DAPTERS
Heating stations, sample tubes, and heating station adapters may be very hot.
n
Wear the proper gloves and hold the sample tube by the upper part of the stem.
n
If the adapter has a handle, hold the adapter by the handle.
n
Do not place fingers inside the heating stations. The stations may be very hot.
n
Do not place adapters near any combustible material or touch them with fingers.
n
Do not place a hot adapter on a unprotected surface such as a countertop. The
adapter may burn the surface.
n
Failure to observe these precautions may result in severe burns.
Heating station adapters are included in the accessories kit for use with sample tubes. There are
three models of heating station adapters. Use the appropriate model as shown in the
Heating
Station Adapters
table. Additional adapters can be ordered from Micromeritics.
The adapters used with Gemini sample tubes may remain in the stations until a different type of
sample tube is needed.
The adapters used with the TriStar and ASAP Series sample tubes must be removed when the
sample tube is removed. The adapter may be stored in the heating station or in a cooling rack.
Adapters constitute an isothermal shield and help to maintain uniform temperature throughout the
sample bed. Sample temperature, however, depends on several factors:
n
The thermal conductivity of the sample material
n
The quantity of sample material
n
The rate of gas flow through the sample bed
All materials do not heat identically. The actual sample temperature can be expected to be within
±10 ºC of the current temperature (PV) displayed on the temperature controller. If an exact sample
temperature is critical to the application, measure the sample bed with a temperature probe and
adjust the set point temperature accordingly.
