Safety Notes and Warnings
!
Once the probe attains appropriate viscosity, cylindrical
tube (Order no. 222- -1394) protectors that prevent
probe's radial exit must be used when measuring. An
operational error when using the measuring device can
lead to the probe's radial exit from the measuring gap; it
is therefore recommended to wear protective goggles.
!
Do not operate the unit with wet or oily hands.
!
Do not immerse the unit in water or expose it to spray
water.
!
Do not clean the unit using solvents (fire danger!) - - a
damp cloth applied with a household cleaning sub-
stance is often sufficient.
!
Complete separation from the mains is required when
repairs or maintenance work is about to be carried out.
!
Suitable personal protective gear, consisting of lab
coat, protective eyewear and safety gloves, must be
worn at all times when working with the instrument
!
Repairs, alterations or any work involving opening up
the unit should only be carried out by specialist person-
nel. Considerable damage can be caused by incorrect
repair work. The Thermo Fisher Scientific service depart-
ment is at your disposal for any repairs you may require.
!
Have the unit serviced by specialists at regular inter-
vals.
!
RheoStress1: The pressure of the air supply for the air
bearing must not exceed 4 bar. Higher pressure will
damage the air bearing permanently!
!
For applications at elevated temperatures above 250C
it is a must to switch the fan for the air bearing cooling
on stage 2 (on the rear) and use ceramic shafts only.
Furthermore use the cone heater TC1 as thermal shield
to prevent the heating up of the air bearing housing!
Severe skin burns can be caused by contact with hot
unit parts!
The rheometer can reach temperatures up to 350 C, depen-
ding on the temperature control unit installed. This can result
in parts of the rheometer heating up to such an extent, even
when taking the cooling and insulation into account, that se-
rious burns can result if they come into contact with the skin.
Thermo Fisher Scientific recommends shielding the rheome-
ter when operating at high temperatures and handling it only
with high temperature proof gloves and safety glasses.
A danger symbol on the glass plate warns the user of possi-
ble danger (burn injury).
