The TOPTION series rotary evaporator is an indispensable core instrument in modern laboratories, specifically designed for the efficient and gentle removal of solvents from liquid samples. It operates by heating the sample and continuously rotating the sample flask under vacuum conditions, thereby increasing the sample's evaporation surface area and accelerating solvent evaporation. The evaporated solvent vapor is then condensed by an efficient condensation system and collected, achieving separation, purification, concentration of the sample, or solvent recovery. With their excellent performance, stable operation, and user-friendly design, our rotary evaporators are widely used in research and production across various fields such as chemistry, pharmaceuticals, bioengineering, food science, and environmental protection.

Intelligent Control System:

Equipped with a high-precision digital display temperature controller for precise control of the heating bath temperature (water bath/oil bath optional), offering a wide temperature range and high stability.
Digital display and control of rotation speed, ensuring smooth and adjustable rotation to meet the needs of materials with different viscosities.
An optional vacuum controller for precise setting and stable control of vacuum levels, optimizing evaporation efficiency.
Integrated control panel for intuitive and convenient operation, with all parameters visible.

Efficient Evaporation & Condensation:

Main and auxiliary condenser designs (coil/spherical optional) provide a large condensation surface area, coupled with efficient cooling medium circulation, ensuring rapid solvent condensation and high recovery rates.
The evaporating flask is made of high-quality borosilicate glass (GG-17), resistant to high temperatures and corrosion, with good transparency for easy observation.
Unique sealing system design, utilizing PTFE and special rubber composite seals, offers strong corrosion resistance and maintains a high vacuum level in the system.

User-Friendly & Safety Design:

Electric or manual lifting of the heating bath, ensuring smooth elevation, allowing operators to quickly immerse or remove the evaporating flask from the heating medium.
Optional explosion-proof motor and circuit design to meet special safety requirements.
The heating bath is equipped with anti-dry burn protection and over-temperature alarm functions to ensure experimental safety.
Modular design of glass components for easy disassembly, installation, and cleaning.
Optional anti-splash evaporating flasks, receiving flask drain valves, etc., to enhance operational convenience and safety.

Stable & Durable Structure:

The main structure is made of high-quality stainless steel and aluminum alloy, with a powder-coated surface for corrosion resistance and durability.
Precision transmission system ensures low noise, stable operation, and a long service life.
Compact design saves laboratory space.

Diversified Configurations:

Offers a variety of evaporating flask sizes (from 0.25L to 100L, covering laboratory to pilot scales) and receiving flasks.
Customizable special glass components or upgraded configurations (such as diaphragm vacuum pumps, low-temperature cooling liquid circulating pumps, etc.) are available according to user needs.

1. High-Efficiency Concentration: Under vacuum and heating conditions, the solvent's boiling point is lowered, and the evaporation rate is significantly increased, greatly shortening concentration time.

2. Gentle Processing: Particularly suitable for the concentration, crystallization, and separation of heat-sensitive substances, avoiding damage to the target product from high temperatures.

3. High Solvent Recovery Rate: The precision-designed condensation system effectively recovers most solvents, reducing waste, lowering costs, and complying with environmental requirements.

4. Easy and Safe Operation: Both novices and experienced operators can quickly learn to use it; multiple safety protection measures ensure the safety of the experimental process.

5. Good Result Reproducibility: Precise control of parameters (temperature, rotation speed, vacuum level) ensures the stability and repeatability of experimental results.

6. Wide Applicability: Can handle solvents and samples with different viscosities and boiling points, meeting diverse experimental needs.

7. Low Maintenance Cost: High-quality components and durable design reduce maintenance frequency and costs.
