Rainin operates as an international provider of laboratory pipettes, liquid handling devices, consumables, and related services tailored for life sciences, biotechnology, and pharmaceutical research sectors. Headquartered in Oakland, California, Rainin functions as a division of METTLER TOLEDO, a global leader in precision instruments and service solutions.

History

The Rainin Instrument Company was established by Kenneth Rainin in 1963, initially serving as a distributor of laboratory equipment and supplies.

In 1972, the company began offering adjustable volume pipettes through distribution channels and progressed to manufacturing its own models by 1980.

The introduction of the LiteTouch System (LTS) in 1999 marked a significant advancement aimed at improving pipetting ergonomics by minimizing the forces required for tip loading and ejection. This innovation has been widely acknowledged for its ergonomic advantages.

In 2001, METTLER TOLEDO purchased Rainin for $292.2 million.

During the COVID-19 pandemic when pipette tip supplies were constrained, Rainin obtained a $35.8 million contract from the US Department of Defense to boost domestic manufacturing capacity. Subsequently, the company inaugurated a new production facility in Vacaville, CA in 2022 and incorporated an on-site electron-beam sterilization system in 2023.
