Introduction
A manual lifting rotary evaporator is a laboratory instrument used for the efficient and gentle evaporation of solvents from samples under reduced pressure, with the evaporation flask raised and lowered by a manual lifting mechanism, and it is widely used in chemistry, pharmaceutical, and food laboratories for concentration, purification, and solvent recovery. In operation, the sample solution is placed in a round-bottom flask that is attached to the apparatus, the flask is partially immersed in a heated water bath, and the system is connected to a vacuum source, which lowers the boiling point of the solvent so that it evaporates at a lower temperature, protecting heat-sensitive compounds; the flask is rotated by a motor, spreading the liquid as a thin film on the flask wall, which increases the surface area and accelerates evaporation, and the evaporated solvent vapor passes through a condenser, where it is cooled and collected as liquid in a receiving flask, allowing the solvent to be recovered and the sample to be concentrated. The manual lifting mechanism allows the operator to raise and lower the flask by hand, making it easy to adjust the immersion depth and to remove the flask, and the instrument is simpler and more economical than automatic lifting models. Manual lifting rotary evaporators are used for solvent removal, for concentration of extracts and reaction mixtures, for sample preparation, for purification, for crystallization, and for solvent recovery, in chemistry, biochemistry, pharmaceutical, natural product, and food laboratories. Features include adjustable rotation speed, temperature-controlled water bath, vacuum connection, and durable construction. With their efficiency and gentle evaporation, manual lifting rotary evaporators are essential for solvent evaporation in laboratories.

FAQ
Q1: What testing scenarios is this evaporator mainly applied to?
A: The manual lifting rotary evaporator is used in chemistry, pharmaceutical research, biological analysis, food testing, environmental laboratories and educational institutions to remove solvents from samples by evaporation under reduced pressure with rotation. It supports solvent removal from chemical synthesis products, concentration of extracts and solutions, sample preparation for analysis, solvent recycling, educational chemistry demonstrations, and general laboratory evaporation. The manual lift provides a simple, reliable mechanism for raising and lowering the rotating flask into and out of the heating bath, with the rotation creating a thin film for efficient evaporation under vacuum. It is essential for chemistry, pharmaceutical, biological and educational laboratories requiring solvent evaporation for sample concentration, product isolation, extract preparation, solvent removal and research, where rotary evaporation provides efficient, gentle solvent removal under vacuum for heat-sensitive samples, supporting chemical synthesis, natural product extraction, pharmaceutical research, environmental analysis and educational applications in laboratory settings.
Q2: What standards does the evaporator comply with?
A: The manual lifting rotary evaporator complies with relevant IEC 61010 laboratory electrical safety standards and applicable GB/T standards for laboratory evaporation equipment. Glassware follows ISO and ASTM standards for laboratory glass. Users should verify vacuum and temperature ratings for their applications. Safety features including over-temperature protection should be verified.
Q3: What is the warranty period for the whole machine and key components?
A: The motor, lift mechanism, bath, controller and stand are covered by a 12-month warranty. The glassware (evaporating flask, condenser, receiving flask), vacuum seal and tubing are consumables or accessories not covered against breakage. Damage from improper use, glassware breakage or unauthorized repair is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained laboratory personnel familiar with rotary evaporation, vacuum systems and chemical safety. We provide an operation manual and remote guidance. Proper glassware assembly, vacuum control, bath temperature setting, rotation speed and manual lift operation are important for safe, efficient evaporation.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular maintenance required? What is the recommended calibration cycle?
A: Vacuum seal inspection and replacement per usage or when vacuum leaks occur. Glassware inspection for cracks before each use. Bath fluid level and quality checked regularly. Motor and lift mechanism lubricated per manufacturer schedule. Routine cleaning of glassware recommended. No formal metrological calibration is typically required beyond temperature verification.
Q7: Are supporting consumables universal?
A: Glassware, vacuum seals, tubing, vacuum pump oil and bath fluid are available from multiple laboratory suppliers, though glassware joint sizes should match the instrument. Long-term consumable cost is moderate depending on usage and glassware breakage.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes evaporating flask size, bath type (water or oil), condenser type, vacuum pump, rotation speed range and accessories. Additional glassware, pumps and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the rotary evaporator and glassware with an operation manual. On-site installation and training are not included for standard orders but can be arranged for laboratory setup. Remote guidance is provided.
Q10: What types of samples are compatible with this equipment?
A: The rotary evaporator removes solvents from liquid samples within the flask capacity, temperature range and vacuum capability. Highly volatile or flammable solvents require proper fume hood use and cold trap protection. High-boiling solvents may require oil bath and higher vacuum. Heat-sensitive samples require lower bath temperatures. Users should select appropriate flask size (fill no more than half), use proper vacuum pump and cold trap for solvent recovery, control bath temperature below solvent boiling point under vacuum, ensure proper glassware assembly and vacuum seal, never leave operating unattended, and follow proper chemical safety procedures including eye protection and fume hood use. The manual lift should be operated carefully to avoid glassware contact with the bath or spillage.
