To buy rotary evaporator, several factors need to be considered, such as the size, capacity, and functionality of the device. You should also consider your budget and the level of precision and control required for your particular application. It is recommended to do some research and compare prices and specifications of different suppliers before purchasing. Here are some key points:
Rotary Evaporator Applications:
Buying a 10l rotovap should consider the specific application for which you will be using the rotary evaporator.
Solvent removal:
A rotary evaporator can be used to remove organic solvents such as ether, acetone, and methanol. This technique is commonly used in chemical synthesis and pharmaceutical processes to remove reaction solvents and increase yields.
Concentration and Extraction:
Rotary evaporators can also be used to concentrate and extract natural products such as plant extracts, natural flavors and colors, etc. These natural products often need to be extracted from large quantities of raw materials, and the use of rotary evaporators can efficiently concentrate and isolate useful components.
Solubility determination:
Rotary evaporators can be used to determine the solubility of drugs and compounds, which is important for pharmaceutical research and development.
Solution purification:
A rotary evaporator can be used to isolate and purify compounds. This technique is often used to prepare compounds of high purity or to separate components in a mixture.
Rotary Evaporator Capacity:
The size of the evaporating flask is an important consideration when buying a rotary evaporator. You will need to select a flask size that is appropriate for your sample volume.
The capacity of the evaporating flask should be selected according to the sample volume you are processing to ensure that your sample can be fully contained and properly evaporated. Choosing a flask that is too small may result in sample spillage or uneven evaporation during evaporation, while choosing a flask that is too large may waste solvent and reduce evaporation efficiency. When selecting the size of the flask, the maximum rotational speed and maximum volume of the selected rotary evaporator should also be considered to ensure that the capacity of the flask does not exceed its carrying capacity.
FBL’s popular capacities include: 1 L, 2 L, 5L, 10L, 20L, 50L.
Condenser Types For Rotary Evaporators:
When buying a rotary evaporator, the rotary evaporator can have different types of condensers, such as water-cooled condensers or dry ice condensers. Consider which type of condenser is best for your application.
Water-cooled condenser:
A water-cooled condenser is a common type of rotary evaporator condenser that uses tap water or circulating water as the cooling medium. Water-cooled condensers are relatively inexpensive, easy to use, and can handle a certain amount of steam. However, it may not cool as well as a dry ice condenser and also requires periodic water changes and cleaning.
Dry ice condenser:
A dry ice condenser is a highly efficient type of rotary evaporator condenser that uses dry ice as the cooling medium. A dry ice condenser cools the vapor faster, reducing the amount of solvent that evaporates. However, dry ice condensers are more expensive, require more experimental skills to use correctly, and require frequent dry ice replacements.
When buying a rotary evaporator, the appropriate condenser type should be selected according to the experimental needs and budget. If you need to process large quantities of samples or solvents, a dry ice condenser may be a better choice, but has the disadvantages of being extremely costly. If your experimental requirements are not very high, or you want to save costs, then a water-cooled condenser may be a better choice, and the water-cooled condenser has a faster cooling speed.
Purchase Budget:
Rotary evaporator prices vary widely, so it’s important to consider your budget when buying a rotary evaporator. FBL has a variety of rotary evaporators with various capacities and models. The basic model small rotary evaporator RE-201D is usually around a few hundred dollars; while the large, high-end model D-RE-5002 can be anywhere from 3000-5000 dollars.
Therefore, experimental needs and budget need to be considered when selecting a rotary evaporator. If you process a large number of samples or require specific features, such as temperature control or automation, then a higher-end model may be more suitable for you. However, if your experimental needs are not very high, or you want to save money, then the basic model may be more suitable for you.
Manufacturer And Supplier Reputation:
Before purchasing a rotary evaporator, it is important to know the reputation of the manufacturer and supplier. Some well-known manufacturers of rotary evaporators include FBL, etc., which have a good reputation in the field of rotary evaporators and have been widely used and verified.
Also, it is very important to choose a trustworthy supplier. A good supplier should have good customer support and after-sales service, able to provide professional advice and technical support to ensure the use and maintenance of your rotary evaporator.
You can check product specifications, features, and performance, and learn about warranty and support policies, among other things, on the FBL manufacturer’s website. At the same time, we will also hold exhibitions and conferences to communicate with more customer representatives, so that customers can trust and buy our products.
