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 100pL 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 Calibre Scientific micromanipulators, yet they integrate just as easily with other 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.

Applications:

• 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.)
• Microinjection into suspension cells when combined with the TransferMan® 4r micromanipulator (e.g., pronuclear injection of fertilised mouse oocytes)

Features:

• Very simple and clearly arranged operation for routine tasks
• Injection volume ranges from femtoliters to microliters
• Inject and Clean function can be triggered right on the device or by 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)
• External pressure supply guarantees the continuous availability of higher injection pressures – even with large volumes and very short intervals (only FemtoJet® 4x)
• Programmable microinjector with integrated pressure supply
