• Drying Powders

The tool may serve to dry powders. For it to serve this role, it has to be attached to a test tube adapter. Unlike the other approaches, this one does not involve too hectic procedures and approaches. It hence does the job but without the unnecessary hassles which other approaches have to contend with.

• Flavor Extractions

In the food industry, the rotary evaporators may be used to extract flavors. These flavors are subsequently used to adorn other foods and drinks. The tool is yet again quite handy indeed. Unlike its counterparts, it does not at all lead to the loss of flavor in the course of extraction.

• Sample Preparations

When preparing some samples, the rotary evaporator may yet again come in. In particular, this equipment is awesome for the preparation of the High-performance liquid chromatography (HPLC) and a couple of other natural samples. It retains the accuracy and integrity of the samples to yield good results.

• Sample Concentration

Some samples require that the solvents be strongly concentrated. This machine also comes to the rescue. It extracts excess solvents to leave behind a higher concentration of solutes. In this way, the sample becomes more concentrated in such a way as to serve the role which is needed just fine.

• Solvent Removal, Separation, and Recycling

We could go on and on and on had it been possible. Due to the limitations of space and time, we inevitably had to stop there. As you may see, this tool has numerous applications and uses. It is certainly in your best interest to make the most of it.

3. The Benefits of Plant Extraction By Using WKIE Lab Rotary Evaporator

It is good for the extraction of such plants like terpene and cannabinoid extraction. This is works through different processes such as distillation. When it is used to extract raw cannabis, the outcome is called shatter as well as THCA and this is rich in oral formulations. After the extraction process, it can be used to manufacture different things such as tinctures, oils, edibles, and various vaporized concentrates.

Furthermore, it remains the most efficient as well as the best environmentally friendly method of doing away with volatile solvent from such products as non-volatile samples. This is possible because this solvent is reusable and they are recoverable. Because of that, you are going to use to minimize unnecessary wastes and cover overhead expenditure.

During the extraction process, the lipids and waxes are removed from such plants and other desirable products such as cannabinoids and flavonoids as well as terpenes. It is used for that kind of purpose because it is efficient and you are going to use it with reduced or minimal labor. Once it is extracted, the product can be reclaimed. It can reduce the cost of production because it would significantly bring down the cost of production.

The presence of a vacuum in the process is a great advantage because it can enhance the distillation capacity. Moreover, the system pressure and boiling points have shown to be codependent. These can be easily adjusted and when that is done, it makes available that ideal boiling point. Just as you reduce the temperature of the condensation capacity of the product also lowers. When this happens, bumping can result in the process. Inevitably this equally leads to an unnecessary solvent dissipation. It is easy to extract plants through this process and it is widely used more than any other.

Precautions for Rotary Evaporator Use

1. The flask that is collecting the solvent should always be emptied to avoid mixing of chemicals that are not compatible to prevent accidents.

2. The flask containing the solutions should be placed on the rotary evaporator. The bump trap is used to prevent the solutions from splashing into the condenser hence contaminating it. It is advisable always to start the process with a clean bump bulb so that if bumps over happens; the solution or the solid can be recovered.

3. A Keck clip or a metal is used to secure the bump trap or the flask

4. On the monitor, there is a deal, which is used to control the rotation of the flask. The rotavap mostly uses a variable speed between 0 to 220 rpm that is sparkles produced by the spinning motor and provides a high contact torque.

5. The vacuum of the aspirator is turned on and is managed when the stopcock which is on top of the condenser. As well the stopcock is also useful to vent after the solvent has been discharged from the setup

6. The flask is immersed in the water bath when the condenser is tilted; adjustments should be made. The water temperature should be below the boiling point of the solvents. If the solvent is small, the bath heater is not necessary.

7. The solvent is obtained on the condenser as it is collected in the receiving flask. Solvents that are so volatile like dichloromethane and diethyl ether can evaporate in the receiving flask. Liquid nitrogen or dry-ice condenser is used to collect it.

8. When all the solvent has evaporated, you can now release the vacuum. The flask will rise above the water bath, and you can stop the spinning.

9. The bump trap can now be cleaned, and you can empty the receiving flask when the processes of evaporation are over.

How Does A Best Rotary Evaporator Work?

A rotary evaporator is an instrument applied in both biology and chemical used in the laboratories and pilot plants for the evaporation of solvents. A rotary evaporator contains a vacuum system, an evaporation flask that is mechanized to rotate, a condenser and a collecting flask.

A rotary evaporator operates in a principle that the liquid’s boiling point reduces when their pressure is reduced, this allows solvents to vaporize at lower temperatures than operating under the standard boiling points and normal pressure.

The vacuum system can accomplish the whole process by only selecting a vacuum pump that is suitable for the rotavap which will improve the efficiency of evaporation.

The condenser is used to convert the evaporated gas back to its liquid state, here the lowered temperature conditions are necessary. The cooling effect is achieved by the use of cold water, dry ice or by use of liquid nitrogen.

The evaporation flask should be always be rotating to ensure the surface area of the liquid is increased. The surface area should be large enough, then the normal to increase the evaporation rate. When the flask is rotating, the centrifugal force will keep the liquid on the inner surfaces of the flask hence exposing a large surface of the liquid, increases the rate of evaporation.

On the monitor, there is a deal, which is used to control the rotation of the flask. The rotavap mostly uses a variable speed between 0 to 220 rpm that is sparkles produced by the spinning motor and provides a high contact torque.

The rotavap is very efficient and recommendable to remove the majority of organic solvents at the time of the extraction process.

When using a mechanical pump to operate instead of an aspirator to provide a vacuum, the secondary trap should be used to stop the solvent liquid from destroying the membrane.

The heating bath should contain distilled water to reduce the scale from building up in the tub, causing coats around the thermistor. When using water that is not distilled, it will result in the growth of algae colonies mostly during summer months. This can be avoided by exchanging water regularly.

If there are algae growth coats, the condenser has to be removed and then soak the coil by the use of the dilute nitric acid solution by allowing it for a few hours. Then later rinse the rotavap carefully before assembling it.

Rotary Evaporator Bumping Problem

The Problems Come With Rotovap Bumping

Bumping is one of the problems associated with a rotary evaporator. When it bumps it will lead to an unnecessary solvent lost. This shows that just as the process has great advantages that are associated with it, there are also some negative aspects of it as well.

Bumping problems is as bad as the annihilation of substance which is one of the challenges of this process. Other challenges observed in the process include slow evaporation and so on. The main thing here is that these can course more problems to that system if it is handled wisely.

The limitations in the course of its use cannot be avoided. Further research has to go on to find the best ways of handling that limitation. The rotary evaporator concept is not new as the concept has been there for more than five decades. What is new are some of the challenges that are observed. These challenges begin to manifest as the use of the product of that system is intensified.

How To Solve Rotovap Bumping?

The way to address that problem was evolved over them and that brings in the concept of vacuum vortex evaporator. This among other thing ensures to reduce the problem of bumping significantly. When you heat the sample, it is natural that it has to bump as it boils. This simply means that it begins to erupt and this comes with its challenges. When the sample is lost, the user is losing the precious time spent on it as well as money used to secure those samples. This problem is done away with when you apply the vacuum vortex evaporation technology in any smart evaporator.

It is usually stirred and that is done in an airflow based liquid vortex and that is done through steady atmospheric pressure. When this is done, it makes bumping impossible and reduces the problems associated with it which include sample lost and loss of money.

How to Set Up A WKIE Lab Rotary Evaporator

1. Fix the rotating joint ring to the glass rotary joint and leave the tapered edge of the joint ring is facing the driving unit.

2. Slide the rotary joint ring to the driving unit until you hear a click sound when the two parts connect.

3. Pick the two available vacuum seals ( main and semi-vacuum seals) and join them to the rotary joint. The two seals are brown and should face outwards ones connected to the rotary joint.

4. The other step involves the fixing of the rotary joint ring to the driving unit. Make sure to push the joint ring to the driving unit until it snaps.

5. Get the condenser support which is made of metal rod and knob bolt and fix it to the driving unit. Make sure to leave some room for movement in case you need to turn it.

6. Attach the glass trap manifold to the driving unit. The glass trap is quite fragile; hence, you should fit slowly as it can break and even injure you. Don’t force it to the unit.

7. Attach the condenser column to the trap manifold and ensure the coil inlet and outlet are facing outward. (note that this fitting is recommended for those with type V and T Condenser). If you are using type S Condenser, fix it directly to the driving unit while the coil inlet and outlet are facing upwards.

8. For Condenser V and T, attach the condenser clamp to the supporting rod. Ensure to tighten the clamp hook around the condenser clamp and finish off by connecting it to one of the holes near the screw set. For ample fitting of the Condenser, tighten the set screw and knob bolt. Note that this step is not ideal for type S Condenser.

9. Attach the flask which formed in a spherical shape to the trap manifold using the ball joint clip. If you are using type S, connect it directly to Condenser.

10. Using the joint clip, fix the evaporating flask to the rotary joint.

11. The next step involves the fitting of the capillary feed tube. This is done through the trap manifold for the V and T models. The S models use the Condenser to connect the capillary feed tube. Note that the V models come with a glass suction nozzle that should be joined to the top part of the Condenser.

12. Then attach the available water cooling nozzles and the vacuum nozzle to the Condenser. In most cases, the water cooling nozzles come in two pieces.

13. Lastly, place the bath under the evaporating disk.

For an effective evaporation process using the rotary evaporator, use the above steps to help you set it up. Read the manufacturer’s manual to learn about the precautions to take when handling the available parts of the device.
