50 Liter Rotary Evaporator

The temperature of the environment directly affects the evaporation rate and effect of the sample in the process of rotary evaporation. Higher temperature can accelerate the evaporation rate, but it also increases the risk of sample volatilization. Lower temperature may lead to too slow evaporation rate and prolong the experimental time.

Humidity will affect the volatility and evaporation rate of the sample. Higher humidity will reduce the volatility of the sample, thus slowing down the evaporation rate. Lower humidity is helpful to accelerate the evaporation rate, but it may also lead to premature drying and curing of the sample.

The atmosphere during evaporation plays a key role in the evaporation and collection of samples. In some experiments, it is necessary to control the gas composition and flow rate of evaporation environment to ensure the purity and collection effect of samples.

Good air circulation can help to eliminate harmful gases and evaporants produced in the evaporation process and maintain the safety of the operating environment. At the same time, air flow also helps to reduce the temperature and humidity gradient and reduce the premature curing of the sample on the surface of the rotating bottle.

In some cases, the rotary evaporator may need to be operated under specific pressure conditions to control the volatilization rate and boiling point of the sample. Adjusting the system pressure can change the volatile dynamic behavior of the sample and affect the reaction process.

This is a common type of rotary flask, with a round bottom and good stability and uniform heating ability. Round bottom bottles are suitable for most rotary evaporator operations and can be used for various sample types.

Extraction flask usually has a long neck design, which is convenient for connecting other equipment, such as condenser and reflux device. This kind of bottle is often used for solvent extraction or liquid separation during reaction.

Different from round-bottom flask, the bottom of flat-bottom flask is flat, which is suitable for reaction or evaporation process with large contact area. They have a larger surface area, so the solvent or reaction product can be evaporated more quickly.

This flask is generally equipped for use in rotary evaporators. They usually have special joints to be fixed on the clamping device of the rotary evaporator. The rotary evaporation bottle can be used for various solvent evaporation and concentration applications.

A multi-neck flask has multiple necks, which is suitable for experiments that need to connect multiple accessories or perform multi-step operations. The multi-port bottle can be connected with condenser, stirrer, feeding tube and other equipment at the same time, which improves the experimental efficiency.

Water bath is the most common type of bath, which uses water to heat and cool the operating sample. The temperature range of water bath pot is narrow, usually between room temperature and 100℃, but it can provide stable and uniform temperature and low operating cost.

Oil bath uses oil substances (such as silicone oil, high-temperature hot water, organic oil, etc.) to heat and cool the sample, which has a wider temperature range and better heat conduction performance. The oil bath pot can usually be heated at about 400℃ above room temperature, which is suitable for experiments at high temperature.

Salt bath is a kind of high-temperature bath, which uses high-melting-point salts to raise the temperature. Because of its high thermal conductivity, it can be heated at about 1200℃ above room temperature. Salt bath pots are widely used for heat treatment of metal materials.

The cooling bath usually uses substances such as sodium bicarbonate or ammonium chloride to cool the sample. They are usually used in experiments where the heat generated in the reaction process needs to be cooled quickly.

The air flow bath heats and cools the sample by providing air flow. Because it does not contact the sample, there are fewer restrictions on the sample material and chemical reaction, and the bath pot is widely used in experiments that need to control the sample temperature quickly.
