1. INTRODUCTION.
1.1. The
Electrothermal
range of Electric Bunsen’s have a high temperature heat
source designed for general purpose laboratory use. They are suitable for the non
-
contact radiant heating of materials in test tubes, crucibles, small flasks and beakers.
1.2. Each Bunsen radiant heater bowl is constructed within a robust, corrosion resistant
cylindrical stainless steel housing. The replaceable heater assembly consists of a
coiled resistance heater. This in turn is formed around the outer surface of a ceramic
bowl. The heater assembly is then mounted in the top of the Bunsen’s cylindrical
housing. Air circulation / cooling vents are provided in the lower half of the Bunsen
housing
ensuring that the base remains cool enough to touch
whilst operational. A
detachable cowl is supplied with the Bunsen to deflect heat from the medium surface
when hand holding the Bunsen
(with heat-resistance gloves).
