Munktell CACN SYRINGE FILTERS
Cellulose acetate syringe filters are used for the filtration of volumes of up to 100 ml. The syringe filter units are ideal for applications requiring maximum sample recovery such as: tissue culture preparation, sterile filtration and clarification of biological fluids, specimen solutions, protein and enzyme filtration, hydridization buffers and other aqueous solutions.
We supply them sterile or non-sterile in five different pore sizes: 0.2-0.45-0.8-1.2-5.0 μm. The 0.2 and 0.45 μm units can be supplied with the option of a micro-glass fibre pre-filter.

REGENERATED CELLULOSE SYRINGE FILTERS
Inside these syringe filters, there are hydrophilic and solvent-resistant regenerated cellulose membranes. These syringe filters are suitable for the ultra-cleaning of small volumes of samples for HPLC or GC.
We supply these syringe filters in two pore sizes – 0.2 and 0.45 μm – and in three sizes 4 – 15 – 25 mm.
