Eppendorf FemtoJet Programmable Microinjector

Combine with TransferMan or InjectMan to form an ideal system



High–quality microinjection results require precision and reliability. Eppendorf's electronic microinjectors, the FemtoJet® 4i and FemtoJet 4x, are your tools of choice for reproducibly injecting small volumes into adherent cells and suspension cells. In combination with the TransferMan® 4r or InjectMan® 4 they form an ideal system to facilitate and speed up your workflow.



  • Very simple and clearly arranged operation for routine tasks
  • Injection volume ranges from femtolitres to microlitres
  • Inject and Clean functions 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)


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.
