- Durability: Sapphire is second only to diamond in terms of hardness. Because of their extreme toughness, sapphire pipette tips last longer and require less replacement than other materials.
- Chemical resistance: Sapphire is chemically inert and non-reactive, making it suitable for use with a wide range of chemicals and reagents. This property ensures that the tips will not contaminate the samples or react with the substances being transferred.
- Autoclavable: Sapphire pipette tips can withstand high temperatures and autoclaving, a common sterilization method used in laboratories. This allows for reliable and convenient sterilization, ensuring the tips remain free from contamination.
- Repellency: Sapphire has a low surface energy, which gives it hydrophobic properties. This means that liquids, particularly aqueous solutions, tend to bead up and roll off the surface of sapphire pipette tips. This property helps to prevent sample retention and ensures accurate and precise liquid handling.
- Precision and consistency: The manufacturing process of sapphire pipette tips allows for tight tolerances, resulting in tips with consistent dimensions and excellent sealing properties. This ensures reliable and reproducible liquid transfer, especially when working with small volumes.
