Simple simultaneous harvesting of samples from 96- and 24-well microplates Harvesting cells is fast and easy with PerkinElmer's FilterMate™ Universal Harvester. Our compact system harvests and washes all 96 or 24 samples simultaneously from shallow- or deepwell microplates. The FilterMate Harvester is available in several versatile configurations. There are FilterMate models suited for either our MicroBeta® or TopCount® Scintillation and Luminescence Counters, as well as a model designed for cutting filtermats for our Tri-Carb® Liquid Scintillation Counters or WIZARD® Automatic Gamma Counters. With any FilterMate model, it takes only minutes to process and transfer samples-onto integrated filter plates such as UniFilter® plates for counting on TopCount; onto dedicated filtermats for counting on MicroBeta; or onto plain filtermats with the OmniFilter™ harvester configuration. The MicroBeta FilterMate Harvesters are available in stainless steel to provide increased resistance to TCA (trichloroacetic acid). UniFilter Harvester-Ideal for TopCount Users This FilterMate Harvester is configured for harvesting UniFilter plates for analysis on the TopCount Microplate Scintillation and Luminescence Counters. UniFilters are 96- or 24-well microplates with built-in GF/B® or GF/C® filters for optimized harvesting of membrane receptors or cells. Harvesting and washing steps are performed 96 wells at a time using the simple, push button aspiration and wash control. The UniFilter plates go into the TopCount for analysis of up to 12 wells simultaneously. Should your assays require the larger size 24-well plate for higher sample loads, you can easily convert the FilterMate to the UniFilter-24 configuration. Simply remove four screws to replace the upper head and the wash/aspirate head. In this format, millions of cells or milligrams of membrane protein may be harvested. Key Features

  • Flexible-use 96- or 24-well formats, deep or shallow-well plates.
  • Short fluid path-minimizes the amount of wash fluid required and ensures more complete washing.
  • Separate hot and cold waste lines-helps minimize radioactive waste.
  • Versatile base-unit-enables switching from 96-to 24-well format and back in just a few minutes.
  • Built-in scrubbers-make it easy to detach adherent cells from well bottoms and ensure complete harvesting.
Key Applications
  • Cell proliferation assays (tritiated thymidine uptake)
  • Cytotoxicity assays
  • Receptor binding assays
  • Nucleic acid degradation
  • Trichloroacetic acid preparations
  • Cell wash station for adherent cell assays
