Heating Mantle; Dewar Support - Micromeritics FlowSorb III 2305 Operator's Manual

FlowSorb III

Heating Mantle

A heating mantle is installed on a sample tube only when in the Degas position.
Its purpose is to maintain the specified temperature (specified using the Temp
Set dials). The mantle is slid upward about the sample tube and held in place
with a flared U-clamp. Refer to Chapter 2 for instructions on properly installing a
heating mantle.

Dewar Support

A Dewar of cooling liquid around the sample tube is required to initiate gas
adsorption.
• FlowSorb III 2310: The Dewar tray is directly below the sample analysis
port near the base of the instrument platform. The Dewar is placed on the
tray. The tray rises automatically when the analysis is started, inserting the
sample tube into the cooling liquid within the Dewar. The tray lowers for
removal of the Dewar automatically after adsorption data are collected. No
operator involvement is required.
• FlowSorb III 2305: The Dewar is supported by a hinged platform. The
platform hangs down when not in use. The Dewar is manually brought up
around the sample and the platform swung upward where it locks into
place. The Dewar is removed by holding the Dewar with one hand and
pressing the Release button to the right of the platform. This causes the
platform to drop out of the way, allowing you to remove the Dewar.
When the platform is raised, the instrument automatically collects adsorption data.
When it is down, desorption (or evaporation) data are collected. There is no
need, nor other means provided, to select between adsorption and desorption data.
