Chemglass’s Digital Dry Baths are highly accurate, microprocessor controlled, dry block heating units capable of heating one, two or
four aluminum blocks or aluminum or glass pans. They provide unsurpassed temperature uniformity and accuracy for heating
microtubes, test tubes and other small vessels, including microplates and slides. Each dry bath has a bright green LED display, easy
to set temperature and time controls and comes complete with a block lifter.

CAUTION: Hot surfaces, especially on the block, can cause serious injury or burns.
CAUTION: Do not put water or liquids into the well as shock, serious injury and death may occur.
CAUTION: Do not heat flammable or explosive substances as serious injury and death may occur.
SET UP and OPERATION
Place the dry bath on a stable, flat surface away from air vents and any equipment exhaust vents. Plug the dry bath into a properly
grounded outlet of the correct voltage. Insert the block(s) into the heating well using the block lifter. Caution: blocks may be hot!
Using the switch on the back of the unit, turn the power on. The dry bath will make a “beep” sound, illuminate each digit on the
display left to right and briefly illuminate the LED lamps while it performs a unit test. After the unit test, the display will begin showing
the block temperature and the unit will begin heating the block to the previously set temperature and flashing the Heating lamp.
Setting the Temperature
Use the Up and Down arrow buttons to increase or decrease the temperature setting. The temperature can be set in tenths of a
degree C. Once the temperature is set, the display will then revert to showing the block temperature and the Heating lamp will flash
until the set temperature has been reached. The temperature setting is automatically remembered if power is turned off or if the
power is lost.
Using and Setting the Timer
The dry bath has a built-in, independent, digital timer function that sounds a “beeping” alarm when the set time has been reached.
The timer is completely independent of the heating function and does NOT turn off the heater when set time is reached. This allows
the Timer to alert the user that the time setting has been reached but does not disturb samples being heated. (continued on next
