Pipette Filler (Levo ME)

Pipette Filler (Levo ME)

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Motorized Aspiration for Efficient Liquid Transfer

• Primary Use: Provides a motorized, handheld serological pipette controller designed for fast, efficient aspiration and dispensing of liquids in clinical and research laboratories, compatible with glass or plastic serological pipettes (0.1–100 mL).

• How it helps: For the clinical laboratory scientist, the Levo ME’s powerful motor reduces the time and physical effort required for large-volume liquid transfer tasks. It can aspirate 25 mL of liquid in under 7 seconds, significantly streamlining workflows in diagnostic settings. The motorized aspiration provides consistent suction, which is critical for preventing the introduction of air bubbles that might compromise the accuracy of volumetric measurements. For the patient, this efficiency contributes to faster, more consistent sample processing, supporting timely diagnostic reporting.

2. Adjustable Aspiration and Dispensing Speeds for Versatile Liquid Handling

• Primary Use: Features independently controlled upper and lower buttons for aspiration and dispensing, allowing the user to adjust speeds steplessly according to the task and liquid viscosity.

• How it helps: For the laboratory technician, the ability to fine-tune speed with the fingertips can prevent splashing or foaming, which is crucial for handling sensitive protein solutions or cell cultures. The separate controls for aspiration and dispensing provide a high level of tactile precision. For the patient, this reduces the risk of sample degradation due to mechanical stress, ensuring that the specimen tested accurately represents their biological condition.

3. Long Battery Life and Low Weight for Extended Use

• Primary Use: Powered by a high-capacity lithium-ion battery that provides more than 8 hours of intermittent use on a 2–3 hour charge (and can be used while charging), while weighing approximately 200 grams (approx. 0.44 lbs).

• How it helps: For the laboratory manager, the long battery life supports full daily shifts without recharging, and the option to use it while charging eliminates downtime. The lightweight design minimizes hand fatigue, reducing the risk of repetitive strain injury (RSI) during high-throughput tasks. For the patient, a well-rested and comfortable technician is better able to maintain consistent technique and focus, contributing to the overall reliability of diagnostic assays.

4. Replaceable Filter to Prevent Aerosol Contamination

• Primary Use: Equipped with a replaceable 0.45 µm hydrophobic filter that protects the internal mechanism from liquid overflow and prevents the escape of biohazardous aerosols.

• How it helps: For the biosafety officer and laboratory personnel, this filter is a critical safety feature when handling infectious samples or volatile reagents. It serves as a barrier, safeguarding both the equipment and the user from potential contamination. For the patient, this filter helps prevent cross-contamination between samples, supporting the generation of accurate and reliable test results.

5. Gravity or Motorized Dispensing with Blow-Out Function

• Primary Use: Offers a choice between motor-assisted dispensing for controlled, step-by-step release or gravity-based dispensing for rapid output, with a dedicated “blow-out” function to expel the final drop from the pipette tip.

• How it helps: For the research scientist, the motor control allows for precise, drop-by-drop dispensing, which is essential for layering reagents or filling microplates. The gravity dispensing mode is ideal for rapid, large-volume transfers. The blow-out function ensures complete sample delivery, which is critical for accurate quantitative analysis. For the patient, this versatility ensures that the right tool is available for every laboratory procedure, supporting the overall accuracy of diagnostic and research assays.

SECONDARY & SUPPORTIVE USES

2. Clinical Chemistry and Sample Preparation: Used to aliquot patient sera, plasma, or urine samples for various diagnostic panels and to prepare reagents for automated analyzers.

3. Microbiology and Bacteriology: Used to transfer liquid media, broths, and bacterial suspensions to tubes or plates for culture and antimicrobial susceptibility testing (AST).

4. Pharmaceutical Quality Control (QC): Used to transfer test solutions, dissolution media, and QC samples during the analysis of drug products, ensuring accurate dosing and purity.

5. Analytical Chemistry Laboratories: Used for the precise transfer of solvents, standards, and samples for techniques such as HPLC, GC, and ICP-MS.

6. Blood Bank and Transfusion Medicine: Used to transfer reagents and patient samples for blood typing, cross-matching, and antibody screening.

7. Veterinary Diagnostic Laboratories: Assists with the transfer of samples and reagents for diagnostic testing of animal diseases, supporting animal health and public health surveillance.

8. Food and Beverage Testing: Used to transfer food extracts, buffers, and reagents for quality control and safety testing, including tests for pathogens, allergens, and nutritional content.

9. Educational and Research Institutions: A valuable teaching tool for students to learn accurate liquid handling techniques and a reliable workhorse for routine laboratory tasks.

10. Vaccine Development and Production: Used in the preparation of culture media, antigens, and formulations during vaccine research and manufacturing.

11. Environmental Testing Laboratories: Used to transfer water, soil, and effluent samples for chemical and microbiological analysis, helping to monitor environmental safety.
