Yamato DC401B Freeze Dryer with 8-Port Manifold A Overview
The Yamato DC401 freeze dryer with Manifold A (8-port) and five 120 mL dry flasks is a benchtop lyophilizer with a refrigerated cold trap reaching −45°C and roughly 4 L internal capacity. LabSupplies.com, an authorized dealer, supplies this Yamato Scientific unit complete with straight-glass-joint flasks and caps for direct, sample-ready drying.
A cylindrical stainless steel trap (Dia. 153 × H235 mm) anchors the system, paired with a Pirani vacuum gauge for pressure monitoring. The Hot Gas Bypass System refreezes and removes ice without manual scraping. Automatic safety vacuum venting blocks oil backflow during power-off or power failure, keeping the dried product contaminant-free.
Air cooling rated at 400 W drives the R404A refrigeration circuit (300 g ±5 g). Power runs on AC115V 12 A or AC220V 7 A (50/60 Hz). The cabinet measures 300 × 450 × 920 mm, weighs about 60 kg, rolls on casters, and is made in Japan.
Key Features
- −45°C cold trap: stainless steel cylindrical trap reaches minimum temperature in about 50 minutes from 20°C.
- 8-port Manifold A: drying chamber W304 × D60 × H263 mm with 80 mm port pitch, supplied with five 120 mL dry flasks (straight glass joint and cap).
- Hot Gas Bypass defrost: ice is refrozen and removed smoothly, eliminating manual scraping between runs.
- Contaminant-free venting: automatic safety vacuum venting prevents oil backflow on power-off or power failure.
- Pirani vacuum gauge: integrated pressure readout with a Dia. 17 mm exhaust port for vacuum pump connection.
- Mobile benchtop build: caster-mounted cabinet, ~60 kg, with layered safety devices including an electric leakage breaker and back-flow prevention valve.
How to Choose the Right Freeze Dryer
Selecting a benchtop lyophilizer means matching trap temperature, capacity, and collection format to your sample chemistry and throughput. Use these axes to scope the right unit .
- Trap temperature: a −45°C cold trap suits aqueous and water-based samples; lower-eutectic solvents may need colder traps.
- Capacity: weigh dehumidifying capacity (0.6 L) and internal volume (~4 L) against your batch sizes and run frequency.
- Collection format: manifold drying with glass flasks fits multiple small batches; confirm port count and flask volume match your sample mix.
- Voltage: verify your site supports AC115V 12 A or AC220V 7 A (50/60 Hz) before specifying.
- Footprint and mobility: check bench clearance for the 300 × 450 × 920 mm cabinet; casters allow relocation.
- Safety and uptime: features like Hot Gas Bypass defrost and automatic vacuum venting reduce manual handling and protect samples.
