1. Opening and closing the instrument
Before using laboratory equipment, you must first check the manual of the equipment and have a certain understanding of the functional characteristics and operation procedures of the equipment. For common laboratory instruments, opening and closing are generally carried out in the following steps:
1. Manual instrument: first turn on the power switch of the instrument, then press the start switch, and wait for the instrument to start normally before performing subsequent operations; when closing, first press the stop switch, and then turn off the power switch.
2. Automatic instrument: first connect the instrument to the power supply, set the parameters correctly according to the manual, then press the start key, wait for the instrument to start normally, and then perform subsequent operations; when closing, first stop the operation of the machine, and then shut down the equipment correctly according to the manual.
2. Operation sequence
When using laboratory equipment for experiments, be sure to operate in the correct order to avoid deviations in experimental results due to improper operation. The specific operation steps are as follows:
1. Install the equipment: According to the manual of the instrument, correctly install the equipment so that it is placed stably and will not cause harm to surrounding instruments or personnel.
2. Preliminary preparation: Before conducting the experiment, prepare the materials, reagents and instruments required for the experiment, and perform preliminary preparations such as sample preparation and calibration according to the instructions.
3. Operation process: When conducting the experiment, follow the correct operation process and conduct the experiment strictly in accordance with the requirements.
4. Post-processing: After the experiment is completed, post-processing should be carried out according to the instructions, including cleaning, disinfection, maintenance, etc.
III. Safety precautions
When using laboratory equipment, always pay attention to safety issues to avoid accidents caused by improper operation. Specific safety precautions are as follows:
1. Wear protection: When conducting experiments, wear protective clothing, gloves, goggles and other protective equipment to protect your safety.
2. Avoid confusion: When using instruments, clarify the functions and operation procedures of the equipment to avoid improper operation due to confusion and cause danger.
3. Comply with regulations: Strictly abide by the regulations of the laboratory and do not change the equipment settings and operation procedures without permission.
4. Emergency handling: When equipment failure or improper operation causes safety hazards, emergency measures should be taken in a timely manner to protect the safety of laboratory personnel and equipment.
