Description
Technical Parameters
The 10 liter rotovap is mainly used for large-scale solvent removal and sample concentration, and is suitable for chemical synthesis, drug preparation, natural product extraction and other laboratory work that needs to deal with a large number of reaction solutions or samples. The equipment can quickly and efficiently remove the solvent from the reaction solution by rotating the bottle under the action of constant temperature water bath or constant temperature heater, and at the same time, it can recover the removed solvent and concentrate the sample.
Product Information
The reaction in a 10 liter rotovap is usually heated in different ways according to its characteristics and needs:
● Suitable reaction for water bath heating
For reactants with high solvent volatility and low boiling point, such as ether and acetone, water bath heating can be selected. This is because the boiling point of water is relatively low, which will not lead to overheating of reactants and avoid possible combustion or deterioration.
For some temperature-sensitive reactants, such as some biological agents or compounds with poor temperature stability, water bath heating can also be chosen, because water bath heating is relatively mild and it is not easy for reactants to be affected by excessive temperature.
● Suitable reaction of oil bath heating
For some reactants with high boiling point, such as some high-grade solvents and liquid reagents, oil bath heating can be selected. Because the boiling point of oil is much higher than that of water, it can provide a higher working temperature range and is suitable for dealing with reactants with high boiling point.
For some reactions that need long-term continuous heating, oil bath heating can provide more stable and lasting heating effect, which is conducive to controlling reaction conditions and continuous operation.
Product Types
If you are looking for a 10 liter rotovap, there are two lifting methods: manual lifting and electric lifting.
● 10L manual lifting rotary evaporator: The lifting principle of manual lifting rotary evaporator is based on mechanical transmission structure, usually using worm and worm gear structure. The user drives the worm wheel by manually rotating the worm, thus realizing the function of up-and-down lifting. The lifting component is a lifting bracket or a lifting frame, which can be lifted up and down through the worm and worm wheel structure.
● 10L electric lifting rotary evaporator: The electric lifting rotary evaporator is a screw transmission structure driven by a motor. When lifting is needed, the motor is started to drive the screw to rotate, and the pitch of the screw will push the nut to move up and down, thus driving the lifting frame to lift up and down.
The 10L rotovap equipment is suitable for many pilot-scale reactions.
● Esterification reaction: Esterification reaction is the process of reacting acid with alcohol to form ester. For example, acetic acid reacts with ethanol to produce ethyl acetate. After the reaction is completed, the residual solvent and water can be removed by using rotary evaporator machine to obtain a pure ester product.
● Etherification reaction: Etherification reaction is the process of reacting alcohol with etherifying agent to produce ether. For example, phenol reacts with methanol to produce toluene ether. Using 10L rotary evaporator system, the reaction mixture can be concentrated, and the remaining solvent and water can be removed to obtain pure ether products.
● Acylation reaction: Acylation reaction is the process of reacting acid with alcohol or amine to form ester or amide. For example, benzoic acid reacts with aniline to form benzamide. The residual solvent and water can be removed by using a rotary evaporator, and pure amide products can be obtained.
● Hydrogenation: Hydrogenation is a process in which unsaturated compounds react with hydrogen to produce saturated compounds. For example, styrene reacts with hydrogen to produce ethylbenzene. After the reaction is completed, the residual solvent and unreacted hydrogen can be removed by using a chemical rotovap to obtain pure saturated compound products.
● Ketone synthesis reaction: Ketone synthesis reaction is the process of reacting aldehyde with alcohol to produce ketone. For example, propionaldehyde reacts with isopropanol to produce acetone. Using a rotary evaporator, the reaction mixture can be concentrated, and the remaining solvent and water can be removed to obtain pure ketone products.
Operational Procedure
Operating a 10-liter rotovap involves a series of well-defined steps. Here's a simplified guide to the process:
● Preparation: Ensure that the rotovap is properly assembled and that all necessary components, such as the flask, condenser, and vacuum system, are in place. Fill the water bath with the appropriate amount of water or solvent and set the desired temperature.
● Sample Loading: Pour the sample and solvent mixture into the flask, ensuring that it does not exceed the recommended fill level. Secure the flask to the rotovap using the appropriate clamps or adapters.
● Adjusting Parameters: Set the desired rotation speed, heating temperature, and vacuum level based on the requirements of your sample.
● Starting the Process: Turn on the rotovap and allow it to reach the set temperature. Gradually increase the vacuum level until the desired level is achieved. Monitor the process carefully, adjusting the parameters as needed.
● Monitoring and Collection: As the solvent evaporates, the vapor will condense in the condenser and collect in the receiving flask. Monitor the process periodically, ensuring that the receiving flask does not overflow.
● Stopping the Process: Once all the solvent has been removed, turn off the rotovap and gradually release the vacuum. Remove the flask from the rotovap and transfer the concentrated sample to a clean container.
● Cleanup: Clean the rotovap and its components thoroughly after each use to prevent cross-contamination and maintain optimal performance.
Product Package
Problems needing attention in packaging and transportation of 10 liter rotovap.
● Packaging requirements: When packaging, we should choose solid packaging materials, such as foam board, foam plastic, cardboard, etc., to protect the equipment from vibration and collision. In addition, it is necessary to use suitable fillers to fix the equipment to prevent it from moving or rubbing during transportation.
● Packaging of accessories: In addition to the main engine, the accessories need to be packaged separately to prevent the accessories from colliding with each other and causing damage. All accessories should be properly packaged and clearly marked in the package for identification and use during transportation and installation.
● Mode of transportation: Choosing a suitable mode of transportation is a very important step. Due to the large size and heavy weight of the equipment, sea transportation or land transportation is usually chosen. For international transportation, special attention should be paid to customs duties, customs clearance procedures and other matters.
● Moisture-proof and shockproof: Special attention should be paid to moisture-proof and shockproof measures during transportation. Avoid prolonged exposure to humid environment, and at the same time avoid severe vibration or bumps, so as not to damage the equipment or cause internal parts to fall off.
● Insurance and supervision: During transportation, it is recommended to purchase appropriate cargo insurance to deal with accidental damage or loss. At the same time, for international transportation, it is necessary to follow the relevant import regulations and regulations of the destination country or region, and go through customs clearance procedures to ensure the smooth entry of equipment.
