Medical test tube packaging equipment

Microbiology laboratory staff must have a strict concept of sterility, and many experiments are required to be carried out under aseptic conditions. The main reasons are: first, to prevent the samples from being artificially contaminated during the detection operation; second, to ensure the safety of workers and prevent the detected pathogenic bacteria from causing personal pollution due to improper operation. The requirements are as follows:

1. 1 When inoculating bacteria, you must wear work clothes and work caps;

1.2 When inoculating food samples, you must wear special work clothes, hats and slippers, put them in the buffer room of sterile room, and use them after ultraviolet disinfection before working;

1.3 When inoculating food samples, wash your hands with soap before entering the sterile room, and then wipe your hands with alcohol cotton balls;

1.4 tubes, plates and culture media used for inoculation must be disinfected and sterilized, and unused containers must be unpacked, and cannot be put on hold before use. Metal utensils should be autoclaved or burned with alcohol for three times before use;

1.5 When taking out the pipette from the package, the tip of the pipette should not touch the edge of the test tube or plate;

1.6 Inoculation of samples and transfer of bacteria must be carried out before alcohol lamp. When inoculating live samples of bacteria, the straw should be disinfected with flame after being taken out of the package and the test tube plug is opened;

1.7 5 minutes before inoculation of bacteria, the inoculation ring and needle should burn all metal wires with flame, and if necessary, burn them to the joint of needle and ring and rod. The inoculation ring inoculated with mycobacterium tuberculosis and virulent bacteria should be boiled in boiling water for 5 minutes, and then burned with flame;

1.8 When using a straw to suck bacterial liquid or sample, you should use the corresponding rubber head to suck it, and you are not allowed to suck it directly with your mouth.
