Harvester Eliminates Multiple Pipetting

Biochemists, pharmacologists, and cell biologists frequently need to perform assays requiring the detection and quantitation of radioisotopes during such procedures as receptor binding assays, antigen detecting, metabolic/enzymatic as- says, and protein or antibody labeling.

Biochemists, pharmacologists, and cell biologists frequently need to perform assays requiring the detection and quantitation of radioisotopes during such procedures as receptor binding assays, antigen detecting, metabolic/enzymatic as- says, and protein or antibody labeling. These assays invariably demand the analysis of a large number of samples, necessitating multiple pipetting. Consequently, such assays are prone to pipetting errors. Cambridge Technology Inc., based in Watertown, Mass., now markets the Model 2000 PHI) Sample Harvester, designed to obviate the need for repetitive pipetting and reducing greatly the time required to perform such assays. The Model 2000 harvests 24 samples at a time onto 25mm diameter collection sites and will insert the samples into 12- x 75-mm test tubes, gamma tubes, minivials, or standard 20-mi scintillation vials. Trays are also available for depositing samples directly into Hewlett-Packard or Beckman 12 liquid scintillation vial cassettes; the basic system, priced at $4,800, includes a choice of...
