The d2 is small! Only slightly wider than an SBS plate.

Small enough to fit onto any bench, under an extraction hood or into an existing automation system.

Gyger hard closing digital valve

At the heart of the d2 dispenser are high quality hard-closure valves from Fritz Gyger AG of Switzerland. swiss flag

By utilizing ruby and sapphire as the valve closing materials, very high chemical resistance and compatability can be achieved.
  1. Closing spring
  2. Valve ball - using ruby
  3. Valve seat and nozzle - using sapphire

D2 SBS microplate dispenser on a Tecan liquid handler deck.

A perfect partner to your liquid handler.

The d2 will fit on deck of most liquid handlers to complement tip based liquid handling.

  1. Less usage of disposable tips, less plastic waste and lower costs
  2. Lower dead volumes vs use of fixed tips
  3. Bulk fill plates with multiple different fluid types, without the need for multi-way valves and large dead volumes
  4. High accuracy dispensing with very low CV values
