FAQ

What types of reactors are there?

Single-layer glass reaction kettle, double-layer glass reaction kettle, triple-layer glass reaction kettle, crystallization reaction kettle, lifting reaction kettle, stainless steel reaction kettle, the above types can be customized to explosion-proof reaction kettle (optional).

What are the capacities of glass reactors?

Our glass reactors are available in 1L, 2L, 3L, 5L, 10L, 20L, 30L, 50L, 100L, 150L, 200L (maximum capacity).

What are the common supporting equipment for reactors?

The double-layer reactor can be equipped with high and low temperature pumps, high temperature oil baths, cryogenic pumps and vacuum pumps. The single-layer reactor can be equipped with cryogenic pumps and vacuum pumps.

4.What is the difference between single, double and triple layer glass reactors?

Single-layer glass reactor consists of a single-layer glass container. It is often used for simple chemical reactions, such as stirring, heating and cooling of solutions, and is widely used in laboratory research and small-scale production. The double-layer glass reactor is composed of two glass containers. The inner container is used for the mixing and reaction process of the reactants, while the outer container is used for heating and coolant circulation, which can better control the reaction temperature and maintain a constant Reaction conditions. The triple-layer glass reactor is composed of three-layer glass containers. It is based on the double-layer glass reactor and adds a layer of glass container for vacuuming. It can keep the materials in the kettle as cool as possible under the vacuum state of the outermost layer. or heating temperature. Double-layer and triple-layer glass reactors are widely used in medium and large-scale production in pharmaceutical, chemical, food and other fields.

What is the maximum pressure resistance of a glass reactor?

Jacket pressure: maximum 0.04Mpa, which is 0.4kg positive pressure. The glass kettle body is not resistant to positive pressure.

Will the cryogenic pump pressure damage the glass reactor?

The circulating pressure of the cryogenic pump is 0.2Mpa. Because it is cyclic, the pressure is directly pumped out and will not damage the glass reactor.

Can PH be measured in a glass reactor?

It can be customized, and the PH port can be increased by covering the glass reactor above 5L.

What are the shapes of the stirring paddles of glass reactors?

There are anchor paddles, inclined blade paddles, propeller paddles or frame paddles for mixing. The choice of the form of the stirring paddle depends on the aggregation state of the materials in the kettle, the viscosity of the materials, the amount of the materials, and the ratio of the gas, liquid, and solid phases. At present, the stirring paddles of glass reactors are mostly made of polytetrafluoroethylene (easy to clean and will not pollute materials) and stainless steel.

What are the advantages of glass lifting reactor?

The glass lifting reaction kettle makes it more convenient to observe the reaction process. The height and angle of the reaction kettle can be adjusted as needed, improving the flexibility and efficiency of the experiment.

How to speed up the heating rate of glass reactor?

1. Choose special thermal insulation cotton to wrap the double-layer glass reactor to achieve a thermal insulation effect, which can effectively prevent excessive temperature loss and increase the heating speed. 2. Appropriately increase the set temperature of the high-temperature oil bath (high-temperature circulator) so that the reactor can accept a higher temperature and shorten the heating time. When the reactivity of the double-layer glass is close to the use temperature, lower the temperature of the high-temperature oil bath (high-temperature circulator) to the actual use temperature. 3. Add the solution in the glass reaction kettle in batches. Do not fill it up all at once. This will affect the heating rate. Each time the solution is added, it is about one-half of the capacity. After the temperature rises to close to the set temperature, add more liquid into the kettle. Adding materials can also increase the heating rate!

What is the difference between glass reactor and stainless steel reactor?

Glass reactors are more suitable for chemical synthesis experiments of strong acids and alkalis, but can only withstand negative pressure. Stainless steel reactors can withstand negative pressure and a certain positive pressure, with a greater stirring torque and better stirring effect for viscous materials. The disadvantage is that they have poor resistance to strong acids and alkalis.

How to use jacketed glass reactor with circulating pump?

When reacting under normal temperature and negative pressure conditions, it is recommended that jacketed glass reactor be used with circulating water vacuum pump. When reacting under low temperature and negative pressure conditions, it is recommended that jacketed glass reactor be used with low temperature coolant circulation pump and circulating water vacuum pump. When reacting under high temperature and normal pressure conditions, it is recommended that jacketed glass reactor be used with a high temperature circulating oil bath. When reacting under negative pressure conditions within an ultra-wide temperature range, it is recommended that jacketed glass reactor be used with heater chiller circulation device and circulating water vacuum pump. When reacting under negative pressure conditions within an ultra-wide temperature range and there is a need to collect coolant, it is recommended that jacketed glass reactor be used with heater chiller circulation device, low temperature coolant circulation pump, and circulating water vacuum pump.
