About this product
Product information from the supplier.
Applications
Suitable for pilot-scale experiments in biology, medicine, chemical engineering, food science, and other fields. It forms a complete system with vacuum pumps, circulating coolers, and other cooling equipment.
Technical Features
LCD display with digital display of temperature and rotation speed, one-button shuttle setting.
Equipped with a liquid level protection device to prevent dry-burning accidents.
High-efficiency double reflux condenser with a large condensing area and high recovery rate.
The 3.3 borosilicate glass three-way bottle acts as a buffer, preventing material in the rotating flask from entering the condenser due to boiling, ensuring normal distillation.
Utilizes a “PTFE + fluororubber double sealing ring” design to ensure airtightness.
The collection bottle’s interface design is reasonable, allowing for the discharge of collected liquid without affecting the continuous distillation process.
The bath uses electric lifting for easy operation; some models have an external heat-insulating protective cover to prevent burns.
PTFE material discharge valve, corrosion-resistant and pollution-free.
Quick-install flange for easy glass assembly and disassembly.
Casters with brakes facilitate easy movement and installation.
Explosion-proof motors, heaters, and control boxes have the explosion-proof marking Ex db ⅡB T4 Gb.

FAQ
Q: What is the temperature range of the rotary evaporator
A: The temperature range of the rotary evaporator is RT-100C.- Q: What is the maximum pressure that the glass condenser’s coil is rated to? What is the maximum pressure that the condenser itself is rated to?
A: The glass condenser’s coil is rated to 14 psi and the condenser itself is only rated for atmospheric pressure and a vacuum of 3 torr.
- Q: What is the dual receiving flask kit used for on the 20 and 50L rotary evaporators?
A: The dual receiving flask kit is used to remove reclaimed solvent from the evaporator without interrupting its operation. - Q: What heating medium can be used in the water bath?
A: Only distilled water can be used as a heating medium in the water bath of a rotary evaporator. - Q: Can the vacuum level be set on the rotary evaporator?
A: The vacuum level can be set only when a vacuum controller is purchased with the rotary evaporator. Please speak to sales or check the rotary evaporator’s customization section on the website for recommendations.
- Q: What accessories come with the purchase of a rotary evaporator?
A: The accessories that come with each model will be different depending on the unit purchased. An accessories list can be found on the unit’s website listing and can be found in the standard package tab. - Q: What is the evaporation speed of my rotary evaporator?
A: The evaporation speed of the rotary evaporator will depend on what is being evaporated, and the parameters chosen. Please refer to the table for the estimated evaporation rate for ethanol and water.
