Why order the DC401 from LabSupplies.com
Key Features
- Refrigerated cold trap: stainless steel cylinder reaches -45°C, cooling from 20°C in about 50 minutes.
- Contaminant-free venting: automatic safety vacuum venting prevents oil backflow on power-off or power failure.
- Pirani vacuum gauge: monitors chamber pressure throughout the lyophilization cycle.
- Layered safety devices: electric leakage breaker with overcurrent protection, refrigerator overload relay, back-flow prevention valve, and a safety valve linked to the vacuum-pump service receptacle.
How to Choose the Right Freeze Dryer
- Drying capacity: the 4 L chamber and 0.6 L dehumidifying capacity define how much moisture you can collect per run.
- Voltage and power: verify your circuit supports the chosen 115V or 220V configuration before ordering.
- Footprint and mobility: confirm the 300 × 450 × 920 mm body and ~60 kg weight suit your bench, then use the casters to reposition.
- Configuration needs: this is the main unit; budget separately for drying chamber, manifold, mounting flasks, caps, and glass containers.

Frequently Asked Questions
What is the drying and dehumidifying capacity?
The DC401 provides roughly 4 L of internal drying capacity with a 0.6 L dehumidifying (ice-collection) capacity per run.
What voltage options are available, and what power does it draw?
The DC401 is offered in 115V and 220V configurations. The 115V version operates on AC115V, 12 A at 50/60 Hz, so confirm your circuit before ordering.
What are the external dimensions and weight?
External dimensions are 300 × 450 × 920 mm (W×D×H) with a weight of approximately 60 kg. Built-in casters keep the unit mobile on the bench.
Is the drying chamber and glassware included?
No. The DC401 is sold as the main unit. The drying chamber, manifold, mounting flasks, flask caps, and glass container are sold separately. Vacuum silicone grease and a vacuum hose are included.
What is the difference between DC-401-115V and DC-401-220V?
DC-401-115V is the 115V configuration. DC-401-220V is the 220V configuration. Order the catalog number that matches your facility's electrical supply.
What safety devices does the Yamato DC401 have?
Yamato lists these safety devices for the DC401: electric leakage breaker with overcurrent protection, refrigerator overload relay, back-flow prevention valve, safety valve linked with vacuum-pump service receptacle.
What refrigeration system does the Yamato DC401 use?
