Rotary Evaporator Is a Fast Liquid Sample Concentrator Device

Rotary evaporator is a fast liquid sample concentrator device. Sample in a spherical glass container heating, decompression, and continue rotation to increase the evaporation surface area and speed up the evaporation rate. Rotary evaporator is a widely used instrument in laboratory, which suitable for reflow operation, solvent rapid evaporation and enrichment of trace components. Rotary evaporator coils system can be sealed decompression to 400 to 600 mm Hg; heating the solvent to the boiling point; while the rotation speed for 50 to 160 rev / min, solvent to form a thin film to increase the evaporation area. In addition, under the action of cooler, superheated steam rapid liquefaction and speed up the evaporation rate. The rotary evaporator is mainly used for pharmaceutical, chemical and biopharmaceutical industries for concentration, crystallization, drying, separation and solvent recovery. The working principle is under vacuum condition, heating thermostat and make the constant speed rotation of the rotating bottle, material formed large-area thin-film in the sidewall. Solvent vapor through condenser cooling and recycling in collection bottle, greatly improve the efficiency of evaporation suitable for easy high-temperature decomposition biological products. Structural characteristics: 1. PTFE and rubber composite seals, maintain a high degree of vacuum. 2. Use highly efficient condenser to ensure a high recovery rate. 3. Continuous feed. 4. Reasonable structure and material stress. Mechanical structure made ​​of stainless steel and aluminum, glass parts used in all high-temperature high boron glass. Source: dawn-hz.com
