a. Type TR spindles are the optional spindles for use with the Adaptor for Small Sample Volumes; See "Spare
parts and accessories" on page 28.
b. The minimum recommended reading is 15% of the full scale value.
c. TR8 shear rate: 0.93 x rpm with sample volume of 8.0 cm³
d. TR9 shear rate: 0.34 x rpm with sample volume of 10.5 cm³
e. TR10 shear rate: 0.28 x rpm with sample volume of 11.5 cm³
f. TR11 shear rate: 0.25 x rpm with sample volume of 13.0 cm³
The Shear Rate (S.R.) has been calculated assuming the characteristics of newtonian products.
