Brookfield Viscosity Standard Fluid - General Information
We recommend that Brookfield Viscosity Standard Fluids be replaced on an annual basis, one year
from date of initial use. These fluids are either pure silicone or mineral oil and are not subject
to change over time. However, exposure to outside contaminants through normal use requires
replacement on an annual basis. Contamination may occur by the introduction of solvent, standard
of different viscosity or other foreign material.
Viscosity Standard Fluids may be stored under normal laboratory conditions. Mineral oils should
be stored in the container in which they are supplied. Disposal should be in accordance with state,
local and federal regulations as specified on the material safety data sheet; MSDS information is
available upon request on our website to down load.
Brookfield Engineering Laboratories does not recertify Viscosity Standard Fluids. We will issue
duplicate copies of the Certificate of Calibration for any fluid within two years of the purchase date.
Brookfield Viscosity Standard Fluids are reusable provided they are not contaminated. Normal
practice for usage in a 600 mL beaker is to return the material from the beaker back into the
bottle. When using smaller volumes in accessories such as Small Sample Adapter, UL Adapter,
Thermosel or Spiral Adapter, the fluid is normally discarded.
Calibration Check Procedure for LV (#1-3) and RV,HA,HB (#1-6) Brookfield Spindles
NOTE:
The LV #4 (#64) and the RV, HA, HB #7 spindle have been omitted from this
procedure. Brookfield does not recommend the use of these spindles to perform
a calibration check on your instrument. Reasons pertain to the small amount of
spindle surface area that makes contact with the viscosity standard, the difficulty
of establishing the immersion mark precisely and the need for precise temperature
control at 25°C in the immediate vicinity of the spindle.
