Embodiment 1
[0040] ①Preparation of working solution: prepare different concentrations and types of antibiotic solutions or biochemical working solutions required, and add non-ionic surfactant with HLB value of 3.0 to 20.0 during the preparation process;
[0041] ② Adding samples: add the prepared solution to the blank test card, and the amount added to each well is 25 μl;
[0042] ③ Pre-cooling: Put the test card that has added the sample into the partition of the drying box, close the door, cool the partition, and reduce the temperature of the product to 2-4 °C;
[0043] ④ Preliminary drying: Turn on the vacuum pump and nitrogen gas permeation switch, and set the program parameters according to the following procedures.
[0044]
[0045]
[0046] ⑤ Analyze and dry, close the nitrogen control solenoid valve, turn on the vacuum pump, and pump the vacuum to below 100Pa for 1 hour.
[0047] ⑥Packing: Vacuum-packed products in aluminum foil bags.
[0048] ⑦The entire drying time is no...
