INTRODUCTION
Congratulations on your decision to purchase a TBS
®
6.25-Gallon Paraffin Dispenser.
Your instrument is designed to meet the large volume requirements of today's histology
laboratory by offering the convenience of having 6.25 gallons of molten paraffin
available at all times. While one low-wattage heating element remains on continuously
to prevent clogging within the spout, two other higher wattage elements are
microprocessor-controlled to maintain 1°C temperature accuracy within the paraffin
reservoir. A sensor positioned on the outside cylinder wall detects temperature
changes precipitated by the introduction of solid paraffin pellets. A complex software
algorithm immediately responds by increasing the temperature of heaters at the bottom
of the cylinder and/or surrounding the cylinder wall. As the pellets melt and the
temperature approaches the set point, the software cycles both elements on or off as
required to maintain the set point. A safety overheat protector device (88°C) is
appropriately positioned to provide additional security.
