Membrane-Bottom Filter Plates

Membrane-bottom filter plates

96-well and 48-well polypropylene membrane-bottom filter plates bring convenience and speed to sample filtration on a microliter to milliliter scale. The individual sample wells or chambers have separate high-strength single or dual filter membranes to provide rapid filtration rates and to eliminate leakage or cross-talk between adjacent wells.

Key to membrane types:

PE = polyethylene

UHMW PE = ultra-high molecular weight polyethylene

PP = polypropylene

PES = polyethersulfone

PVDF = polyvinylidene difluoride 

GF = glass fiber

96-and 48-well polypropylene membrane-bottom filter plates bring speed and high throughput to sample filtration on a microliter to milliliter scale. The membrane-bottom individual sample wells or chambers have separate high-strength single or dual filter membranes to provide rapid filtration rates and to eliminate leakage or cross-talk between adjacent wells.

Key Features

  • High recoveries of both filtrates and particulate retentates
  • Multi-well format for simultaneous filtration of 96 or 48  different samples
  • Individual filter membranes to avoid cross-talk between adjacent wells
  • High well-to-well reproducibility
  • Range of membrane types and sizes
  • Suitable for vacuum manifold filtration or centrifugal filtration

All filter plates feature rigid polypropylene construction for chemical resistance and low binding and meet SBS footprint for use in robotic systems. Standard filter media include: glass fiber, PVDF polypropylene, polyethylene and polyether sulfone. Patent pending sealing process guarantees no well-to-well cross talk and weeping and allows superior recovery performance. 

Applications

  • Nucleic acid binding
  • DNA binding
  • DNA/RNA purification
  • Purification of PCR products
  • High-throughput preparation of YAC DNA
  • High-throughput drug synthesis
  • Bead/resin based assays
  • Cell-based receptor binding assays
  • Size exclusion
  • Concentrate, purify and desalt proteins, peptides, oligos, DNA and RNA
  • Recover proteins, oligos and RNA from polyacrylamide gels
  • Filtration and Filtrate Collection 

96-well Filter Plates with 6.24 mm well size and 19.35 sq mm filter area are good for size exclusion, to concentrate, purify and desalt proteins, peptides, oligos, DNA and RNA and also to recover proteins, oligos and RNA from polyacrylamide gels. Plates comply with industry standard for automation and are available with 10,000 and 30,000 MWCO membranes. 

96-well 2 ml Filter Plates with 8.23 mm well size come with polypropylene membrane for organic synthesis and with UHMW polyethylene membrane good for solid phase extraction.
