Hand strain is an all-too-common problem for operators when pipetting. The manual Rainin Pipet-Lite Xls+ and electronic Rainin E4 Xls+ from Rainin Instrument LLC all are ergonomically designed to eliminate hand strain while providing high channel-to-channel consistency. Reduced weight and lower pipetting/tip-ejection forces—combined with improved balance—reduce operator fatigue during 96-well plate work. Cross-contamination is minimized through reduced stiction, which helps eliminate splash-up. Both models are available in volumes up to 300 μL. Rainin Instrument LLC
