FemtoJet® micro-injection system ~ overview

For injecting small to intermediate volumes (up to 100 pl), the original FemtoJet is perfectly suited, featuring a wide range of functionality, simple operation and built-in compressor to independently deliver the required pressure.

It is ideal for injecting aqueous solutions into adherent cells (and makes the ideal partner with our InjectMan NI 2 and 5179, as well as Model 5171) and suspension cells (with TransferMan NK 2). The FemtoJet forms the perfect system with Eppendorf micromanipulators, and it integrates just as easily with non-Eppendorf microinjection systems.

Applications: FemtoJet

• Semiautomatic injection into adherent cells with InjectMan NI 2 (and older models 5171 and InjectMan 5179)
• Suspension cell injection with TransferMan NK 2
• Pronuclear injections into mouse embryos
• Serial injection volumes from femtoliter up to 100 pl

• Inject and Clean functions triggered via control button on instrument, supplied mouse or optional foot control
• Electronic linkage to InjectMan NI 2
• Easily combined with all common micromanipulation systems

FemtoJet in comparison with our new FemtoJet express

The FemtoJet and our new FemtoJet express microinjectors are non identical twins sharing many features, which makes them both an excellent choice for any kind of microinjection of aqueous solutions into adherent cells, suspension cells or small organisms.

The important difference is that the new FemtoJet express uses pressure from an external supply while the FemtoJet has a build in compressor to work as a stand alone unit. Both share the identical broad range in settings for injection time and pressure, but the external pressure supply makes the FemtoJet express the preferred choice if injecting greater volumes ( >100 picoliters) and/or longer series at higher pressures are required - as increasingly seen in functional genomics and developmental biology applications.

Both the FemtoJet and FemtoJet express feature the identical range of injection times and pressures to address a wide range of applications. If higher volumes are required more often in your experiments, the FemtoJet express is our recommendation, while the FemtoJet should be your choice if you preferrently use smaller volumes.
