Product Specifications

Low Temp Good Value

The NESLAB ULT Series controls the tem­perature of the reservoir, cools the fluid, and
circulates this fluid externally. Temperature
remains steady to a very tight tolerance to
give you an excellent calibration source.

When it comes to heat removal, the
environmentally responsible refrigeration
system lets you cool more equipment, glass­ware, or instrumentation than you can with
a benchtop circulator. A good value for low
temperature applications.

The ULT Series has an industrial-grade
circulating pump that delivers consistent
flow which allows fluid to circulate long
distances, even through small I.D. tubing.
And you no longer need to locate your
bath circulator next to your application.

Plus for those applications requiring a
wider temperature range, such as reaction
vessel heating and cooling,

Thermo Electron
Corporation offers an optional extended
temperature range ULT unit that can
circulate between -80°C and +80°C.

Choose Range of Options

While each ULT unit comes with many
standard features, a full range of options
and accessories is available to meet your
specific application needs.

NESLAB ULT Series Bath Circulators

Designed to achieve low temperatures and maintain
excellent temperature stability for consistent results

The ULT Series refrigerated bath
recirculators are self-contained,
compact, cooling units designed for
circulating to external applications.
They provide

temperature stability
