Core Advantages

This multi-manifold parallel freeze dryer enables the simultaneous processing of multiple samples, eliminating the tedium of handling samples one by one. Equipped with four 200mm material trays spaced 70mm apart, it accommodates 849 vials (Φ12mm), 470 vials (Φ16mm), or 252 vials (Φ22mm), significantly saving experimental time.
It also supports freeze-drying in various containers—including vials of different specifications, eggplant-shaped flasks (100ml/150ml/250ml/500ml), ampoules, and glass flasks—thereby meeting diverse experimental requirements and suiting a wide range of laboratory settings.

Frequently Asked Questions

Q: How many vials can this parallel freeze-dryer accommodate at once?
A: Each batch can hold 849 (Φ12mm), 470 (Φ16mm), or 252 (Φ22mm) vials, fully meeting the needs of high-frequency experiments.
Q: Does it support the use of eggplant-shaped flasks?
A: Yes, this manifold freeze-dryer can simultaneously accommodate two flasks each of the 100ml, 150ml, 250ml, and 500ml sizes.
Q: Do I need a separate pre-freezing freezer?
A: No. The cold trap features a built-in pre-freezing function, integrating loading, pre-freezing, and drying into a single unit.
Q: Can freeze-drying data be exported?
A: Yes. This manifold laboratory freeze-dryer automatically records all parameters, and you can export the data via a USB port for archiving.
Q: Is maintenance easy?
A: Very easy. The unit includes a maintenance reminder function that alerts you when servicing is required; the manifold ports are also detachable for easy cleaning.
