PROCLEAR PP
PROCLEAR GF
PROCLEAR GP

 

PROCLEAR PP

  • Polypropylene depth media
  • Micron rating from 0.6 to 100µm

  • Extremely robust, capable of withstanding aggressive conditions

    •Aggressive chemicals, high / low pH
    •Physical factors (temperature, flow rate, differential pressure etc.)
  • Example application: particulate removal prior to sterilising filter buffers

PROCLEAR GF

  • Glass fibre depth media
  • Micron rating from 0.6 to 10µm
  • Highly retentive
  • High dirt-holding capacity
  • Example application: Clarification of bioreactor output prior to downstream processing

PROCLEAR GP

  • Glass fibre / polypropylene composite depth media
  • Micron rating from 0.5 to 0.6µm
  • Extremely retentive
  • High dirt-holding capacity
  • Assurance against particle shedding
  • Example application: Growth media pre-filtration

PROPOR SG
PROPOR HC
PROPOR BR

 

PROPOR SG

  • Polyethersulfone (PES) membrane
  • 0.2µm rated, sterilising grade
  • Also available in 0.1µm and 0.45µm
  • High flow rates = smaller filter required / quicker processing time
  • High throughputs = larger batches
  • Low product binding = higher product yield
  • Broad-spectrum chemical compatibility
  • Low extractables = low leachables into drug product
  • Example applications: buffer filtration, final fill

PROPOR HC

  • Polyethersulfone (PES) membrane
  • 0.2µm rated, sterilising grade
  • Integral PES highly asymmetric pre-filter layer
  • High capacity, high dirt holding = high throughput with difficult to filter products
  • Broad-spectrum chemical compatibility
  • Example application: Growth media filtration

PROPOR BR

  • Polyethersulfone (PES) membrane
  • 0.2µm nominally rated, non-sterilising
  • Integral polyester pre-filter layer
  • Bioburden reduction
  • >5log reduction ASTM F838
  • High flow rates = smaller filter required / quicker processing time
  • Low product binding  = higher product yield
  • Broad-spectrum chemical compatibility
  • Example application: Chromatography or TFF pre-filtration
