PRODUCT INFORMATION
The Boekel series of Pipet Dryer and Combination
Washer/Dryer are manufactured from top quality
stainless steel and are designed to provide
automatic washing and heat drying of glass pipets
up to 375mm long. The series consists of a Pipet
Dryer only unit and a Pipet Washer/Dryer unit that
combines both the washing and drying functions.
Model 137100 & 137100-2 that provide washing
capability can be hooked directly to the lab faucet
(with user supplied hose) or permanently connected
to the lab’s water supply. This model is designed
with a natural “air gap” in the incoming water fill
tube to prevent back siphoning into the water
supply.
The models that provide electrical heat drying
capabilities are available in both 115 VAC and 230
VAC versions.

SETUP AND OPERATION OF PIPET DRYER
(Models 1372 and 1372-2)
1. Place the unit on a level surface and insert the
power cord plug into a grounded receptacle of
appropriate voltage.
2. For efficient operation, begin Pipet Dryer warm
up while pipets are being washed. To start the
Pipet Dryer, move the toggle switch to the “ON”
position. The red pilot light should illuminate.
3. Allow wet pipets to drain before placing them
into a hot dryer. Place pipets tip down into the
Pipet Dryer. An optional pipet holder (model
13741/2) is available for transferring pipets and
holding pipets in the dryer.
4. Drying time will vary, depending on quantity
and size of glassware. The approximate drying
time is one hour.
5. NEVER allow the Pipet Dryer to run overnight.
High temperature can build up and cause the
heater to burn out.
SETUP AND OPERATION OF PIPET
WASHER/DRYER (Model 137100 & 137100-2)
1. Place the unit on a level surface. A level
surface is required for the unit to operate and
drain properly. If a slanted drain board is used,
the unit must be built up on the low side so that
the unit sits level.
2. A 1/2" I.P.S. hose barb is supplied for
connecting the unit to a lab faucet with a user
supplied rubber hose. This hose barb may be
removed for alternate forms of water
connection. NOTE: Some states require the
use of an approved vacuum breaker in the
water supply line. Please consult your local
plumbing codes.
3. A 1” I.P.S. thread is provided on the drain port
to allow permanent connection of a drain line if
desired. Any such drain line must be capable
of handling the three gallons of water that are
instantly released during washing action. The
drain must not back up during water release.

4. Typical procedure for cleaning pipets: Load
the pipets into the pipet holder supplied with the
unit. Then, using a glass 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.
