For applications that require a specific volume to be delivered or aspirated in the nanoliter to milliliter range, Tritech Research offers the motorized MINJ-PD Digital Positive Displacement microINJECTOR™. Unlike most other microINJECTORs, this system does not require attachment to a gas cylinder, pump, or compressed air line.

With the injection volume and speed set in advance, this motor-driven microinjector injects very small volumes of liquid with precision control via a foot switch, leaving both hands free for micromanipulation and focusing the microscope. There is also a Manual Mode that allows the user to inject without knowing the volume in advance. In Manual Mode, the MINJ-PD keeps a tally of the amount injected. The specifications of the MINJ-PD allow precise control of injection and aspiration.

For stem cell injection, a special built-in Agitation Mode helps to prevent cells from clumping and settling on the wall of the needle.

The MINJ-PD employs the same user-friendly microprocessor interface as the MINJ-D. It digitally synthesizes injecting / aspirating volume and speed, as well as agitating volume and speed, reproducibly. Using a simple "Menu" button, and Plus and Minus buttons, anyone can set the volumes and the speeds in seconds. Here are the key features and specifications of the Positive Displacement Digital microINJECTOR™:
