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.

Trap

Vacuum

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.
