Harvard Apparatus’ new 96-WELL and 384-WELL 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.
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.
96-Well Ultra-Filtration Plates with 6.24mm 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.
Distinctively constructed 384-Well Filter Plates have short drip directors, square to round wells for maximum working volumes and variety of filtration media and can also be used robotically as well as for vacuum or centrifuge filtrations.
Application specific Filter Plates and Filtration Devices to the Biopharmaceutical industry can be custom ordered. Other package sizes and bar-coding are available.
