What is wiped film evaporator?

Wiped film evaporator is a new type of high-efficiency evaporator which is through a rotary wiper to make a film, and has a high-speed flow, high heat transfer efficiency, short residence time (about 10~50S), and can be used for falling film evaporation under vacuum conditions. 1. Small vacuum pressure drop The vaporized gas of the material is sent from the heating surface to the external condenser, and there is a certain pressure difference. Compared with the general evaporator, the scraper-type thin film evaporator has a large gas traversing space, and the pressure inside the evaporator and inside the condenser are almost equal, so the pressure drop is small. 2. Low operating temperature The evaporation process of the wiped film evaporator can be maintained under a high vacuum degree. Due to the increase of vacuum degree, the corresponding boiling point of material is rapidly reduced, so that the operation can be carried out at a lower temperature to reduce the thermal decomposition...

How much does rotary evaporator cost?

Rotary evaporator has become the best choice for many customers because of its economical price, simple structure and easy operation. It is an ideal equipment for laboratory evaporation /concentration /removal solvent /alcohol recovery. We all want to buy a cheaper rotary evaporator, but many of the equipment that looks very similar from the picture is actually quite different. Let's take a look at what are the points we need to pay attention to when choosing a rotary evaporator? The rotary evaporators are similar, but the quality is different. It is embodied in: glass thickness, electronic component brand, gasket material, workmanship and experience of rotating and lifting parts. These will determine the service life of the rotary evaporator, the system vacuum degree, the corrosion resistance, and the evaporation efficiency,etc. In short, price is one aspect, quality and service are also very important. If you choose a complete set of rotary evaporator equipment, you must consid...

How does a xenon lamp work?

Xenon lamp light source is one of the commonly used light sources for photochemical reaction instruments, it is an electric light source that uses xenon discharge to emit light. Since the discharge material is an inert gas, xenon, there is a small difference between the excitation potential and the ionization potential. Xenon light source application scenarios   1. solar cell IV test.   2. steady-state surface photovoltage spectrometer.   3. photoelectric catalytic test.   4. Quantum efficiency test. Xenon lamp light source is widely used in research fields such as photolysis of water to produce hydrogen, photochemical catalysis, carbon dioxide to methanol, photochemical synthesis, photodegradation of pollutants, water pollution treatment, biological illumination, optical detection, various simulated sunlight acceleration experiments, ultraviolet band acceleration experiments, etc. .

When choose rotary evaporator, we need to consider the glass thickness, electronic component brand, gasket material, workmanship and experience of rotating and lifting parts. These will determine the service life of the rotary evaporator, the system vacuum degree, the corrosion resistance, and the evaporation efficiency,etc. 2. Choose suitable vacuum pump and chiller, if the cooling capacity of the chiller is not enough, the temperature will not stabilize at the set temperature, it will continue to rise, if high pressure protection in summer, and the vacuum pump is small, it will overheat after a long time, and then it...

What are the methods of extracting essential oils?

The process of extracting essential oils is to use steam distillation to extract the materials through water-repellent or co-water distillation. It is suitable for the extraction of conventional oils and aromatic oils from plant branches, leaves, flowers, grasses and animal materials with higher oil content. TOPTION essential oil distillation equipment is widely praised and widely used in universities, research institutes, laboratory research and development departments of enterprises and institutions, and pharmaceutical factories.  What are the methods of extracting essential oils? 1. In water distillation is suitable for some fresh flowers, broken peels and easily bonded raw materials, such as roses, orange blossoms, etc. However, the lipid components in essential oils distilled in water are easily hydrolyzed, so spice plants with high lipid content such as lavender cannot be used.  2. Up water distillation is widely used. A large area of aromatic plants such as peppermint...

How to Crystallize CBD - Make CBD Isolate

CBD crystallization is usually a follow-up process of short-path molecular distillation. The high-purity cbd oil is separated by wiped film molecular distillation equipment, and then passed through the cbd crystallization reactor for heating, stirring, cooling and filtering, and finally high-purity cbd crystals are obtained. In fact, cbd oil can be crystallized at room temperature. The main purpose of artificial crystallization in a crystallization reaction kettle is to obtain high-purity cbd crystals. At this time, the cbd crystals are white. The simple working principle of the crystallization kettle is that the cbd oil and solvent are added to the reaction tank, connected to the heating circulator, and the materials are heated through the interlayer of the reaction kettle, fully mixing. After the mixture is fully mixed, the temperature is cooled by low-temperature equipment to precipitate crystals. The filter plate filters out the crystals, and the mother liquor will be recycled in...
