Available from Hamilton Company (cat # 83700). Allows to dispense accurately as little as 200 nL of protein laden LCP (when coupled to a 10 μL syringe) when manually setting up crystallization trials (Cherezov & Caffrey, 2003). The dispenser could be easily modified to reduce the dispensing volume to ~70 nL (Cherezov & Caffrey, 2005).
