ScrubAir

Pipette Washer/Dryers

ScrubAirTM Pipette Washer/Dryers

FAST, THOROUGH CLEANING WITH PERCOLATING ACTION

e ScrubAir is automated, easy to use and requires less glassware handling than traditional methods. Less handling
reduces the risk for glassware breakage and possible injury.

he ScrubAir Pipette Washer/Dryer uses water,

detergent and compressed air to wash, rinse

T

and dry volumetric pipettes. is automatic
washer/dryer can accommodate pipettes ranging in
size from 0.135" (3.4 mm) stem diameter and 7.5"
long up to 0.34" (8.6 mm) stem diameter and 25"
(635 mm) long. Depending on the bulb and stem
diameters, up to 60 small or 12 large pipettes may
be washed at one time.

e ScrubAir works by directly injecting water and
detergent into the interior of the pipettes. While in
the bulbs of the pipettes, the compressed air intro
duced into the water line produces a percolating
action that scrubs the interior walls. e water is
then propelled out the top of the pipettes, hitting
the top of the clear cover and cascading down. As
the water cascades down, it washes the exterior of
the pipettes. Each wash cycle repeats this percolat
ing/cascading process to achieve thorough cleaning

e ScrubAir processes up to 60 pipettes at one time. Depending on number of pipettes processed using a siphoning method, time and water savings
calculations may vary.
*Based on a 4 hour wash at a ow rate of 2 L/min., 2 hour pure water rinse at 1 L/min. and overnight drying in a oven. Since drying is typically
done overnight, the amount of time may be substantially higher than noted in this example.
**Based on tap water cost of $0.0003/L and deionized water cost of $0.09/L.

inside and out. For each rinse cycle, this same
percolating/cascading action is used. Aer washing
and rinsing, the ScrubAir dries the pipettes in two
to eight hours. No separate oven is required.

Compared to traditional siphoning washing/rins
ing and oven drying, the ScrubAir consumes less
water, time and money. Table 1 shows Time and
Water Usage of a traditional siphon washing and
rinsing/oven drying protocol and a comparable
washing and drying program using the ScrubAir
with heater option. As this example illustrates, the

-

ScrubAir requires 3 1/4 hours to wash, rinse and
dry as many as 60 pipettes compared to 23 hours
or more with the traditional method. Eco-friendly,
the ScrubAir Standard Wash Cycle uses only 12.5
liters of tap/pure water compared to 600 liters used
with a siphoning method. Using less water results

-

in an annual water cost savings of over $2900.

Features & Benefits

•

oroughly cleans volumetric

pipettes inside and out. Percolat-
ing action of compressed air and
water scrubs the interior walls
while water and detergent cascade
down the outside walls.

•

Dries quickly with compressed air
in about four hours compared to up
to 17 hours with traditional overnight
oven drying. Models with built-in
heater dry twice as fast—two hours.

•

Accommodates from 12 to 60
pipettes depending on bulb and
stem diameters. See back cover for
pipette capacity details.

•

Saves water and money. Compared
to traditional siphoning methods
that can use over 600 liters per load,
the eco-friendly ScrubAir uses as little
as 12.5 liters of tap/pure water, which
adds up to water savings costs of
$2900 or more.

•

Reduces pipette inventory needs.
Since the ScrubAir washes and dries
in about one fourth the time spent
using traditional methods, less
glassware may be kept in reserve.

•

Programmable. Factory cycle settings
(wash, rinse and dry times and
number of rinses) may be user
modied. Start time may be delayed
up to 8 hours to take advantage of
o-peak hours.

•

Less glassware handling required,
reducing the risk of breakage and
personal injury. Load once for
washing, rinsing and drying. No
transfer needed to a separate oven
for drying.

•

Portable. Quick connect coupling
allows the ScrubAir to be hooked
to a sink faucet. When placed on
a cart, it may be easily transported
from lab to lab. (Or, if preferred,
it can be installed using a dedicated
water supply and drain.)
