HNZXIB FD-04 4L Freeze Dryer -50°C with Vacuum Pump

4 L laboratory freeze dryer

The HNZXIB FD-04 is a 4-litre vacuum freeze dryer built for laboratory and small-batch production use. A Secop compressor drives the cold trap down to -50 °C while the included rotary vane pump pulls vacuum below 15 Pa. The unit processes 4 to 6 kg of material per cycle across four trays measuring 200 by 425 mm, offering 0.4 m² of total drying area. Operation runs on 110 V 60 Hz power with a rated draw of 1.5 kW.

Suits labs needing visual process monitoring

The transparent plexiglass door lets operators watch sublimation in real time without breaking vacuum, which is valuable for method development and quality checks. An LCD control panel simplifies parameter entry for both experienced technicians and new users. Buyers who require higher throughput, larger chamber volumes, or three-phase power should evaluate other platforms because this model is limited to single-phase 110 V supply and a 4 kg to 6 kg batch range.

Bundled pump and trays enable immediate runs

The package includes a 2XZ-2 rotary vane vacuum pump rated at 2 L/s exhaust speed with a 25 mm KF-25 inlet, plus four stainless trays that fit the chamber directly. Pump noise is specified at 70 dB and oil capacity is 0.65 L, so the system is ready to operate once connected to a suitable 110 V circuit. No additional accessories or software licences are mentioned in the supplied data.
