20L Rotary Evaporator

The 20L rotary evaporator is one of the most outstanding rotary evaporators, which always removes the solvents from the samples typically after reducing the interior pressure. They play important roles in many areas, including chemistry, pharma, and so on. And we will introduce it below.

We are going to look into its finer details in the discussions that follow.

The Structures of 20L Rotary Evaporator

The following are some of the parts and components of the 20-liter rotovap:

1. Condenser

The condenser is the one that cools the hot gas and converts the same to liquids. It comprises a coil that passes through a coolant on which is attached a ‘cold finger.’ It is in the ‘cold finger’ that the coolant mixtures are poured into. Examples of these are acetone and dry ice.

2. Condensate-collecting Flask

This is found at the bottom of the condenser. Its purpose is to catch the distilling solvents after the same has re-condensed. The flask is the one that contains all the end results of a reaction process. It also doubles up as the single largest compartment of the entire packaging.

3. Motor Unit

To operate, the rotary evaporator has to derive its power from the mains electricity. It is the motor unit that furnishes this power output. The motor unit is the one that converts the electrical energy to torque which further fuels the entire system. How the motor is structured determines the overall efficacy of the system.

4. Heated Fluid Bath

Some samples have to be heated before the same may be acted upon. The heated fluid bath is the one that handles this role. It is strong enough and also distributes heat uniformly. Its interior is also spacious and appropriately configured to hold sufficient amounts of reactants and fluids.

The Features of 20L Rotary Evaporator

A standard 20-liter rotary evaporator exhibits the following features:

1. Transparent

This apparatus is entirely made of glass. For this reason, it is very transparent. It hence gives you the leeway to observe and keep accurate track of the progress of reactions as it happens. Through this transparency, you will also be able to know how much of the reactants to make do with at a time.

2. Very Spacious

As its designation implies, the 20L rotary evaporator has a capacity of 20 liters. This capacity is way more than enough for tackling huge quantities of samples. It is also enough to experiment with those samples which cannot fit the ordinary test tubes, pipettes, and burettes.

3. Heat-resistant

Deliberate steps have been made by the manufacturer to make the entire structure resistant to heat. In light of this awesome trait, the appliance is similarly well able to handle and facilitate the explosive reactions with absolute ease. Hardly will it shatter and endanger your life as a result.

4. Powerful

Other than heat resistance, the rotary evaporator is also more powerful. This is mainly made possible by the strong materials and components that make its stature up. These materials are resistant to all forms of potential damages like harsh impacts. They hence guarantee longer lifespans of the appliance altogether.

5. Quiet

Though powered by motors, the 20-liter rotovap is also optimized for quiet operations indeed. This is because it is designed with the needs and comforts of those around or in the laboratory. With these quiet operations come the benefit of maximum comfort and relative peace of mind.

6. Highly Effective

Compared to the other rotovaps, especially those with limited capacity, the 20-liter rotary evaporator is highly effective indeed. That is because it blends the benefits of medium size with the efficacy of a fully-fledged rotary evaporator. With, you may handle some kinds of potent reactions and chemicals without the risks of explosions.

7. Multipurpose

On the whole, the 20-liter rotary evaporator is multipurpose in that it is capable of handling many tasks and purposes. This stems mainly from its tougher construction and relatively higher capacity. It hence goes that settling on this appliance is a sure way of gaining greater returns on investments.

8. Speedy

The 20-liter rotary evaporator also performs the tasks of facilitating the reactions at a much faster rate. It takes a shorter duration of time to do its thing when compared to the other kinds of apparatus of its character. Thus, if you choose to use it, you will get to enjoy the pleasure of not having to wait for too long to get your outcomes.

The Applications of 20L Rotary Evaporator

the applications of 20L rotovap

A 20-liter rotary evaporator is useful for many tasks and purposes.

The following though are the top uses to which it may be devoted:

1. Extraction of Solvents

The primary role of rotary evaporators is to extract solvents from solutions. It typically does this by first and foremost distributing the solution as a thin film across the interiors of a vessel. When the temperature is elevated, the pressure reduces. In doing so, the solvents separate from the rest of the solution.

2. Mixes Reactants

As noted above, the rotary vacuum evaporator has a heated bath fluid. It is in this chamber that you pour the reactants to mix them accordingly. The walls of the rotary evaporator, though made of glass, are very strong and firm. They are subsequently better placed to provide the support necessary to mix all ingredients thoroughly.

3. Reduces Temperatures

In the course of extracting solvents, the rotovap also reduces the temperatures of the solutions concerned. To reduce the temperatures of the solutions, it makes use of the refrigeration liquid. This it passes through the exchanger after which it further decompresses and cools the same. It is this that lowers the temperatures accordingly.

4. Collects the Final Outcomes

A combination of the condenser and the condensate-collecting flask jointly work to collect all the end products in the lab. The former cools the hot vapors to convert the same to liquids whereas the latter collects the solid end results. These they do with your own comfort and convenience in mind.

5. Aids with Recycling

Some samples may require recycling during use. Yet again, the rotavap comes in handy. It basically collects the solvents, traps the same under a vacuum and collects the same for easy re-use later on. Drawing from this recycling capability, the rotary evaporator contributes towards saving your time and resources.

6. Pharmaceutical Industry

This apparatus is extensively used in the pharmaceutical industry. Here, it is used to mix powerful ingredients that are ordinarily difficult to handle by the ordinary kinds of apparatus. Given its potent nature, the rotavapor plays a vital role in enhancing the efficacy of the reactions altogether.
