Membrane-bottom individual sample wells have separate high-strength single or dual filter membranes to provide rapid filtration rates and to eliminate leakage or cross-talk between adjacent wells
Harvard Apparatus's new 96-well and 384-well filter plates bring speed and high throughput to sample filtration on a microlitre to millilitre scale, it says.
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.
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 fibre, PVDF polypropylene, polyethylene and polyether sulphone.
The patent pending sealing process guarantees no well-to-well cross talk and weeping and allows superior recovery performance, says Harvard.
96-well ultra-filtration plates with 6.24mm well size and 19.35mm2 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 2ml filter plates with 8.23mm well size come with polypropylene membrane for organic synthesis and with UHMW polyethylene membrane good for solid phase extraction.
