10L-50L Pharmaceutical & Chemical Concentration Distillation Equipment: Large Rotary Evaporator Overview
Core Abstract (核心摘要) The RE Series Large Rotary Evaporator is a high-efficiency distillation and concentration equipment designed for continuous solvent recovery under controlled vacuum conditions. It is specifically optimized for the pharmaceutical, chemical, biological, and plant extraction industries, proving essential for crystallizing, drying, and separating heat-sensitive materials. Manufactured by CECLE (Wenzhou T&D Packaging Machinery Factory), its core advantages include versatile processing capacities from 10L to 50L and the utilization of premium high-borosilicate glass for unparalleled chemical corrosion resistance. Paired with a large-surface-area condenser and a precisely controlled heating bath, it guarantees rapid evaporation rates and exceptional purity for industrial-scale production.
I. Product Overview & Core Advantages (产品概述与核心优势)
The RE Series Large Rotary Evaporator is engineered for pilot-scale and continuous industrial processing. It operates by rotating a large glass flask under negative pressure, creating a thin film of the solvent for highly efficient, uniform heating. Its core advantages include:
- High-Borosilicate Glass Construction: All glass components (spin bottle, collection bottle, and condenser) are crafted from durable high-borosilicate glass, offering superior thermal shock resistance and inertness to highly corrosive chemicals.
- Optimized Condensation Efficiency: Features a large-area dual-spiral condensing tube (up to 1.5m² on the 50L model) that rapidly converts chemical vapors back into liquid form, achieving impressive water evaporation rates (up to >9L/h).
- Precision Flange Sealing: Utilizes a robust flange sealing mechanism (ø95 to ø125) combined with high-quality PTFE seals to maintain an optimal, stable vacuum state, which is critical for lowering the boiling point of heat-sensitive solvents.
- Reliable Speed & Temperature Control: Equipped with a stable rotary motor offering adjustable host speeds (10-120 r/min or 10-90 r/min depending on model size) and a dedicated 3kw heating bath to ensure consistent evaporation conditions.

III. Packaging & Shipping Information (采购包装与物流须知)
For international buyers and large-scale industrial procurement, we ensure stringent packaging and reliable global transit:
- MOQ & Secure Packaging: The minimum order quantity (MOQ) is 1 set. Given the fragility of large glass components, the main frame, heating bath, and glassware are meticulously packed in custom-fitted protective foam and securely enclosed in a heavy-duty wooden case.
- Delivery Term: Standard equipment is processed and dispatched following order confirmation. Standard spare parts and assembly tools are included in the crate.
- After-Sales Warranty Policy: The mechanical and electrical components come with a one-year warranty. If any non-human damage occurs during proper operation, we provide free replacement parts or technical support (the customer is only responsible for international shipping fees). We offer continuous lifetime technical consultation beyond the warranty period.
IV. Frequently Asked Questions (FAQ)
Q: What types of industries benefit most from using this large rotary evaporator? A: This equipment is highly suitable for the pharmaceutical, chemical, and biological sectors, particularly in processes involving plant extraction (like CBD), solvent recovery, concentration of active pharmaceutical ingredients (APIs), and fine chemical synthesis.
Q: Why is high-borosilicate glass used for the flasks and condenser? A: High-borosilicate glass provides excellent resistance to thermal shock, meaning it can handle rapid temperature changes without cracking. It is also highly inert, preventing it from reacting with corrosive solvents, acids, or alkalis, which ensures the absolute purity of the recovered material.
Q: How does the system achieve such high evaporation rates? A: The high evaporation rate is achieved by combining three factors: a stable vacuum environment that lowers the solvent's boiling point, a rotating flask that spreads the liquid into a thin, continuously heated film, and a massive condensing area (up to 1.5m²) that rapidly cools vapors back into liquid.
