Product Details

Scientific instruments are tools for precision measurement, and their precision and reliability must be an order of magnitude higher than the object being measured. Therefore, although there are not as many components as airplanes, the systematic design is also beyond imagination. The chromatographic column, as a consumable, is a separation center, just like the heart. High pressure, tightness and flow rate stability are required. And the oven needs to be kept at a constant temperature. To prevent leakage, maintain constant temperature, pressurized flow, every link, can not be slack. For materials, seals, and fluid mechanics, a high foundation is required.

The method for checking whether the instrument leaks: pinch off the external vacuum skin tube, and observe whether the vacuum gauge on the instrument can keep the instrument leak-free for five minutes. If there is air leakage, check whether the sealing ring on each sealing joint and rotating shaft is effective. On the contrary, the instrument is normal to check the vacuum pump and vacuum pipeline.

F3-10L automatic lifting three-layer glass reactor

Model: F3-10L

Features: The F3-10L automatic lifting three-layer glass reactor has an electric constant speed stirring system, condensation and dropping system, and the interlayer in the kettle body needs to be externally connected with heating or cooling circulation equipment. The interlayer outside the kettle needs to be externally connected with vacuum equipment to maintain vacuum to keep the temperature of the materials in the kettle warm.

Working principle

This machine has an electric constant speed stirring system, condensation and dropping system. The interlayer in the kettle needs external heating or cooling circulation equipment. The interlayer outside the kettle needs external vacuum equipment to maintain vacuum to keep the temperature of the materials in the kettle.

While stirring the materials, the circulating hot solution or cooling liquid is injected through the inner interlayer to heat or cool the materials in the kettle at a constant temperature. When the material is heated, the evaporation efficiency can be improved under vacuum conditions (vacuum device needs to be connected). The solvent vapor is cooled into liquid when passing through the glass condensing coil (cooling device needs to be connected), which can be returned to the kettle or recovered through the valve at the lower part of the reflux elbow. After the reaction is completed, the materials can be discharged from the side discharge port at the bottom of the kettle.

The lifting and rotating reaction kettle is based on the common reaction kettle, which can make the kettle cover and the part above the kettle cover rise as a whole. After the stirring rod leaves the kettle body, the kettle body can rotate 150 degrees to the left through the hand wheel to directly pour out the materials, which is convenient for cleaning the kettle body.

This series of products use the need to support the vacuum device, high temperature or low temperature circulation device and other components of the system device.

Basic configuration

• The glass is high borosilicate glass (expansion coefficient 3.3), which can be used in the range of high temperature (250 ℃) to low temperature (-80 ℃).

The kettle body is made of three layers of glass, forming an inner interlayer and an outer interlayer. The inner interlayer is filled with cold and hot circulating liquid, and the outer interlayer is vacuumed to keep the temperature of the materials in the kettle.

• The main bracket is made of square steel anti-corrosion plastic-sprayed aluminum alloy stainless steel.

• The kettle cover is made of PTFE.

The kettle cover and the part above the kettle cover can be raised and lowered electrically, and the kettle body can be rotated 150 degrees to the left by hand wheel.

• Glass PTFE discharge valve, no liquid side discharge.

After the jacket inlet and outlet ports are connected with stainless steel hoses, they are fixed to the bracket and then connected with the external circulating pipe to reduce the inlet and outlet hydraulic pressure and avoid damage to the connecting part of the glass interlayer circulating port and the circulating pipe.

Low-speed booster motor, frequency conversion speed regulation, through the rotary fine adjustment, double display speed control box can digitally display the speed and the temperature of the material in the kettle.

The mixing system adopts ceramic bearing and mechanical seal to prevent the mixing rod from wearing off chips.

• Using PT100 temperature sensor, 304 stainless steel, transparent Teflon tube jacket, double anti-corrosion.

• Vacuum pressure gauge shows real-time vacuum, pointer display.

• Crescent-type stirring paddle, 304 stainless steel PTFE stirring blade; Stirring rod is made of 304 stainless steel, outer PTFE tube.

• The bottom of the machine is equipped with a brake Fuma universal wheel, which can move as a whole and is easy to operate.

• Stirring, lifting fuse safety protection.
