Differences and advantages between micro spectrophotometer and traditional spectrophotometer

K5500 micro spectrophotometer

★The sample volume is required to be large, most of which are 50 μ Above L

★The required sample volume is small, only 1~2 μ L

★Use cuvette

★Do not need a cuvette. Use a pipette gun to directly drop the sample onto the detection platform. During measurement, the sample will automatically form a liquid column

★Every time the sample is changed, the cuvette needs to be cleaned, and the work is heavy

★Just wipe the sample from the test platform with clean absorbent paper

★The optical path is generally 10mm, the sample needs to be diluted, and the measuring concentration range is small

★With two optical paths of 1mm and 0.2mm (regulated by solenoid valve), the sample does not need to be diluted, and the measurement range can reach 50 times of the conventional spectrophotometer

★The lamp source is generally composed of deuterium lamp (UV) and tungsten lamp (visible)

Short life

★Xenon flash lamp as light source

Long service life and stable performance

★It needs to be preheated for more than half an hour

★No preheating is required and can be detected at any time

★Display absorbance value, not concentration value

★When the absorbance value is displayed, the program directly gives the concentration value (nucleic acid, protein and fluorescent dye)

★The instrument is large and heavy

★Small size（21cm×17cm×11cm ），Light weight（1.35kg）
