All standard RV, HA or HB torque Brookfield Ametek Viscometers/Rheometers are supplied with a standard spindle set (RV-2 through RV-7) constructed of #302 stainless steel. Additional spindle options are available in #316 stainless steel or Teflon coating for increased corrosion resistance.

An optional spindle rack makes a convenient storage "bench" and allows easy and quick access to all spindles.

EZ-Lock spindles with a special coupling system are also available. This option allows spindles to be quickly attached and removed, and may also help prevent against damage that can occur from frequent spindle changes or multiple users. Spindles can only be used with instruments purchased with EZ-Lock option or ones that have been retrofitted.
