Eppendorf Pipette Tips Combitips Advanced 1 ml Pack of 100 Tips

Eppendorf 0030089545 Combitips advanced – 1 ml (Eppendorf Quality)

The Eppendorf 0030089545 is a high-precision 1 ml positive-displacement tip designed for the Eppendorf Repeater (Multipette) series. Unlike standard pipetting systems, the Combitips advanced utilizes an integrated piston to displace liquid directly, eliminating the air cushion between the sample and the tool. This design ensures 100% accuracy and reproducibility when dispensing viscous, high-density, or volatile fluids. Optimized for serial dispensing, these tips allow for rapid, repetitive liquid delivery without the need for constant refilling, making them a staple for high-throughput reagent distribution and diagnostic workflows.

Technical Performance and Design

• Positive Displacement Principle: The integrated piston makes direct contact with the liquid, ensuring that reagents with high vapor pressure (like alcohols) or high viscosity (like glycerol) are dispensed without the inaccuracies caused by air expansion or compression.

• Automatic Tip Recognition: Features a built-in sensor coding that allows the Eppendorf Repeater M4, Plus, and Pro models to automatically detect the tip volume and display it on the digital screen, eliminating manual calculation errors.

• Ergonomic Design: The elongated tip geometry allows for easy access to the bottom of most common laboratory tubes and narrow-neck vessels, ensuring maximum sample recovery.

• Hermetically Sealed Piston: The tight-fitting piston wipes the inner walls of the tip clean during dispensing, ensuring nearly 100% liquid delivery and preventing the formation of hazardous aerosols.

Key Benefits & Applications

• High-Throughput Reagent Filling: Ideal for serial dispensing into microplates or cryovials, providing up to 50 dispensing steps with a single filling.

• Volatile & Viscous Fluid Handling: Essential for dispensing detergents, oils, and solvents like Acetone or Ethanol, which typically "drip" from standard air-displacement pipettes.

• Contamination Protection: The integrated piston acts as a physical barrier, preventing radioactive or toxic samples from entering the internal mechanism of the pipette.

• Color-Coded Identification: The 1 ml tip features a specific color code (Yellow) on the packaging and sensor for quick visual identification in a busy lab environment.
