• How many different volume settings does the YG1778 provide?
  The YG1778 offers 35 different partial volume settings, which can be adjusted depending on the tip size and stroke setting number. This flexibility ensures that the pipette is suitable for a wide range of liquid handling tasks.

• What is the accuracy and repeatability of the YG1778 pipette?
  The YG1778 pipette offers an accuracy of ±0.9% for smaller volumes and up to ±0.4% for larger volumes. Its repeatability ranges from ≤1.40 – 0.60% to ≤0.40 – 0.15%, ensuring reliable results for repeated measurements.

Advantages and Disadvantages

Advantages:

• High precision: With excellent accuracy and repeatability across multiple volume settings, the YG1778 is ideal for high-precision applications.

• Contamination-free operation: The direct displacement principle ensures that no aerosols are formed during dispensing, making it safer and cleaner for lab environments.

• Versatile volume range: The YG1778 offers a broad range of volume settings, from 0.5 μl to 5,000 μl, catering to various tasks from small sample handling to larger liquid volumes.

Disadvantages:

• Manual operation: Although highly precise, the YG1778 still requires manual operation, which may not be as fast as fully automated systems in high-throughput labs.

• Requires regular calibration: For consistent performance, regular calibration and maintenance are necessary, particularly for labs that rely on high-volume dispensing.

• Limited for very large volumes: While it can handle up to 5,000 μl, for extremely large liquid volumes, a more industrial-grade dispensing system may be needed.

Product Use in the Field
