Microliter

Microliter is a unit of volume in the metric system, equal to one millionth (1/1,000,000) of a liter. It is often used in laboratory measurements and procedures, particularly in the fields of biology, chemistry, and medicine.

Definition

The microliter (symbol: μL) is a non-SI unit accepted for use with the International System of Units (SI). It is equivalent to 1 cubic millimeter (mm³), 0.001 milliliters (mL), or 1/1,000,000 of a liter.

Usage

Microliters are commonly used in laboratory procedures such as DNA sequencing, PCR, and ELISA, where small volumes of reagents or samples are required. They are also used in medical tests and procedures, such as blood tests, where only a small sample of blood is needed.

Measurement

Microliters are typically measured using a micropipette, a laboratory tool that can accurately dispense volumes in the microliter range. Other devices, such as syringes and microcentrifuge tubes, can also be used to measure and handle microliter volumes.
