Pipette tips rack

Pipette tips rack: an essential lab item that organizes and protects tips for accurate pipetting.

About this subject

A pipette tips rack is a crucial tool in molecular biology, chemistry, and diagnostic labs. It keeps pipette tips organized, sterile, and easily accessible, preventing cross-contamination. Racks come in various capacities, typically 96 tips (matching 96-well plates) or 384 tips, and shapes: rectangular, circular, or tower styles. Most are made of polypropylene, a chemical-resistant and autoclavable plastic. Some racks feature lids or alignment adapters for multichannel pipettes, speeding up high-throughput workflows. Choosing the right rack depends on tip volume (0.1 µL to 10 mL) and pipette type (single or multichannel).

Frequently Asked Questions

Why does a pipette tip rack need to be autoclavable?

Autoclaving sterilizes the rack and tips before use, critical for aseptic techniques like cell culture or PCR.

Can I reuse a disposable pipette tip rack?

Polypropylene racks can be reused after washing and autoclaving, but tips are typically single-use. Check material resistance to repeated cycles.

What is the difference between a 96-tip and a 384-tip rack?

A 96-tip rack is standard for 8- or 12-channel pipettes. A 384-tip rack is used in high-throughput workflows with electronic or robotic pipettes.
