Overview
The OxiTop
®
Box serves to regulate the temperature of samples on a stirring
platform, for the determination of the biochemical oxygen demand according to
the self-monitoring procedure. The OxiTop
®
Box is especially suitable for the
inductive stirring platforms IS 6, IS 12 and IS 602, and to incubate samples
according to the BOD DIN procedure.
The thermostat box is heat insulated and made of stainless steel 1.4301,
including the interior. The deep-drawn plastic cover hood can easily be opened
and grants simple and comfortable loading. Inside the box, beside the cold
evaporator with condensate tub, there is a storing area for 6 methylene blue
samples.
A crossflow blower provides permanent air circulation. The temperature is con-
trolled by a precision control system which activates the heating or refrigerating
system. The refrigeration cycle is hermetically sealed and contains evaporator,
condenser and an automatically ventilated refrigerating unit. The automatic
defroster provides constant refrigerating power.
The power supply of the used stirring platform is provided via the socket inside
the box.
To determine BODn and oxygen consumption, a constant tempera-
ture of 20°C ± 1 °C is required.
