application.
JULABO circulators are laboratory devices which are designed for the
temperature control of certain liquid media in a bath tank or with a
refrigeration unit. The bath fluids recommended by JULABO must be
used as tempering media.
Units with pump connections allow the tempering tasks to be carried
out in an external temperature control system.
JULABO circulators are not designed for the direct temperature
control of foods, semi-luxury foods and tobacco, or pharmaceutical
and medical products.
• Direct temperature control means unprotected contact between
the object and the tempering medium (bath fluid).
• The devices are not suitable for use in potentially explosive
environments.
