Grant R series low temperature baths/circulators (referred to as R unit in this text) are
designed to be used with a Grant Optima
™ heating circulator (referred to as Optima unit
in text). They provide a source of cooling for many sensitive analytical procedures.
Applications requiring the precision temperature control of samples include
spectrophotometry, viscometry, refractrometry and electrophoresis. Grant’s range of
more powerful chillers are ideally suited for applications requiring the removal of the
mechanical or electrical heat produced in apparatus or machinery, combined with a
higher pressure flow for faster heat removal within restricted systems.
