AP30034P0 Thick Absorbent Pad, 34 mm 45 
Add to Cart
  • Background Information
  • Cellulose support pads are used to reinforce filters in Millipore's monitors for contamination analysis. When saturated with growth medium, they can also be used for culturing microorganisms on membranes.To increase flow rate and throughput, our woven mesh spacers can be placed between filters in a serial filtration to prevent the downstream screen filter from "blinding" the upstream filter pores. Features & Benefits•Avoid membrane damage during high pressure or fast flow conditions •Spacers enable you to combine multiple stages of filtration into a single process step, saving time Applications:Air Monitoring, Environmental Monitoring, Aerosol Contamination Monitoring

AN5004700 Polypropylene Prefilter, hydrophobic, 5.0 µm, 47 mm 88 
Add to Cart
  • Background Information
  • Millipore polypropylene filters are constructed of 100% virgin polypropylene media. They are ideally suited for general clarifying and prefiltration applications including solvents, deionized water and bioburden reduction. They also provide broad thermal compatibility.The prefilters provide high particle retention, high dirt holding capacity and low pressure drop. They are designed for filtration of organic solvents, but they can also be used - once properly wetted with alcohol - for the filtration of aqueous solutions.Features & Benefits:•Compatible with aggressive solvents •Prefilters have high dirt-holding capacity Applications:General Prefiltration and Clarification, Suitable for Organic Solvents
