Frequently Asked Questions

I have a beaker of water on my hot plate and set the temperature
Q
for 550°C. Why does the display setting blink and not remain
constant?
The display will blink at any time when the temperature sensor is not
within range of the set temperature value. The temperature measured
by the sensor is a composite of the temperature of the heating element
located beneath the sensor, the ceramic top above the sensor, and the
very small air space around the sensor. Water requires a substantial
amount of heat in order to boil yet remains at a constant temperature
of 100°C for the duration of the boiling process. Although the heating
element is producing maximum heat at the 550°C setting, the water
consumes this heat so quickly during the boiling process that the heat
is unable to raise the temperature measured by the sensor to within
range of the 550°C set value.
How long does it take to bring a beaker of water to boil?
Q
Using a 600 mL PYREX
®
beaker with 400 mL of water at 25°C, it
takes approximately 15 minutes to bring the water to a full, rolling
boil.
Can I use a metal tray on top of my Corning
Q
No. The metal will act as a heat sink, and have a high probability of
creating an abnormal heating condition. If an abnormal condition is
detected, the product will shut down. A metal vessel will also scratch
the ceramic top plate.
The stir bar keeps decoupling. Why and what can I do to stop this?
Q
These units are programmed to minimize decoupling. However, liquid
viscosity, stir bar magnetic strength, vessel used, and speed changes can
cause decoupling. High viscosity liquids must be stirred at slower speed
settings. The magnetic strength of stir bars can weaken over time and
may need to be replaced. Vessels used need to have thin, flat bottoms
to insure optimal performance. Rapid decreases in stir speed can cause
decoupling as the magnet slows down quicker than the stir bar and the
liquid.
What size vessel should I use?
Q
Vessels used on the top of a hot plate must not be larger than the
top plate.
