The Grant R refrigerated bath and circulator range provides outstanding performance for routine and sophisticated applications requiring accurate temperature control in the range of -30 to 100\u00b0C.\u00a0A choice of 4 heating circulators combined with a powerful R refrigeration unit offers a cost-effective and efficient solution for low temperature applications.<\/p>\n

The Grant R4R, which can be combined with any of our T100, TC120, TX150 or TXF200 heating circulators, offer a number of features:<\/p>\n

    \n
  • Stability of up to\u00a0\u00b10.1\u00b0C<\/li>\n
  • Up to 3 years warranty<\/li>\n
  • No spill valved front drain<\/li>\n
  • 3 preset programs<\/li>\n
  • Large 20 litre tank and accessible bath for immersion of samples<\/li>\n
  • Environmentally friendly refrigerant<\/li>\n
  • Robust construction<\/li>\n
  • 900W of cooling power<\/li>\n
  • Quiet<\/li>\n
  • Built in Britain<\/li>\n
  • Range of accessory hosing, connectors, software, additional pump and temperature probes available<\/li>\n<\/ul>\n

    Note: The refrigeration unit can be switched off independently of the\u00a0heating circulator\u00a0to allow heating only applications. All the refrigeration base units can be used up to a maximum temperature of 100\u00b0C.<\/p>\n<\/div>\n<\/div>\n

    Alternatively, Grant RC series of recirculating chillers (closed circulators) can be used. These are generally needed for more powerful cooling requirements, e.g. the removal of mechanical or electrical heat produced in apparatus or machinery. Please contact\u00a0marketing@biosan.lv\u00a0for advice.<\/p>\n

    Choosing a refrigerated bath and circulator from:<\/p>\n

      \n
    • The T100 + R4R series with digital control, 0\u00b0 to 100\u00b0C<\/li>\n
    • The TC120 + R4R series with digital control and integral pump, \u201325\u00b0 to 100\u00b0C<\/li>\n
    • The TX150 + R4R series with digital control, integral pump and enhanced programming features, \u201330\u00b0 to 100\u00b0C<\/li>\n
    • The TXF200 + R4R series with digital control, enhanced integral pump and sophisticated programming features, \u201330\u00b0 to 100\u00b0C<\/li>\n<\/ul>\n

      We recommend the following liquids for use with refrigerated thermostatic baths and circulators:<\/p>\n

        \n
      • \u201350 to 50\u00b0C: Silicone oil \u2014 low viscosity
        \n(Bayer silicone M3)<\/li>\n
      • \u201330 to 30\u00b0C: 50% water 50% antifreeze
        \n(inhibited ethylene glycol)<\/li>\n
      • 0 to 30\u00b0C: 80% water 20% antifreeze
        \n(inhibited ethylene glycol)<\/li>\n
      • 5 to 99.9\u00b0C: Water<\/li>\n<\/ul>\n
