• Excellent temperature uniformity
• LED displays for temperature, speed, and time
• Cool touch, chemical resistant housing
• Includes RTD temperature probe kit
Professional Round Top Hotplate-Stirrers are designed for applications that require
exceptional accuracy, stability, and repeatability. Exclusive safety features help protect
operator and sample. Enhanced microprocessor control offers an external RTD probe
option that delivers superior temperature control of the sample. Stirring function, with
continuous duty motor and powerful magnet, maintains set speed even under changing
load or viscosity. Separate LED displays for temperature, speed, and time allow user to
view all settings at once.
Operating Features:
Low profile design:
Takes up minimal space and fits easily into fume hoods. Spill-
resistant design channels fluids away from internal components.
Microprocessor control:
Advanced electronics regulate both heating and stirring and
bring samples to temperature quickly and efficiently. Temperature measurement is
controlled more accurately by utilizing an internal RTD. Speed is precisely controlled,
and provides consistent stirring at all speeds. Powerful continuous duty motor delivers
dependable and reliable stirring.
Control panel:
Touch pad controls with easy-to-read, independent LED displays
for temperature, speed, and time allow operator to view all settings at once. Provides
repeatable and accurate results every time and is easily visible from outside fume hoods
or across lab benches. Shows set-point and actual temperature. Timer will display elapsed
time or when programmed to user defined limit, will shut off unit when time reaches zero.
Display will show last used settings, even after power has been turned off.
Stainless steel top plate:
5.3” (135mm) diameter top plate is durable and will not crack.
Accepts optional VWR
base plate that holds a variety of block options for holding multiple
samples at one time.
Built-in support rod holder:
Rear housing features an off centered, built-in support rod
holder with locking knob that accepts the probe kit.
Safety Features:
Cool touch housing:
Housing is made of a heat resistant polymer that is not only cool to
the touch, but is also chemical resistant.
Hot top indicator:
For additional safety, hot symbol warning light is illuminated when heat
is turned on and remains on until top plate cools down.
Stir protection:
If stirrer motor stops or fails, unit will automatically shut down heater.
Speed ramping feature:
Slowly increases speed for improved safety and enhanced
coupling. Avoids splashing, improves spin bar control and provides excellent low end
speed control.
Maximum temperature limiting:
(plate over temperature limit) Ensures plate temperature
will never exceed users programmed set temperature limit, allowing for control of samples
with sensitive flash points.
Audible alarm:
In timed mode, alarm will sound when time reaches zero or when unit
reaches set-point temperature.
