When your lab needs vacuum for solvent removal, filtration, or degassing, the first decision is whether you need a dedicated vacuum pump or a complete rotary evaporation station. The HFS 2 Stage 12CFM 1HP Laboratory Vacuum Pump and the Taishi 2L Rotary Evaporator Lab Connect to Vacuum Pump Chiller Manual Lifting Rotovap sit at opposite ends of that decision, with a listed price spread from $199.00 to $516.99.
Quick Verdict
- For general vacuum work, the HFS 2 Stage 12CFM 1HP Vacuum Pump is the straightforward choice. It is a portable, used 2-stage pump with 12 CFM free air displacement, 3 x 10^-1 Pa ultimate vacuum, and a 1HP motor.
- For rotary evaporation, the Taishi 2L Rotary Evaporator provides the glassware, manual lifting, and stainless-steel bracket needed to build a rotovap setup. The title says it connects to a vacuum pump and chiller, so it works as the evaporation module in a larger system.

Where Each Product Wins
Choose the HFS pump for: standalone vacuum generation with a portable, used 2-stage design. It is made in the United States, runs on 110-127V~ 60Hz, and is described as tested for power and basic function, though not for field use.
Choose the Taishi rotovap for: rotary evaporation with manual lifting, a stainless-steel bracket, high-temperature-resistant glass, and 1L collecting and evaporation flasks. This new unit is designed to be paired with a vacuum pump and chiller.
Product Notes
HFS 2 Stage 12CFM 1HP Laboratory Vacuum Pump VP 2200
This used, portable pump is built in the United States and features a 2-stage vacuum design with 12 CFM free air displacement and a 1HP motor. Its ultimate vacuum is specified at 3 x 10^-1 Pa, and it operates on 110-127V~ 60Hz power. If you need a dedicated vacuum source for lab applications, this pump gives you a straightforward, moveable unit that was tested for power and basic function, but not in the field of use. The used condition is the main limitation: you are relying on the stated functional test rather than application-level validation. The portable feature supports moving it where you need vacuum.
Taishi 2L Rotary Evaporator Lab Connect to Vacuum Pump Chiller Manual Lifting Rotovap
This new rotary evaporator brings together a 2L capacity, manual lifting, and a stainless-steel bracket, with 1L collecting and evaporation flasks made of high-temperature-resistant glass. The title explicitly says it connects to a vacuum pump and chiller, so it fits into a larger system rather than replacing your pump. The gross weight is listed at 64.37 lbs. For labs that are assembling a rotary evaporation setup, this rotovap provides the glass and lifting mechanism in a single new unit.
Final Choice by Use Case
- If you need a portable vacuum pump for general lab work and want a used 2-stage unit, choose the HFS pump.
- If you are assembling a rotary evaporation setup and need a new rotovap with manual lift and 1L glassware, choose the Taishi unit.
