1.0 Product Description
The Corning® Aspirator is an aspiration device
used for the removal of liquids from a variety of
lab vessels. It is designed for use with an in-house
vacuum system. The aspirator allows precise
fingertip control of aspiration and presents a
sensible alternative to the use of glass pipets for
supernatant disposal.
Designed for a comfortable fit in either hand,
the aspirator can be used with a variety of
collection devices. These include some glass
pipets, 2 mL plastic pipets (Cat. No. 4020, 4021,
4486) or 2 mL aspiration pipets (Cat. No. 9186).
Included with the aspirator is a single-channel
adapter (Cat. No. 155850) for use with standard
1 to 200 µL disposable pipet tips (Cat. No. 4804,
4860, 4864), as well as a rubber adapter for glass
pipets (Cat. No. 155505).
An 8-channel adapter for standard 1-200 µL
disposable pipet tips is available for use with
96-well microplates.

Source
The aspirator is designed for use with a vacuum
pump or an in-house vacuum system and a
suitable collection vessel.
Connect the hose barb end of the aspirator
handpiece to flexible 4 mm I.D. thick wall (to
prevent collapsing under vacuum) silicone
rubber tubing, and then connect the other end
to a suitable collection vessel. These heavy wall
filter flasks have a protective PVC coating that
helps prevent the glass from shattering. They are
autoclavable (121°C) and resistant to thermal
shock. The collection vessel is then connected
by tubing to the vacuum source. NOTE: When
working with infectious materials, connecting a
second vessel or 50 mm hydrophobic membrane
disc filter (Cat. No. 431227) as an in-line safety
trap between the collection vessel and the vacuum
source is strongly advised.
The aspirator is supplied with a soft rubber
grommet which holds both glass and plastic
2 mL pipets. To use the single-channel pipet tip
adapter, simply remove the orange fastening
sleeve from the aspirator handpiece by turning
one-quarter turn counterclockwise, take out
the rubber grommet, and replace with the tip
adapter, which has its own fastening sleeve.
Tighten with a clockwise one-quarter turn.
To connect the 8-channel adapter for disposable
tips, remove the fastening sleeve and rubber
grommet, and replace with the 8-channel adapter
which has its own fastening sleeve.

4.0 Aspirator Operation
Vacuum pressure through the aspirator is
controlled by the pressure-sensitive orange control
button on the top of the handpiece.
Using the plastic screw opposite the control
button, you can set a residual vacuum level to
prevent waste liquids dripping from the tip or
the pipet. The aspirator is factory preset to allow
a low level of constant suction; by turning the
screw one full turn clockwise, the valve is shut
and residual vacuum is stopped.
5.0 Cleaning and Service
The aspirator is entirely autoclavable. When
working with biohazardous material, sterilize the
unit before disassembling for cleaning. Refer to
the diagram (below) for disassembly.
To clean, immerse the pieces in mild laboratory
detergent, but do not use abrasives, as a rough-
ened surface may affect the smooth operation of
the control valve. NOTE: When working with salt-
rich solutions, rinse out the aspirator handpiece
with distilled water after use to avoid build-up of
dried deposits.
Apply a thin coat of Dupont Molykote® BG-87
lubricant as needed to the control valve to keep
the action smooth.
