Here are the common operating guidelines for laboratory photoreactors in English:

General Operating Guidelines for Laboratory Photoreactors

1. Pre-Operation Preparation

• Equipment Check: Ensure all components of the photoreactor are intact and securely connected. Verify that the light source is functioning correctly and that the optical path is unobstructed.

• Reactant Preparation: Accurately weigh and prepare reactants according to experimental requirements. Ensure the purity and stability of the reactants meet the experimental standards.

• Safety Measures: Wear appropriate personal protective equipment, such as lab coats, gloves, and safety goggles. Ensure the laboratory is well-ventilated and that emergency equipment (e.g., fire extinguishers, eye wash stations) is readily available.

2. Operating Procedures

• Reactor Assembly: Add reactants to the photoreactor as per experimental instructions. Securely attach the reactor lid to ensure a good seal.

• Light Source Settings: Adjust the intensity and wavelength of the light source according to experimental needs. Ensure that the light source evenly illuminates the interior of the reactor.

• Reaction Condition Control: Set the reactor's temperature, pressure, and stirring speed based on experimental requirements. Monitor temperature changes during the reaction to ensure it proceeds within a safe range.

• Reaction Process Monitoring: Regularly observe the reactor's operating status, including light source performance and stirring uniformity. Collect samples during the reaction for analysis as needed.

3. Post-Reaction Handling

• Product Collection: After the reaction ends, collect the product as specified in the experimental protocol. Purify and characterize the product if necessary.

• Equipment Cleaning: Clean the photoreactor and its accessories promptly after use. Ensure the cleaned equipment is dry and free of residues.

• Data Processing: Organize and analyze experimental data to draw conclusions. Compare experimental results with expected outcomes to assess the effectiveness of the experiment.

4. Safety and Precautions

• Priority on Safety: Always prioritize safety during operations. Follow laboratory safety regulations to ensure personal and equipment safety.

• Precise Operations: Be precise when weighing and preparing reactants. Strictly control reaction conditions to ensure the accuracy of experimental results.

• Timely Documentation: Record experimental data, observations, and anomalies in a timely manner. Ensure the completeness and traceability of experimental records.

• Equipment Maintenance: Regularly maintain and service the photoreactor to ensure its performance and accuracy meet experimental requirements.

By adhering to these guidelines, researchers can ensure the safe and effective use of laboratory photoreactors for their experimental needs.
