Boekel Scientific 137100-2 Pipet Washers - Manual (Page 2)

4. Typical procedure for cleaning pipets: Load
the pipets into the pipet holder supplied with the
unit. Then, using a pyrex jar, soak the pipets in
a Dichromatic acid solution up to 50% in
strength. Allow pipets to drain when removing
them from the Dichromatic solution, and then
place them immediately into the Washer or
Washer/Dryer unit and turn on the water to
initiate the washing action.
5. Care should be taken to minimize the amount of
acid solution that drips into the Washer or
Washer/Dryer as acids can have a detrimental
effect on the units.
6. The complete washing cycle of filling the unit
with water and draining is accomplished in
approximately 70 seconds, depending on the
incoming water flow. It is recommended that
water flow be set at about 2 to 3 gallons per
minute for good washing action. Ten to fifteen
washing cycles with hot water are
recommended for best washing action. Cold
water however can be used.
7. To initiate the drying cycle on Washer/Dryer
models 137100 and 137100-2: insure that the
water for the washing cycle has been shut off
and that the water has fully drained from the
unit.
8. The wet pipets from the washing cycle should
be drained outside the Pipet Washer/Dryer
before beginning their drying. Pipets should be
in tip down for best drying results.
9. Insure that the unit’s power cord plug has been
inserted into a properly grounded outlet of
appropriate voltage.
10. Activate the dryer heater by moving the toggle
switch to the “ON” position. The red pilot light
should illuminate.
11. Drying time will vary, depending on quantity and
size of glassware. The approximate drying time
is one hour.
12. When drying is complete, switch the unit “OFF”
and allow the unit to cool for 30 minutes before
beginning the next washing cycle.
13. NEVER allow the drying cycle to run over night.
High temperature can build up and cause the
heater to burn out and cause possible solder
gaps resulting in leaks.
CLEANING
All Pipet Washer/Dryer and Dryer models can be
internally rinsed with clean water and wiped
externally with a damp cloth. The Pipet Dryer and
Washer/Dryer models must be unplugged before
any cleaning is performed. The pipet holding rack,
when used, should always be rinsed if it was used
in acidic solution.
