Products Description
Our 20L rotary evaporator (rotovap) delivers efficient thin‑film evaporation under precise vacuum and temperature control. It enables gentle concentration, crystallization, solvent recovery, and purification-perfect for heat‑sensitive materials in pharmaceuticals, biotechnology, fine chemicals, essential oil extraction, and CBD refinement. This mid‑scale industrial rotovap is widely used in university labs, research institutes, pilot plants, and small‑batch production lines. It provides stable, safe, and high‑purity separation for hydrothermal synthesis, distillation, and sample preparation workflows.
Core Advantages of 20 Liter Rotovap:
1. High Solvent Recovery
Dual‑condenser system ensures >95% recovery rate, optimized for high & low boiling point solvents.
2. Premium & Durable Materials
GG‑17 borosilicate glass with excellent thermal shock resistance; wetted parts in SS304 & PTFE for corrosion resistance.
3. Automatic & Safe Operation
Electric anti‑collision lift, auto pressure release, and sealed feeding for safe, 24/7 stable running.
4. Precision Control System
Digital speed regulation, accurate temperature control, and analog vacuum gauge for stable performance.
5. Customizable & Certified
Dual condensation, dual collection system, multi‑voltage, OEM/ODM available; CE,ETL, ISO Certificate for global markets.
