specified 40–90 µm range. The 47 mm filter format provides an effective filtration area of approximately 9.6 cm².

The assembly is designed to promote efficient liquid flow while helping reduce foaming during filtration.

Common Applications

HPLC Mobile Phase Filtration

Used for filtering buffers and solvents before HPLC procedures to help remove particulate matter.

Tissue Culture Media

Suitable for filtration of culture media and related laboratory solutions where particulate removal or sterile filtration is required with an appropriate membrane.

Biological Fluid Filtration

Can be used to clarify and filter biological samples and fluids, depending on the selected filter membrane and laboratory protocol.

Aqueous Solution Filtration

Suitable for vacuum filtration of various aqueous laboratory solutions.

Pharmaceutical and Analytical Laboratories

Useful for sample preparation, routine filtration, and laboratory quality-control procedures.

Suitable For Millipore Filter Apparatus

• Analytical and quality-control laboratories
• Microbiology and biotechnology laboratories
• Pharmaceutical research laboratories
• HPLC and analytical chemistry applications
• Colleges and research institutions
• Laboratory filtration and sample preparation

The G2 sintered disk specified for this assembly is a support component with 40–90 µm porosity. It should not automatically be considered equivalent to a sterile membrane filter. For applications such as sterile filtration or fine particulate removal, select the appropriate membrane/filter specification according to the laboratory procedure.

Conclusion

The Millipore Filter Apparatus by Elmo Agencies is a practical 47 mm borosilicate glass vacuum filtration assembly featuring a 300 ml funnel, 1000 ml flask, G2 sintered support disk, and aluminium clamp. Its design makes it suitable for laboratory filtration of aqueous solutions, HPLC-related sample preparation, biological fluids, and research applications.
