More About this Item

Mixed cellulose ester (MCE) membranes are made from over 90% cellulose nitrate and 10% cellulose acetate for strength and thermostability. Can be safely exposed to temperatures up to 130°>C (266°>F). Can be used for many laboratory applications including filter sterilizing biological fluids, microbiology, contamination analysis, and air monitoring.

What is the max and min pH of a fluid I can pass through this filter? Will the filter dissolve or degrade at a pH as low as 2 or as high as 12?


This membrane is made up of cellulose nitrate and cellulose acetate. The degradation rate will depend on the specific fluid that is passing through the filter. This filter is suggested to be used with hydrophillic fluids. For hydrophobic fluids like solvents a PTFE filter would be a better option.


What is the pressure drop across these filters?


There is no pressure loss data that is specified for this membrane. Typically this will be a function of the filter holder that will be used.


For placing in a filter holder, does one also include the blue protective paper (on down-stream side of the white membrane)?

No, the blue paper is meant to keep the (white) membranes from sticking together or using more than one at a time.


Is the surface smooth enough to view under the microscope without confusing surface defects or fibers as particles/fibers collected from filtration?


Generally speaking, yes. The membranes are frequently used for microscopic examination of filtrants. No material is perfectly flat, and the viewer will need to differentiate between wrinkles, membrane fibers, and filtered particles. The level of difficulty is based on the size and structure of what was filtered.


What are the dimensions of the package (lenght x width x height). Need to size a box to hold this and other components.

The dimensions are: Height (in.)1.45, Length (in.)2.55, Width(in.)2.55.


does it works for DNA retain

The level of extractables in membrane filters has become more important with advances in filtration or adsorption techniques. In particular, pharmaceutical, immunological and biomedical tissue culture and trace analysis applications can be adversely affected by high extractable levels. Cellulose nitrate membrane filters have a low level of extractables, generally below that of other membranes of a similar type. These membrane filters are normally autoclaved at 121°C without loss of integrity. This is the standard membrane filter for the majority of laboratory applications involving particles and cells. Cellulose Nitrate membranes are not generally used when low protein binding is needed. So, yes these will retain DNA. Nylon is also very good at protein binding. PES, PVDF, and cellulose acetate should be used if low protein binding is needed.


Are these filters, hydrophilic? OK for SDI test?


Yes, cellulose nitrate filters are hydrophilic by nature. These will work well for silt density testing, but if you are following ASTM guidelines you may want to check their most current requirements since we do not have them on file.
