Brookfield viscosity is a simple viscosity value obtained with a Brookfield Viscometer, usually fitted with a dip-in spindle but may also be fitted with some specialist accessories such as Cone/Plate, Helipath stand and T-Bar spindles or a concentric cylinder measuring system such as a Small Sample Adaptor or Ultra-Low Accessory.
An ideal Brookfield viscosity value quoted in a specification should also state the instrument and measurement conditions:
- Torque range: In order of increasing torque (and hence viscosity) range: LV, RV, HA or HB. The torque range usually prefixes the model number, for example: RVDVI+ or LVDVII+.
- Spindle e.g. RV2, LV3, T-C Speed of rotation: 10rpm etc
- Measurement temperature
Sometimes the following information would also be necessary:
Container size
- For example DVI+, DVII+ etc
- Measurement time
- Sample pre-conditioning instructions
Model of viscometer:
So a typical spec may look like:
Brookfield LVDVII+, spindle 3 at 20rpm, 25°C, take measurement after 30s.
