Lin Bo, deputy mayor of Quanzhou, attended the report meeting on the comprehensive rectification work of the building stone industry in Quanzhou.
The inspection team went to Jinjiang and Anxi to conduct special inspections and listened to reports on the work of Quanzhou. The inspection team fully affirmed the achievements of the comprehensive rectification work of the building stone industry in Quanzhou. In recent years, Quanzhou has listed the comprehensive renovation of the architectural veneer stone industry as an important part of the comprehensive remediation of water environment in key river basins, and has been included in the annual assessment of environmental protection objectives. Comprehensively carried out the work of building facing stone mining and rectification, the scale control of processing enterprises, the construction of processing concentrated areas and the comprehensive utilization of building facing stone waste (slag), and achieved results. In the next step, Quanzhou will also speed up the construction of stone processing concentrated areas, increase the construction of environmental protection infrastructure, accelerate the ecological restoration of key mining areas, vigorously promote the use of new wall materials, and comprehensively promote the transformation and upgrading of the building facing stone industry.
Rotary Evaporator is an indispensable instrument for the process of evaporation, concentration, crystallization, drying, separation and solvent recovery in the scientific research and production process of the pharmaceutical, chemical and biological products industry.
It is generally combined with the vacuum pump, chiller and other instruments.
The rotary evaporator is developed by constant temperature heating and thin film evaporation under vacuum negative pressure condition. The rotating evaporator rotates the glass rotating bottle at a constant speed with stepless speed regulation, the material forms a large area uniform film in the bottle wall, and then the rotating bottle is evenly heated by the intelligent constant temperature water bath. The high speed evaporation is made under the vacuum condition. The solvent vapour is cooled by the high efficiency glass condenser and recycled to the collecting bottle. The rotary evaporator works in the vacuum condition, and the high temperature and high boron silicon glass and polytetrafluoroethylene are used in the contact part of the material. It is especially suitable for the concentration and purification of the biologics which are easily decomposed at high temperature.
The company supports customized rotary evaporators, such as explosion-proof, voltage and so on.
The rotary evaporator is divided into manual lifting and automatic lifting. Users can choose according to the situation.
Capacity: 1L, 2L, 3L, 5L, 10L, 20L, 30L, 50L, 100L, Short path distillation,
wiped film distillation
