Background introduction:


Digestion instrument is a commonly used sample preparation equipment, according to the degree of automation can be divided into semi-automatic digestion apparatus and automatic digestion apparatus; according to the principle can be divided into electric digestion apparatus and microwave digestion apparatus, there are relatively mature products, the application is very widely.


The digestion instrument can be applied to sample preparation of various analytical chemistry such as digestion, extraction, protein hydrolysis and so on. Sheng Aohua series intelligent digestion instrument has been more and more used in water quality testing pretreatment experiments, replacing traditional electric furnace heating, saving time and effort, greatly improving work efficiency.

Use and maintenance:


1. Please wipe the working surface of the COD constant temperature digestion instrument before use. Do not allow water droplets, dirt, scale and other foreign matter to remain on the COD thermostat.


2. Place the sample tube.


3. Turn on the power, turn off the power switch, the indicator light is on (set the required temperature value), the COD constant temperature digestion instrument is in working state.


4. When the COD constant temperature digestion instrument is in working state, it should be the person in charge.


5. After the work is completed, turn off the power switch and cut off the power.


6. After the working surface has cooled down, treat it as needed.


 


Features:


1. Fast digestion, high efficiency, energy saving


2. Special cooling system, shell temperature ℃, COD thermostat digester has longer service life and is safer


3. Excellent thermal insulation performance, good thermal insulation effect, up to 5 hours after power off


4. Fast heating speed, up to 150°C in 15 minutes, uniform temperature


5. The COD constant temperature digestion instrument adopts a new temperature control program and a special heating method to make the temperature difference between the holes less than ±0.5°C


6. Convenient operation program, more convenient and safer to use.
