A leading pharmaceutical laboratory based in Vietnam sought to upgrade its solvent recovery and sample concentration capabilities to meet growing R&D demands. After extensive market research and supplier evaluation, the client selected Nantong Sanjing Chemglass Co., Ltd as their equipment partner, importing a complete vacuum rotary evaporator system for their pharmaceutical processing workflow. The procurement decision was driven by the manufacturer's proven track record, comprehensive product portfolio, and competitive value proposition in the international chemical glass equipment market.
Nantong Sanjing Chemglass Co., Ltd is one of the largest professional manufacturers of chemical glass equipment in China. The company specializes in the design, production, and manufacturing of biological and chemical testing instruments and pharmaceutical glass equipment. Their main product categories include glass reactor series, rotary evaporators, chemical glass pipes, glass condenser series, glass reaction devices, bath pots, heating circulators, thermostatic baths, cooling circulators, constant speed stirrers, water circulation vacuum pumps, and lab consumables. These products are widely used across the pharmaceuticals, chemicals, biological pharmacy, new materials, and noble metals industries. Beyond manufacturing, Nantong Sanjing Chemglass provides comprehensive services including industry-specific design, equipment selection, instrument supporting, installation, debugging, and maintenance.
The rotary evaporator is an indispensable laboratory instrument primarily used for evaporation, concentration, crystallization, drying, separation, and solvent recovery in the medicine, chemical engineering, and biopharmacy industries. Developed on the principle of thermostat heating that enables thin-film evaporation under vacuum negative pressure conditions, this equipment represents a cornerstone technology for modern chemical laboratories and industrial R&D facilities worldwide.
The rotary evaporator employs stepless speed regulation to rotate a glass bottle at a constant speed. As the bottle rotates, the material forms a large-area, balanced thin film on the inner wall of the bottle. A smart thermostat-controlled water bath heats the rotating bottle, facilitating high-speed evaporation under vacuum conditions. The solvent vapor is then cooled by a high-efficiency glass condenser and recovered into a receiving flask. This cyclical process ensures maximum solvent recovery efficiency while maintaining sample integrity throughout the operation.
For safe international transportation to Vietnam, the glass components of the rotary evaporator were carefully wrapped with protective foam and placed in sturdy cartons, while the main body was securely packed in wooden cases. Both neutral and customized packaging options are available to meet various customer requirements and branding preferences. Multiple shipping options were provided, including international express services such as DHL, UPS, TNT, and EMS, allowing the Vietnamese client to select the most suitable method based on their timeline and budget.
