DIY Picospritzer

I was in Tokyo recently and stopped by my friend Taro Ishikawa’s lab (of TaroTools fame). He and Misa are doing very well. They have exciting work underway and are expanding their lab. Taro’s a resourceful, clever guy and while I was there I saw some more of his handiwork. Instead of buying a Picospritzer (which costs $1500-$3000, the NPI PDES system is less expensive, but still in the 4 digits), Taro hooked a regulator (above) directly to an electric valve (below) and called it a day. The valve is actuated by a TTL pulse, and the regulator sets the pressure. Simple, elegant, saves space, and saves money.
