The ConductScience Vacuum Aspiration System provides laboratory-grade vacuum suction for liquid waste removal and sample aspiration across research applications. The system combines a 4L waste collection bottle with precise vacuum control ranging from 0 to 600 mbar, delivering maximum aspiration speeds of 17 mL/s for efficient liquid handling. The compact benchtop design operates at noise levels ≤55 dB, making it suitable for sensitive laboratory environments requiring minimal acoustic interference.
The system features autoclavable components including tubing, waste bottle, and operation handle, supporting sterile technique protocols in microbiology and cell culture applications. Universal power supply compatibility (100-240 VAC, 50/60 Hz) and the lightweight 3 kg construction facilitate laboratory placement and relocation as experimental needs change.
How It Works
The vacuum aspiration system operates through mechanical vacuum generation, creating negative pressure within the 4L collection bottle to draw liquids through connected tubing. The vacuum range of 0-600 mbar provides precise suction control for different liquid viscosities and aspiration requirements, while the maximum flow rate of 15 L/min (air) ensures rapid evacuation without system overload.
Liquid aspiration occurs when the vacuum differential overcomes surface tension and gravitational forces, allowing controlled removal of solutions from containers, surfaces, or experimental setups. The 17 mL/s maximum aspiration speed accommodates rapid liquid handling while maintaining sufficient control for delicate procedures. The system's low noise operation (≤55 dB) minimizes acoustic interference with sensitive laboratory equipment and personnel comfort during extended use periods.

This system combines a large 4L waste capacity with precise vacuum control (0-600 mbar) and rapid aspiration capability (17 mL/s). The autoclavable components and quiet operation (≤55 dB) address sterile technique requirements and laboratory acoustic considerations that are often limitations in comparable vacuum aspiration systems.
Practical Tips
Verify vacuum pressure readings quarterly using a certified reference gauge to ensure accurate pressure control across the 0-600 mbar range.
Why: Accurate vacuum levels are critical for consistent aspiration performance and reproducible experimental conditions.
Inspect and replace aspiration tubing every 3-6 months or when flexibility decreases, as hardened tubing reduces aspiration efficiency.
Why: Degraded tubing creates vacuum leaks that compromise system performance and aspiration speed.
Position the aspiration tip near the liquid surface rather than submerging deeply to minimize bubble formation and maximize aspiration control.
Why: Surface aspiration reduces turbulence and prevents accidental aspiration of settled material or cell pellets.
Never aspirate volatile organic solvents or corrosive chemicals without verifying tubing compatibility and ensuring adequate ventilation.
Why: Incompatible chemicals can degrade tubing materials and create safety hazards through vapor accumulation.
If aspiration speed decreases, check for clogs in the aspiration tip and verify all tubing connections are leak-tight.
Why: Reduced performance typically results from airway obstructions or vacuum leaks that impair system efficiency.
Record aspiration volumes and vacuum settings in laboratory notebooks to maintain procedural consistency across experimental replicates.
Why: Documented aspiration parameters enable method validation and troubleshooting when experimental results vary.
Empty the waste bottle when 80% full rather than waiting for complete filling to prevent overflow and maintain optimal vacuum performance.
Why: Overfilled bottles reduce available air space needed for effective vacuum generation and liquid handling.

Compliance
What types of liquids can be safely aspirated with this system?
The system handles aqueous solutions, culture media, and most laboratory solvents. Avoid aspirating corrosive acids, strong bases, or volatile organic compounds that could damage tubing or create safety hazards. Consult the chemical compatibility chart in the user manual for specific solvents.
How do I maintain sterility when working with cell cultures?
Use the autoclavable components (tubing, waste bottle, operation handle) sterilized at 121°C for 15 minutes. Replace aspiration tips between samples and work within a laminar flow hood to prevent contamination during aspiration procedures.
What is the minimum liquid volume that can be effectively aspirated?
The system can aspirate volumes as small as 100 μL, though aspiration efficiency depends on liquid surface tension and container geometry. Use appropriate tip sizes and aspiration angles for optimal small-volume handling.
How often should the waste bottle be emptied and cleaned?
Empty the 4L waste bottle when 80% full or at the end of each working day. Clean with appropriate disinfectants based on aspirated materials, and autoclave if used with biological samples.
Can the vacuum level be adjusted during operation?
Yes, the system provides variable vacuum control across the 0-600 mbar range. Adjust vacuum levels based on liquid viscosity and aspiration requirements, using lower pressures for delicate cell work and higher pressures for viscous solutions.
What maintenance is required for consistent performance?
Replace aspiration tubing every 3-6 months or when showing wear, clean waste bottles after each use, and inspect seals quarterly. Lubricate moving parts annually and calibrate vacuum pressure annually using certified standards.
Is the system compatible with different tube and tip sizes?
The system accepts standard laboratory tubing connections. Use appropriate adapter fittings for different tip sizes, ensuring leak-tight connections to maintain vacuum integrity and aspiration performance.
