Photochemical plate reactorIt is a commonly used equipment for laboratory photocatalytic reactions, organic synthesis, and other scenarios. The core provides stable light through a flat light source and is used in conjunction with a reaction plate to achieve efficient reactions. The following are concise and easy to remember operation points to quickly master the standardized process:
1、 Preparation points before operation
Equipment inspection: Place the instrument on a horizontal table, confirm that the power and light source connection wires are normal, and that the reaction plate and sealing gasket are not damaged; Preheat the machine for 5 minutes and check if the light source brightness and temperature display are normal without any errors.
Sample preparation: Prepare the reaction solution according to the experimental requirements, filter and remove impurities (to avoid blocking the reaction plate channel), and ensure that the sample volume matches the reaction plate capacity (not exceeding the maximum scale line).
Accessory cleaning: Wipe the reaction plate and sealing cover with anhydrous ethanol, blow dry and assemble to ensure no oil stains or residual samples, avoiding contamination and affecting the sealing effect.
2、 Key points of core operations
Loading samples: Open the reaction plate cover and slowly inject the prepared samples into the reaction plate channel to avoid the generation of bubbles (bubbles need to be removed with a suction ball); Cover tightly to ensure the buckle is securely fastened and prevent liquid leakage.
Set parameters: Select the light intensity (such as low/medium/high), reaction temperature (normal temperature or heating mode, generally not exceeding 60 ℃), and reaction time on the control panel. After confirming the parameters, start the device.
Start reaction: Press the "Run" button, the light source lights up, and the instrument starts timing; During the reaction process, observe whether the reaction plate leaks liquid and whether the light source is stable. If there are any abnormalities, stop the machine immediately.
End reaction: After reaching the set time, the instrument automatically stops lighting; After the reaction plate has cooled to room temperature (if heated), open the sealing cover and use a pipette to remove the reaction solution for subsequent testing.
3、 Key points for closing after operation
Cleaning and maintenance: Rinse the reaction plate channel with solvent (depending on the nature of the sample), then rinse 2-3 times with distilled water, blow dry and store; Clean the instrument casing and light source surface to remove stains.
Shutdown storage: Turn off the main power and organize the connecting wires; When not in use for a long time, the reaction plate and sealing gasket need to be disassembled and stored separately to prevent moisture. The equipment should be maintained by running it for 10 minutes every month.
4、 Important safety and precision points to remember
When the light source is working, the temperature is high. Do not touch the light source panel to avoid burns; Wear protective goggles during operation to prevent direct sunlight from shining on the eyes.
The reaction plate is made of glass material and should be handled with care to avoid collision and damage; Regularly inspect the sealing gasket and replace it promptly after aging.
The light intensity and reaction time should be strictly set according to the experimental plan. The photocatalytic reaction conditions of different samples vary greatly to avoid improper parameters affecting the experimental results.
