Yamato CA301 Refrigerated Cold Trap, 4L (−45°C) Overview
The Yamato CA301 Cold Trap is a refrigerated cold trap with a 4 L trap capacity and a minimum temperature of -45°C, sold by LabSupplies.com as an authorized Yamato Scientific dealer. Mechanical cooling removes the need for dry ice or liquid nitrogen during operation.
Power options cover AC115V and 220V, letting labs match site supply. Casters with front-wheel stoppers make the unit mobile across benches and equipment rows. Dual roles as a low-temperature bath or pre-cooling tank extend its use beyond pump protection.
Key Features
- Minimum temperature -45°C: mechanically cooled trap reaches deep cold without dry ice or liquid nitrogen.
- 4 L trap capacity: condenses and holds moisture and harmful vapors ahead of the vacuum pump.
- Dehumidifying capacity to 0.9 kg: rated maximum for water-type liquids during continuous operation.
- CFC-free, air-cooled refrigeration: environmentally conscious refrigerant with an air-cooling condenser system.
- Stainless steel condenser: standard build, with an optional glass trap for corrosive vapors.
- Mobile cart design: mounted on casters with front-wheel stoppers for positioning and lock-down.

Frequently Asked Questions
What is the minimum temperature of the Yamato CA301 cold trap?
The CA301 reaches a minimum trap temperature of -45°C. Mechanical refrigeration drives the cooling, so no dry ice or liquid nitrogen is required to hit that temperature.
What is the trap capacity of the CA301?
The CA301 has a 4 L trap capacity. It carries a dehumidifying capacity of up to 0.9 kg for water-type liquids during operation.
What voltage options are available?
Two voltage configurations are offered: 115V (CA-301-115V) and 220V (CA-301-220V). Select the option that matches your laboratory's available circuit.
What is the condenser made of?
The standard condenser is stainless steel. An optional glass trap is available for applications involving corrosive vapors.
Does the CA301 need dry ice or liquid nitrogen?
No. The CA301 uses a CFC-free, air-cooled mechanical refrigeration system, eliminating the recurring cost and handling of dry ice or liquid nitrogen.
What can the CA301 cold trap be used for?
It protects vacuum pumps on vacuum ovens, rotary evaporators, and freeze dryers by trapping moisture and harmful vapors. The unit also functions as a low-temperature or pre-cooling tank.
What is the difference between CA-301-115V and CA-301-220V?
CA-301-115V is the 115V configuration. CA-301-220V is the 220V configuration. Order the catalog number that matches your facility's electrical supply.
What refrigeration system does the Yamato CA301 use?
The Yamato CA301 uses air cooling and CFC-free refrigerant refrigerant.
