The membrane types offered include cellulose acetate, polyethersulphone (PES), nylon and PTFE, in different sizes and porosities to cover a very wide range of applications
Sterlitech offers a wide variety of syringe filters for scientific needs.
The membrane types offered include cellulose acetate, polyethersulphone (PES), nylon and PTFE, in different sizes (from 3mm to 30mm) and porosities (from 0.1 to 0.5 micron) to cover a very wide range of applications.
Most filters are available sterilised and have an option for a glassfibre pre-filter.
Sterlitech's chemical compatibility chart will help in the selection of the right type of membrane for an application.
Sterlitech cellulose acetate syringe filters are hydrophilic and are appropriate for maximum sample recovery, such as tissue culture media preparation, sterile or non-sterile filtration and are ideally suited for protein and enzyme samples.
They are not compatible with organic solvents.
Sterlitech nylon syringe filters are hydrophilic and are designed for sterilisation or clarification of samples.
They are compatible with most solvents, however, using them with strong acids and methylene chloride is not advocated.
Sterlitech Polyethersulphone (PES) syringe filters are hydrophilic and well suited for maximum sample recovery such as media preparation, filtration and clarification of fluids, buffers, and other aqueous solutions in which low protein binding and low extractables are important.
They are compatible with most solvents; however, using them with strong acids is not advocated.
Sterlitech PTFE (Teflon) syringe filters are hydrophobic and are designed to filter most aggressive solvents, acids, and base samples.
PTFE is also an ideal choice for venting applications.
