Glass reactor laboratory is an experimental equipment widely used in chemical laboratories, mainly used in mixing, heating, reaction, distillation and other experimental processes. It is usually made of high temperature and corrosion resistant glass material with good chemical stability and durability.
Types of glass reactor laboratory:
Made of one layer of glass, it is generally used for small experiments or research, and its capacity is usually between a few milliliters and a few liters.
Made of two layers of glass with a gap between the inner and outer layers, it can be used for heating, cooling and vacuum operation, and the capacity is usually between several liters and tens of liters.
(3) Triple-layer glass reactor:
It is made of three layers of glass. Generally, the inner, outer and middle layers of glass have different materials. For example, the inner layer is made of acid and alkali resistant glass, the outer layer is made of ordinary glass, and the middle layer is thicker, which can achieve better heat preservation effect.
The difference of glass reactor laboratory:
1. Structure:
The single-layer glass reactor has only one layer of glass shell, which is usually simpler and has a smaller volume, and is generally used for small-scale laboratory tests. The double-layer glass reactor is composed of two layers of glass shells, with a certain distance between the inner and outer layers, and a vacuum or air layer in the middle, which can better insulate and protect the reactor, and has a larger volume. It is generally used for Medium-scale experiments or preparations.
2. Function:
Single-layer glass reactors can usually only complete simple reactions, such as dissolving, mixing, heating, etc. The double-layer reactor can carry out various complex reactions such as heating, cooling, vacuum and pressure operation through the inner reactor to meet higher-level experiment and preparation needs.
Why choose glass reactor laboratory?
Each feature of glass reactor laboratory has its unique advantages, and can be flexibly selected and applied according to actual needs. Whether it is preparing chemicals, metal-organic framework materials, or polymer materials, glass reactor laboratory can provide an efficient, safe and stable reaction environment for experiments, and promote the smooth progress of experiments.
1. Good chemical stability:
The glass reactor laboratory is made of high-temperature-resistant and corrosion-resistant glass material, which has good chemical stability and is not easily corroded and polluted by chemical reagents.
In the synthesis reaction of preparing metal-organic framework materials (MOFs), the reactor needs to withstand the corrosion and pollution of various organic substances and inorganic acids and bases, and the glass reactor laboratory can meet this demand. In this process, the use of glass reactor laboratory can ensure the purity and stability of the reaction medium and avoid contamination of reagents or side reactions.
2. Good transparency:
The glass reactor laboratory has good transparency, and can visually observe the changes in the reaction process, which is convenient for experimental operation and data recording.
When preparing chemicals, it is necessary to observe and monitor the reaction process in order to adjust the reaction conditions and record the reaction data in time. At this time, the glass reactor laboratory allows the experimenter to directly observe the reaction color, gas generation and other changes, which is convenient for experimental operation and data recording.
3. Easy to clean:
The surface of glass reactor laboratory is smooth, not easy to adhere to substances, and easy to clean and maintain.
In the preparation of organic pharmaceuticals, the reactants are usually toxic organic substances, which put forward higher requirements for the cleaning and maintenance of the reactor. In this process, the smooth surface and chemically inert material of the glass reactor laboratory can ensure that the reactor is easy to clean and maintain, effectively avoiding the residue of reactants and by-products.
4. High security:
The glass reactor laboratory has good heat resistance and pressure resistance, can carry out high temperature and high pressure experiments, and is not easy to burst and rupture, and has high safety.
When preparing polymer materials, the reaction needs to be carried out under high temperature and high pressure. The high heat resistance and high pressure resistance of the glass reactor laboratory can ensure that the reactor will not burst and rupture, effectively protecting the lives and property of experimenters.
5. The cost is relatively low:
Compared with reactors made of other materials, the cost of glass reactor laboratory is relatively low, and it is easy to purchase and replace.
Maintenance:
The glass reactor laboratory is a common reaction vessel in the laboratory. In order to prolong its service life and ensure the accuracy of the experiment, regular maintenance and maintenance are required. The following are the maintenance precautions for glass reactor laboratory:
Cleaning and maintenance:
Before using the glass reactor laboratory, it needs to be cleaned and maintained. When cleaning, use neutral detergent and warm water, and avoid using strong acid and alkali solutions and hard objects to avoid scratching the kettle body.
Shockproof and dropproof:
The glass reactor laboratory needs to be placed on a stable table, and avoid placing it in a place that is easy to shake and bump, so as to avoid collision and vibration that may cause the kettle to break.
Keep away from light:
When storing the glass reactor laboratory, avoid direct exposure to strong light for a long time, so as to avoid aging and deformation of the kettle body due to the action of ultraviolet light.
Periodic inspection:
During the use of glass reactor laboratory, it is necessary to regularly check whether there are cracks, bumps, deformation and other damages. If found, stop using it immediately and replace it in time.
Maintenance:
For the glass reactor laboratory, which is frequently used and has high operating intensity, it is necessary to carry out regular maintenance such as maintenance, replacement of seals, refueling, lubrication, etc., to ensure the tightness and stability of the kettle body.
