Electric vibrating screen operating procedures

Electric vibrating screen operating procedures

1. The electric vibrating screen must be placed horizontally on a stable and solid foundation.

2. Before starting the machine, check whether the fixed condition of each machine is in good condition and whether the motor rotation is normal.

3. Pour a good amount of the sample into the sieve supplier Hebei Dahong Experimental Instrument Co., Ltd., fix the sieve on the vibrating screen machine, and start the vibration shake.

4. After use, turn off the power and remove the sieve.

Electric vibrating screen and clean the instrument, fill in the instrument usage record.

The COVID-19 Antigen Test Cassette is immunoassay based on qualitative membrane strip for the detection of COVID-19 antigen in anterior nasal swab

specimen. In this test procedure, anti-COVID-19-N antibody is immobilized in the test line region of the device. After an anterior nasal swab specimen is placed

in the specimen well, it reacts with anti-COVID-19-N antibody coated particles that have been applied to the specimen pad. This mixture migrates chromatographically along the length of the test strip and interacts with the immobilized anti-COVID-19 antibody. If the specimen contains COVID-19 antigen, a colored line will appear in the test line region, indicating a positive result. If the specimen does not contain COVID-19 antigen, a colored line will not appear in this region, indicating a negative result.To serve as a procedural control, a colored line will always appear in the control line region, indicating that proper volume of specimen has been added and membrane wicking has occurred.
