Eppendorf's electronic microinjectors FemtoJet 4i and FemtoJet 4x with their simple operation menu and a range of functionalities are perfectly suited for injecting small to intermediate volumes. With a built-in compressor, the FemtoJet 4i is the tool of choice for injecting aqueous solutions into adherent cells and suspension cells. If your research demands injecting volumes greater than 100 pL and/or longer series at higher pressures, FemtoJet 4x with its external pressure supply (not included) delivers the precise and continuous pressure required. Featuring the same quality design and compatibility features as the FemtoJet 4i, the FemtoJet 4x is the "heavy duty" device for those more demanding applications. Both the FemtoJet 4i and FemtoJet 4x, form the perfect system with Eppendorf micromanipulators, yet they integrate just as easily with non-Eppendorf micromanipulation systems. The electronic connection between FemtoJet 4i or 4x and TransferMan 4r or InjectMan 4 guarantees simple, rapid and reproducible microinjections into cells, simplifying your daily work and speeding up your workflow. The FemtoJet 4i/ 4x injectors are for research use only.

• Injection volume ranges from femtoliters to microliters
• Inject and Clean function can be triggered right on the device using the included mouse or optional foot control
• Programmable injection guarantees high reproducibility
• Connection to TransferMan 4r, InjectMan 4 or InjectMan NI 2 enables semi-automatic microinjection
• Small footprint
• Can be combined with all conventional micromanipulation systems
• Independent pressure supply via built-in compressor (only FemtoJet 4i)
• Reproducible and serial microinjection into adherent cells when combined with the InjectMan^® 4 or InjectMan^® NI 2 micromanipulator
• Microinjection into small organisms and embryos in the early stages of development (e.g., Drosophila melanogaster, Zebrafish, etc.)
