Levo Plus Pipette Filler
Manual pipette filler for precise liquid aspiration and dispensing with glass and plastic pipettes in laboratory applications.
| Automation Level | manual |
The Levo Plus Pipette Filler is a manual liquid handling device designed for precise aspiration and dispensing of liquids in laboratory environments. This pipette filler provides controlled suction and dispensing capabilities for glass and plastic pipettes, enabling accurate volume transfers in analytical and preparative procedures.
The device features ergonomic design with manual operation controls for aspiration, dispensing, and blowout functions. With compact dimensions (9.5 × 25.5 × 24.0 cm) and lightweight construction (0.66 kg), the Levo Plus offers portability and ease of use across various laboratory applications requiring precise liquid handling.
How It Works
The Levo Plus Pipette Filler operates through manual control of air pressure and vacuum to facilitate liquid aspiration and dispensing. The device creates controlled suction through a manual pumping mechanism, allowing liquid to be drawn up into the pipette. A separate dispensing control enables precise release of the liquid by applying gentle positive pressure.
The three-function design typically includes aspiration (A), dispensing (S), and blowout (E) controls. The aspiration function creates vacuum to draw liquid into the pipette, the dispensing function allows controlled release of liquid, and the blowout function expels any remaining liquid from the pipette tip. This manual control system provides the operator with tactile feedback and precise control over liquid handling operations.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Operation Method | Manual three-function control system | Basic bulb or single-function manual fillers often provide limited control options | Enables precise control over each phase of liquid handling for improved accuracy and reproducibility |
| Weight | 0.66 kg lightweight design | Heavier models may exceed 1 kg | Reduces operator fatigue during extended use and improves portability between workstations |
| Power Requirements | No external power needed | Electronic alternatives require batteries or AC power | Provides operational flexibility in any laboratory location without power constraints |
| Maintenance Requirements | Minimal maintenance manual system | Electronic systems often require battery maintenance and electronic component servicing | Reduces long-term operating costs and minimizes downtime for maintenance procedures |
The Levo Plus combines lightweight portability with three-function manual control for versatile liquid handling operations. The manual operation provides tactile feedback and eliminates power requirements while maintaining precise control over aspiration and dispensing functions.
Practical Tips
Use slow, controlled movements for both aspiration and dispensing to minimize air bubble formation and ensure accurate transfers.
Why: Consistent technique reduces variability and improves reproducibility of liquid handling operations.
Clean the pipette attachment area after each use session and inspect seals regularly for wear or damage.
Why: Proper seal integrity is essential for maintaining vacuum and preventing contamination between samples.
Verify transfer accuracy periodically using gravimetric methods with distilled water at room temperature.
Why: Regular accuracy checks ensure reliable performance and identify any drift in transfer precision over time.
Always use appropriate pipette tips and never pipette directly from stock reagent bottles to prevent cross-contamination.
Why: Proper technique prevents sample contamination and maintains reagent purity for accurate analytical results.
If suction appears weak, check for air leaks at the pipette connection and ensure all seals are properly seated.
Why: Air leaks compromise vacuum performance and lead to inaccurate liquid transfers and poor reproducibility.
Pre-wet the pipette tip with the sample solution before making critical measurements to eliminate meniscus effects.
Why: Pre-wetting ensures consistent wetting characteristics and improves accuracy of subsequent volume transfers.

Background reading relevant to this product:
What types of pipettes are compatible with the Levo Plus?
The device is designed for use with both glass and plastic pipettes. Consult the product specifications for specific size ranges and compatibility details.
How do I ensure accurate and reproducible liquid transfers?
Maintain consistent technique with gentle, controlled movements. Practice with known volumes to establish proper operation and verify transfer accuracy before critical applications.
What maintenance is required for optimal performance?
Regular cleaning of the pipette attachment area and periodic inspection of control mechanisms. Replace any worn seals or components that affect vacuum integrity.
Can the device handle corrosive or organic solvents?
Chemical compatibility depends on the materials of construction. Consult the product datasheet for chemical resistance specifications before use with aggressive solvents.
How precise are the volume transfers compared to electronic pipettes?
Precision depends on operator technique and pipette quality. Manual operation provides tactile feedback but may have higher variability compared to electronic alternatives.
Is calibration required for the pipette filler?
The device itself does not require calibration, but accuracy depends on the attached pipette. Use calibrated pipettes and verify transfer accuracy through gravimetric methods.
