Eppendorf InjectMan® 4

Eppendorf InjectMan® 4

Microinjection of cells is a highly versatile method to answer a wide range of biological questions. With its superior stability and comprehensive advanced functions, the Eppendorf InjectMan® 4 is the ideal tool for microinjection into adherent cells, smaller organisms and embryos in the early stages of development.

Product Information

The InjectMan 4 is ideal for microinjection into adherent cells, smaller organisms and embryos in the early stages of development. In combination with the FemtoJet 4i or 4x, it enables fast semi-automatic injection. Furthermore, the InjectMan 4 is the ideal micromanipulator for all complex applications that require a dynamic movement mode and direct control of the injection process via the joystick button. The axial injection movement (X/Z direction) helps to minimize mechanical stress to the cells upon injection. The high penetration speed makes injection into rigid structures easier than ever. The new user interface with four pre-defined application masks facilitates the individual workflow process (e.g., for adherent cell injection, serial microinjection into fish larvae, etc.). The freely programmable "My app" mask can be optimized for individual needs. Due to its exceptional precision and position stability, the InjectMan 4 is highly suited for applications such as patch clamp. The motor modules can be uncoupled electronically to prevent accidental movement of the micropipette. The InjectMan 4 is for research use only.
