Description

The YG1772 series multi-channel pipettes redefine laboratory efficiency with their legendary accuracy and ergonomic design, available in three volume ranges (2-20μl, 5-50μl, and 20-200μl). These air-displacement pipettes feature a magnifying shape for easy volume verification and a color-coded system for quick identification. With ±1.0-6.0% accuracy and ≤0.40-2.50% repeatability, they deliver reliable performance for critical liquid handling tasks. The low operating force and perfect ergonomic positioning reduce user fatigue, while 121°C sterilization capability ensures compatibility with stringent lab protocols.

Frequently Asked Questions

• What makes these pipettes different from standard models?
  They combine chemical-resistant materials with a volume lock system and require only a few turns to adjust volumes precisely.
• Can they handle viscous liquids?
  While optimized for aqueous solutions, the air-displacement mechanism works best with low-viscosity samples.
• Are replacement parts available?
  Yes, all consumable components are available through Kalstein’s certified parts program.

Advantages and Disadvantages

Advantages:

• Unmatched comfort: Ergonomic design reduces hand strain during repetitive use
• Visual clarity: Magnifying shape and color-coding improve workflow efficiency
• Durability: Chemical-resistant materials withstand harsh lab environments

Considerations:

• Not ideal for highly viscous or volatile liquids
• Manual adjustment required for volume changes
• Regular calibration needed to maintain specified accuracy

Field Applications

These pipettes excel in:

• High-throughput screening: Perfect for 96/384-well plate work
• PCR setup: Precise small-volume transfers (2-20μl model)
• Cell culture: Reliable medium dispensing (20-200μl model)

Usage Recommendations

• Calibrate monthly for critical applications
• Store vertically in pipette stands when not in use
• Use manufacturer-approved tips for optimal performance
