TwinTip adapter for the Nano-Plotter
Chemical reactions at a microscale and hardening of two-component systems are just two applications for the new TwinTip adapter for the Nano-Plotter. In contradiction to other micro mixers the TwinTip adapter allows to aspirate tiny volumes of two different species from a standard micro well plate.
The TwinTip adapter accomodates the native GeSiM piezoelectric pipets as well as solenoid dispense valve pipets. Following setups are possible:
- Two GeSiM piezoelectric pipets with drop volumes between 60 pL and 400 pL
- Two solenoid valve pipets with droplet volume of 50 nL
- One GeSiM pipet, one solenoid valve
The TwinTip adapter toggles the pipets between two positions: OPEN (Aspiration/ wash position) and CLOSE (Dispense position). Simultaneous drop release at the CLOSE position leads to a perfect mix up of both drops on the target surface due to the high kinetic energy of the drops.
