History

Kenneth Rainin founded Rainin Instrument Company in 1963 as a distributor of laboratory instruments and supplies. [1] [2]

Rainin began distributing adjustable volume pipettes in 1972 and manufacturing its own in 1980. [3] [4]

In 1999, Rainin launched the LiteTouch System (LTS) to improve pipetting ergonomics by reducing tip loading and ejection forces. [4] LTS pipettes have been recognized for their ergonomic benefits. [5] [6]

METTLER TOLEDO acquired Rainin for $292.2 million in 2001. [7] [8]

As a response to pipette tip shortages during the COVID-19 pandemic, [9] [10] Rainin was awarded a $35.8 million contract from the US Department of Defense to expand domestic production capacity for pipette tips. [11] Rainin subsequently opened a new manufacturing facility in Vacaville, CA in 2022 and installed an in-house electron-beam sterilizer in 2023. [12] [13]
