How to easily handle liquid waste with a vacuum aspirator

Managing liquid waste with a vacuum requires a sturdy pump, strong hoses, and a solid container. Check that every link is correct, and then move the sealed containers safely to the trash area.

Working with liquid waste in a lab requires accuracy and carefulness. This is key to handling waste properly and safely, especially when the liquids are biological, chemical, or radioactive.

Traditional methods usually use vacuum pumps to get rid of the liquids. However, vacuum aspirators, like the aspirator system, form a new, smart, and easy-to-use substitute.

Why Use a Vacuum Aspirator?

Many labs find vacuum aspirators easy to use because of their flexibility and simplicity. They outperform tasks like cell culture, pulling RNA/DNA, removing micro plate waste, separating liquids from solids, or returning liquids.

Advantages of Using a Vacuum Aspirator

1. Performance:

Devices like the aspirator system, a type of vacuum aspirator, ensure steady and forceful suction. This is key for effectively dealing with liquid waste.

2. Simple to Operate:

These devices are easy to use, with little assembly and plain instructions.

3. Small Setup:

The aspirator’s model is small and all-inclusive. It doesn’t hog space and quickly fits into any lab.

4. Secure:

Vacuum aspirators require precautions for safety. They help manage dangerous waste safely, reducing exposure or contamination chances.

Setting Up the Aspirators System

a)     Assembly

The aspiration machine is built for a simple setup.

Follow this guide to get your system ready:

      Piece Together the System: The unit arrives with a few components. To put together the parts, follow the user manual.

      Hook up the Pipes: Fix the pipes to the cap, the suction device, and the main unit. Make sure every connection is tight to stop leaks.

      Turn On: Insert the main module plug into a power outlet and flip the power button at the back of the device to “ON.”

b)     Using the Machine

While using the machine, check the suction force for liquid waste

      Adjust the Suction Force: Twist the suction regulator knob to the right to fix the suction force as required. The signal lights will become stable once the machine is at the defined suction level.

      Activate Suction: Press the control button on the hand tool to start the suction. To use it continuously, shift the latch to the highlighted spot.

Upkeep and Cleaning

Regular cleaning of your aspirator machine is significant for its effective working and long-lasting use.

The breakdown for Cleanup

1. Cut Power:

Always ensure the base unit is unplugged from the power source before cleaning.

2. Detach Tube:

Pull out the Tube from its connection points – cap, suction handle, and base unit.

3. Decrease Pressure:

For the 4L mode l, twist the air vent valve in the opposite direction of a clock-hand movement to ease the pressure (or take off the vent cap if using the 2L version).

4. Cap Off:

Lastly, pull off the cap from the dirt collection container.

Tips for Unit Cleaning  

1. Housing Cleanup:

Grab a lint-free cloth, and douse it lightly with either a mild soap water mixture or 70% isopropanol or ethanol solution. Avoid potent detergents or harsh chemical solvents.

2. Autoclave for Contact Parts:

Any part touching fluids, including the waste collection container, cap with tube connectors, silicone pipes, and hand device, should be autoclaved.

3. Filters Demand Attention:

Regularly change out the waterproof filter, preferably every 90 days. Replace it right away if it gets wet.

4. Hazardous Material Cleanup:

Are you working with solvents or hazardous stuff? Clean your hand device and tubing with water. Afterward, rinse them with 70% ethanol.

Routine Maintenance

The aspirator system is low-maintenance. If the suction power drops, it could be because of a clog in the tubing or filter. It’s easy to fix; swap the clogged d tube or filter.


The aspirator system, a type of vacuum aspirator, speeds up lab work. It’s ideal for many jobs because it is safe, efficient, and easy to use. If you pay attention to setting it up properly, using it correctly, and keeping it in good shape, you can count on the aspirator. It can be a trusty sidekick for handling liquid waste, turning a complicated task into a simple one.
