Science King 20L Dual Condenser Rotary Evaporator (R1020 Dual)
Reference: SK-R1020-Dual
Manufacturer: Science King
- 20L boiling flask, two collection flasks
- Dual main and secondary condensers
- 6 kW heated bath with electric lift
- PID digital temperature control
A 20L rotary evaporator with dual condensers: a main and a secondary condenser give about 1.5× the condensing area and more collection capacity, so it recovers solvent faster than a single-condenser unit of the same size.


- Dual main and secondary condensers: about 1.5× the condensing area and more collection capacity
- More heating power with a dome cover, faster evaporation and less vapour to the room
- PID temperature controller with digital display
- Electric water bath lifting, 3.3 borosilicate glass
- Manual vacuum valve: no loss of vacuum while discharging
