Reusable filter holders

Full description

CHM® Glass filter holders


These versatile all -glass filter holders are supplied with a glass frit filter support. It ensures the uniform distribution of retained particles on the filter surface.
Recommended for colony counting and for collection of suspended solids.
The system composed of glass funnel and base with vacuum connector and receiving flask is supplied with:
ground glass outer and inner joints to connect to the receiving glass or with silicon stopper connector.


Re-usable CHM® filter holders


The filter holders are specially designed for clarification and sterilisation of aqueous and aggressive samples. These reusable devices are made in different materials in function of the applications.
Depending on the volume and the type of sample to be filtered, CHMLAB is offering 3 ranges of filter holders:
· Filter holder for volumes up to 10 ml (13 mm membrane diameter)
· Filter holder for volumes up to 100 ml (25 mm membrane diameter)
· Filter holder for volumes with more than 100 ml (47 and 50 mm membrane diameter)


CHM® HIN Stainless steel filter holder


CHM® HIN inox holder for solvents and chemicals.
The PTFE -coated surface on the top part is an important property of the filter holder and ensures leak proof sealing without a sealing ring.
The temperature resistance is extremely good, and the chemical compatibility depends only on the used membrane filter type.
Sterilisation: by autoclaving (max. 134ºC) or by dry heat (max. 180ºC).
The top part can easily be mounted on the bottom part using the tightening tool supplied.
Filter supports in the top and bottom parts allow filtration in either direction.


CHM® HPC Polycarbonate filter holder


CHM® HPC Polycarbonate holder for aqueous solutions.
This CHM® HPC filter holder is made of stable polycarbonate and contains a silicone gasket for leak proof sealing.
The polycarbonate material withstands numerous working and washing cycles.
It can be sterilized by autoclaving (max. 121°C).
Filter supports in the top and bottom parts allow filtration in either direction.
The holder has an excellent resistance to pressure; up to 7 bar of operating pressure.
The transparent top part allows the visual control of the correct fit.


CHM® HTF PTFE filter holder


CHM® HTF filter holder for organic solvents and aggressive chemicals.
Made completely of PTFE, this holder has a broad chemical compatibility and contains no trace elements which could be released into the liquid being filtered.
Easy cleaning. Autoclavable by dry heat at 180ºC.
It is indicated for particle removal from samples and reagents for analytical methods.
The construction of the holder ensures leak proof sealing without a sealing ring, and avoids twisting of the membrane filter when the top is tightened onto the base.
