Product description

Electronic microinjector for precise injection volumes >100 pL using external pressure, for adherent & suspension cells.

The Eppendorf FemtoJet 4x is an electronic microinjector designed for precise and reproducible injection of small to intermediate sample volumes, especially volumes greater than 100 pL. It requires an external pressure supply (not included) to deliver continuous, controlled injection pressures.

Key features:

  • Compatible with Eppendorf micromanipulators TransferMan 4r and InjectMan 4, enabling semi-automatic microinjection
  • Injection volume range: femtoliters to microliters, optimized for volumes >100 pL
  • Programmable injection settings for high reproducibility
  • User-friendly operation with a small footprint (21.3 × 20.7 × 25 cm)
  • Foot control included; optional hand control available for *Inject and Clean* function activation
  • Pressure settings: injection and compensation pressure programmable from 5 to 6,000 hPa (increments of 1 hPa)
  • Maximum clean function pressure: 6,000 hPa (87 psi)
  • Weight (without accessories): 5 kg

The device emphasizes reliability under demanding research conditions, interfacing seamlessly with both Eppendorf and third-party micromanipulators. The FemtoJet 4x is suited for aqueous injections into both adherent and suspension cells, delivering precise pressure control needed for longer injection series at elevated pressures.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
