Solution reservoir heating is an important
technique used to eliminate outgassing in heated
solutions. Since the gas load of a solution is
dependent on pressure and temperature,
preheating a solution at atmospheric pressure
prior to delivery to a warmed environment will
minimize the occurrence of bubbles in the bath,
even if the solution is allowed to cool en
The Syringe Warmer System from Warner
Instruments is comprised of the SW-707
Syringe Heater Controller, a PS-560 Syringe
Heater Stand and up to six SW-60 Syringe Heaters.
Each SW-60 accommodates a
single 60 cc syringe. This system has been
optimized to provide accurate regulation of
solution temperature during preheating.
The temperature of a syringe heater can be
set by either local or global control. Local
control is selected by setting the associated
channel MASTER/LOCAL toggle switch to local on
the SW-707. In either local or
global mode, the LED on the syringe warmer will
cycle in parallel with the associated LED on the
When used in the local mode, the SW-707
allows the temperature of each syringe block to
be independently set. A master mode allows all
syringe blocks to be set to the same temperature.
Both the set temperature and the actual
temperature of each syringe block can be
displayed on the LED meter.
