With Prime Tech's knowledge and well established experience in microinjection, and their long-standing expertise in Piezo technology demonstrated in the very popular PMM-150FU, Prime Tech has created the new Piezo PMM4G.

Improvements introduced in the Piezo PMM4G include: a smaller and more efficient drive unit with improved force transmission efficiency to the pipette, 3 programmable modes: Standard, Piezo-ICSI and Expert to optimize handling for specific protocols, and an improved Piezo design that provides a smoother and more efficient impact. The advanced user interface with a touch screen makes it easy to input and displays current injection parameters in a compact design that fits easily around the microscope. In addition, the new controller gives the user the ability to more precisely set the driving force.

Prime Tech is very pleased to introduce the new Piezo PMM4G whose new designs, features and functions allow the user to achieve a level of micromanipulation that is "gentle on the oocyte and the operator." The PMM4G is easy to use for both the beginner and the expert!

Training Unit [MB-D]

The new MB-D drive unit is easily mounted on the manipulator and has increased durability and performance. PMM4G allows for smoother injection due to improvements in the drive unit.

Interface Module [TS-1]

PMM4G's touch screen interface displays the various "mode" choices and settings. The interface module is compact and can easily be placed next to the user. Settings can be selected or an on/off switch can be used to control the entire unit.


The MPAS-CT4G controller includes a power saving feature and has been reduced in size from the previous PMAS-CT150 model. The new controller remains compatible with the PMM-150HJ/FU [OP-15] operation box.
