Procedure
The bleach solution is caustic; wear gloves and eye
protection when handling the solution.
Do not immerse the instrument, spray it with liquid, or use a
“wet” cloth. Do not allow the cleaning solution to run into
the interior of the instrument. If this happens, contact the
Bio-Tek Service Department.
Do not soak the keypad—this will cause damage.
Important!
Turn off and unplug the instrument for all
decontamination and cleaning operations.
1. Turn off and unplug the instrument.
2. Prepare an aqueous solution of 0.5% sodium hypochlorite (NaClO, or
bleach). As an alternative, 70% isopropyl alcohol may be used if the effects
of bleach are a concern.
Be sure to check the percent NaClO of the bleach you are using; this
information is printed on the side of the bottle. Commercial bleach is
typically 10% NaClO; if this is the case, prepare a 1:20 dilution.
Household bleach is typically 5% NaClO; if this is the case, prepare a
1:10 dilution.
