LiteTouch System

The Rainin LTS™ system is composed of a thin, perfectly sealed joint and a positive stop moulded inside each tip. These two mechanisms allow the cone to be loaded onto the pipette and ejected more easily, thus reducing the risk of injuries.

Constant pipetting can lead to injuries. The Rainin LTS LiteTouch System protects pipette users by making tips practically effortless to load and reduces the force require to eject the tips by up to 85%.
