Pipette tips rack

Pipette tips rack, an essential lab item for organizing and preventing contamination during liquid handling procedures.

About this subject

The pipette tips rack is a fundamental accessory in biology, chemistry, and diagnostics laboratories. Typically made of durable plastic like polypropylene, it keeps tips sterile and organized, ready for use. Models range from simple 96-well racks to adjustable versions for different volumes (10 µL, 200 µL, 1000 µL). The tip arrangement follows microplate patterns, facilitating work with multichannel pipettes. Proper use of the rack reduces risks of cross-contamination and tip damage, which can affect experimental accuracy. In high-throughput labs, racks are often reusable after autoclaving or disposable for biosafety. An interesting point: rack design also influences lab worker ergonomics, minimizing repetitive movements during pipetting.

Frequently Asked Questions

What is the function of a pipette tips rack?

To organize and protect pipette tips from contamination, keeping them sterile and properly positioned for use with manual or electronic pipettes.

Can pipette tip racks be reused?

Yes, if they are autoclavable. Many polypropylene racks withstand high temperatures, but disposable racks are common in high-risk environments.

How to choose the right pipette tip rack?

Consider the tip volume, format (96-well, 384-well), and compatibility with multichannel pipettes. Adjustable racks offer greater versatility.
