Your Professional Manufacturer of Rotary Evaporator
As a professional cannabis lab equipment manufacturer, HiURTB cannabis rotary evaporators deliver precision solvent recovery and cannabinoid concentration for extractors and R&D labs.
Engineered with explosion-proof technology and vacuum anti-reflux systems, the HiURTB rotary evaporator ensures maximum safety during ethanol/butane extraction of cannabinoids.
Featuring digital control over rotation (0-310rpm) and temperature (-50°C to 180°C), plus industrial-grade condensers for 30% faster distillation, we optimize terpene preservation and THC/CBD yield.
The 2L and 5L models are preferred by cannabis processors for R&D and pilot-scale production. Custom large-scale rotary evaporator (up to 100L or above) available.
HiURTB cannabis rotary evaporator is the essential Solvent Recovery and Concentration Center in your complet workflow below. After initial extraction, it’s the critical step that reclaims expensive solvents and prepares your extract for purification.
* End-to-End Solutions: CO₂ extraction (HiURTB CO₂ cannabis extraction equipment) → Solvent Recovery & Concentration (HiURTB Cannabis Rotary Evaporator)→ Purification (HiURTB Short Path Distillation Kit) → Reaction (HiURTB Glass Reactors).
* Support Equipments: Circulating water vacuum pumps & low-temp coolant circulators ensure optimal performance.
Zero-Risk Extraction for Flammable Solvents
* Explosion-Proof Rotary Evaporator: ASME-certified vacuum seals + reinforced armored glass
* Zero Backflow: Dual valves and pressure release automation prevent butane or ethanol backflow.
* Fail-Safe Operation: Motorized lift removes flasks from the heat source instantly during emergencies.
More Terpenes, Faster Recovery
* Precision Cryo-Control: -50°C to 180°C range (±0.5°C) with dry ice compatibility for heat-sensitive terpenes
* 50% Faster Ethanol Recovery: Dual serpentine condensers of HiURTB rotary evaporators
* Self-Adjusting Rotation: Digital RPM/temp control (0-310rpm) + reversible rotation for even film formation.
Grow from Lab to Factory
* Plug Your Gear: Plug-and-play with chillers/vacuum pumps & CO₂ extractors
* Scale On Demand: 2L (R&D) → 5L (pilot) → Custom 100L or more large scale rotary evaporators
* cGMP Compliance: Full audit trails for extraction protocol documentation
ATEX-certified explosion safety handles ethanol/butane with zero risk
-50°C terpene lock technology achieves >95% heat-sensitive compound retention for premium cannabis extracts. 50% faster solvent recovery.
GMP-ready 20L/hour ethanol recycling processing (200L/day) with auto batch documentation.
Cluster-compatible ATEX design supports 100L+ hydrocarbon extraction under full nitrogen purge.
Self-cleaning condensers and dual-chill (-70°C) prevent downtime in continuous 24/7 operation.
Core Principle: Low-Temp Solvent Recovery
1) Pressure Reduction → Lower Boiling Point
Vacuum system depressurizes to 0.08-0.1 mbar
Boiling point drops 60-80% (e.g., ethanol boiling point: 78°C → 28°C)
2) Rotary Thin-Film Evaporation
The evaporating bottle rotates at 50-310 rpm→
Forms 0.1-0.3mm solvent film → the evaporation area increases by 5-8 times
3) Cryo-Condensation Capture
Vapor passes through a -50°C dual serpentine condenser→
Liquefied solvent flows into the collection flask
Cannabis application: Protect terpenes and gently evaporate solvent at 35-40°C, with a recovery rate of >92%.
There is a 6-Step Safe Protocol.
| Step | Operation Critical | Parameters Equipment | Tips |
| 1) Prep & Load | Crude extract materials and solvent are injected into the evaporating bottle. | Solution ≤50% of bottle capacity (≤2.5L in 5L bottle) | Use a wide-mouth evaporating bottle to prevent sticky oil from sticking to the wall. |
| 2) Cool Down | Coolant is passed through the condenser. | Terpene protection: -50°C (dry ice + ethylene glycol) | When operating butane: coolant <-45°C |
| 3) Vacuum Start | Start the vacuum pump | Ethanol extraction: 0.1 mbar Butane extraction: <0.5 mbar | First nitrogen purge for 3 minutes (explosion-proof) |
| 4) Set Conditions | Set bath temperature/speed | Ethanol: 40°C/200rpm Butane: 30°C/150rpm | High viscosity oil: use the reverse function |
| 5) Immerse & Run | Immerse the evaporating bottle in the bath | Electric lift: one-button down Manual lift: clockwise rotation of the wheel | Sudden pressure relief → immediate lift |
| 6) Shutdown | Stop → Release pressure → Take the bottle | Collection volume ≥ 90% of input solvent | Precool the collection bottle to -20°C |
