ELISA analyzer classification

ELISA analyzers can be divided into the following categories according to their different designs:

1. Vertical plate ELISA analyzer: This is the earliest ELISA analyzer. An absorbent pad is made in the concave part of the plate. During the measurement, a small drop of liquid sample on the pad is sucked away by a pipette, and a thin film is formed under the drop in the concave part. The value is read by measuring its absorbance.
2. Flat-plate ELISA analyzer: The distance between the strips is larger, about 2 mm. This design makes the temperature of the entire plate more stable than the vertical plate, with a smaller gradient and higher sensitivity.
3. Automatic ELISA analyzer: Its basic working principle is similar to the vertical plate ELISA analyzer mentioned above, but the measurement speed is faster and the operation is simpler.

The above-mentioned types of ELISA analyzers are widely used, mainly in the measurement of enzyme kinetic endpoint reactions in laboratories such as biochemistry, immunology, clinical chemistry and pathology.
