Maintenance
Overview
StatSpin recommends that instrument operators perform periodic inspections and preventative
maintenance on all StatSpin instruments. Contact StatSpin’s customer service department or
distributor if, at any time, the instrument is not functioning properly.
CAUTION - Unplug the CritSpin from the wall outlet before performing maintenance.
WARNING - Do not expose CritSpin and its rotor to strong or concentrated acids,
bases, esters, aromatic or halogenated hydrocarbons, ketones or strong oxidizing
agents.
Cleaning
The outside surfaces and switch overlay panel can be cleaned with a water-dampened cloth and
mild detergent. The inner surface or bowl, a powder coated steel surface, can be cleaned with a
mild detergent and disinfected if necessary by wiping with a cloth dampened with 70% alcohol or
10% bleach.
CAUTION - DO NOT spray the bowl or outer surfaces with detergent or bleach.
Excess liquid will harm the electronics and subsequent problems may not be covered
under warranty.
Checking the Rotor Speed
The rated speeds can be checked with a photoelectric tachometer available from many sources. If
the CritSpin fails to achieve operating speed 16,000 rpm (
+ 250 rpm) contact your distributor or
StatSpin Customer Service department.
Replacing the O-Ring
The figure on the left illustrates the position of the rubber O-Ring which is attached to
the rotor-holder. Should it ever break a new one can be installed as shown, by
weaving it behind and in front of the 6 pins on the rotor-holder.
The points which the O-Ring touches the rotor are indicated by the letter “A”. Extra O-
Rings have been included.
