Looking for unparalleled performance and safety when aspirating fluids in the lab? Take a look at our aspiration systems.

MIDSCI offers several laboratory aspirators that can fulfill your requirements.
In particular, we carry the ASPIRE laboratory aspirator.
This is a quiet, compact, aspirator with adjustable vacuum pressure that has a maintenance-free pump inside a sturdy base.
Among other things, the ASPIRE aspiration system comes with an antibacterial/hydrophobic filter, silicone tubing, as well as a 2 liter, polycarbonate collection bottle that’s autoclavable and break resistant.
This laboratory aspirator is perfect for the removal of media from tissue culture vessels or plates.



Aspirating Pipets

  • Ideal for aspiration of media and sample waste removal
  • Supplied without graduations or plugs


  • Compact Design
  • Built-in Vacuum Pump
  • Adjustable Vacuum Pressure
  • Vacuum Gauge
  • Safe and Precise Aspiration

The Accuris ASPIRE Laboratory Aspirator incorporates a quiet, maintenance-free pump inside a sturdy, yet compact base. The vacuum is fully adjustable, with a pressure gauge that displays the vacuum level, allowing full control of aspirating speed. The ASPIRE is an ideal choice for a wide range of laboratory aspirating applications, including removal of media from tissue culture vessels or plates, and supernatants. An ergonomic, hand held aspirating device is included, and holds standard 200 to 300ul disposable pipette tips.

Comes complete with:

  • Base with internal vacuum pump
  • 2 Liter, Polycarbonate Collection Bottle (autoclavable and break resistant)
  • Antibacterial / Hydrophobic Filter
  • Silicone Tubing
  • Handheld Vacuum Controller
  • 2 Pipette cone adapters (for 200 ul pipette tips and 40mm stainless steel)

The collection bottle incorporates a reliable Overflow Protection Valve that closes off the tube to the vacuum in the event of a full bottle. In addition, the replaceable in-line filter protects the vacuum pump from contaminants and any moisture that comes through the bottle. Graduations on the collection bottle indicate the amount of fluid collected and when it's ready to be emptied. The Handheld Vacuum Pipette has an ergonomic design that's comfortable in the hand during prolonged use.  Pressing the button applies the vacuum. The pipette accepts Pasteur pipettes, serological pipettes, and also comes with 2 accessory pipette cones. One cone is designed to accommodate 200/300ul pipette tips, the other has a thin, stainless steel capillary for fine control aspirating.

The Wheaton OmniSpense ELITE and UniSpense PRO are intelligent peristaltic pumps for all your dispensing needs. Whether you are making sterile liquid trasnfers to and from containers or filling vials or titer plates, these pumps will simplify and accelerate your laboratory output.

The systems are operated via a large 5" backlit liquid crystal display and chemical resistant keypad. Options are displayed as large icons for quick operation and easy recognition in national and international markets. The pumps also feature a small footprint and an angled polarized display perfect for use under a fume hood or biological safety cabinet.

Calibration of the units is simplified to a single intuitive calibration screen that walks the user through the process stepwise. This eliminates scrolling through menus and complicated instruction manuals.

The OmniSpense ELITE and UniSpense PRO can be specifically outfitted and programmed for your process. These programs can be saved and recalled at a later time for a quick application turnaround. Both pumps support tubing with different specificaitons and the OmniSpense ELITE can use stacked pump heads or microcassette heads for multiple small volume dosing.

The UniSpense PRO is a dual-speed dedicated dispensing pump designed to accommodate single of multiple filling applications. The OmniSpense ELITE is a variable speed dispensing pump with built-in FLOW mode. The FLOW mode allows for real time tracking of a single liquid transfer. The pump can be paused and restarted for more involved processes.

The OmniSpense ELITE and UniSpense PRO help menus are English, Chinese, French, Japanese, Korean and Spanish language enabled. These menus ensure the icon driven display is easily understood by national and international laboratories.

The OmniSpense ELITE and UniSpense PRO are ideal for any laboratory or clinical setting where accurate and precise dispensing is important.
