Chemical Compatibility: Verify that the pipette pump materials are compatible with the reagents being used; the pump is designed for use with a wide range of laboratory chemicals.
Filter Integrity: Always check that the hydrophobic filter is in place and dry before use to prevent over-aspiration and contamination .
Proper Pipette Fit: Ensure the serological pipette is securely inserted into the silicone adapter to prevent leakage or inaccurate volume aspiration.
Aspiration Technique: Turn the thumb wheel slowly and smoothly to prevent foaming, splashing, or aspiration of air bubbles that can affect volume accuracy.
Pipette Disposal: When discarding a used pipette, follow your facility's guidelines for the disposal of laboratory equipment contaminated with biohazards or chemicals.
Training: Only trained laboratory personnel should operate the Levo E Pipette Pump for clinical diagnostic applications.

2. FIRST AID MEASURES

Sample Splash: If a biological or chemical sample splashes onto the skin, wash immediately with soap and water. If a splash enters the eyes, flush with copious amounts of water for at least 15 minutes and seek medical attention.
Chemical Exposure: If a large volume of a hazardous chemical is aspirated, refer to the specific chemical's Safety Data Sheet (SDS) for detailed first aid instructions.
Mechanical Injury: If the pipette tip punctures the skin (sharps injury), wash the wound thoroughly and follow your facility's exposure management protocol for bloodborne pathogens.

3. FIRE FIGHTING MEASURES

Flammability: The plastic components of the pipette pump are combustible. The primary fire risk comes from the flammable reagents being used in the laboratory.
Extinguishing Media: Use a multi-purpose ABC dry chemical fire extinguisher, CO₂, or alcohol-resistant foam for fires involving electrical equipment or flammable liquids.
Fire Response: If a small fire occurs, follow the laboratory's fire safety protocols and evacuate the area if necessary.
