I. Summary

Thank you for your purchasing and using of TANK Microwave

Digestion System. We appreciate your trust and will try our best to

serve you.

As a kind of sample pretreatment technology, microwave digestion

emerged in the middle of 1980s. Since the advantages of fast

heating rate, homogeneous heating, low blank and energy saving,

microwave digestion has been widely used in the heavy metal

element analysis of foodstuffs, environmental samples, human body

or animal samples, agricultural products, Chinese herbal medicine

samples, textiles, alloy, cosmetics and mineral samples.

Adopting double magnetrons of industrial grade and non pulse

frequency conversion control technology, TANK Microwave

Digestion System achieves rapid and complete digestion of

inorganic or organic samples under the condition of high

temperature and high press. Fiber optic sensor (FOS) guarantees

real-time feedback of temperature and pressure acts as the

monitoring index. Besides, other safety measures are adopted to

guarantee the system’s safe and steady operation.(This manual

applies to model PRO、Basic、ECO )

Characteristics of TANK Microwave Digestion System

1. Steady and efficient digestion capability

2. More humanized operation interface

3. Reliable performance

4. High security

Service Environment

1. Keep away from heat source and avoid hot gas and vapour

entering the system lest causing stoppage. Besides, stay away from

water source to avoid leakage caused by splash.

2. Place it on a firm and stable table. The experiment table shall be

vibration-free and has the ability to bear 75kg at least. No cover on

the left and the right sides of the furnace body, as well as the

top.More than 50cm’s interspace (30cm in back wall) shall be left to

keep good ventilation.

3.Keep away from strong magnetic material and electrical appliance

with magnetism to avoid heating efficiency reduction caused by

magnetic field interference inside of the furnace.

4.Power supply is AC 220V/50Hz. Earth connection shall be

confirmed by wireman since imperfect earth connection may cause

machine breakdown. Earth resistance is less than 4 ohm.

Independent regulated power supply over 4000W shall be equipped,

with the voltage fluctuation less than 10V.

5.Be close to fuming cupboard and other ventilating devices.

6.The required operating temperature is 0 ℃ ～ 40 ℃and the

humidity 10～85%. The best operating temperature is 20℃ ～ 25℃

and the humidity 40～60%.

7.Install exhaust duct before using.

Open-package inspection

1．Seal off the transport case carefully.

Notes: keep instrument packing cases for later transportation.

2．Lift up the instrument with at least two persons and place it on the

experiment table. Check instrument and its components according

to packing list. Please contact retailer or manufacturer if there are

any mistakes, incomplete or abnormal components.

Special Warning

1. Please read this manual carefully for safety and smooth

experiment. When the user is not familiar with similar instrument,

foundation training is required.

2. The actual number of digestion tank shall consist with the set

value of digestion program. Error shall be less than 2 tanks.

3. Perchloric acid is prohibited using digest samples

4. Observe the temperature variation carefully when using

concentrated sulfuric acid to digest samples.

5. Digestion of flammable and explosive material is prohibited. (refer

to Notes)

6. Dry running is prohibited.

7. Safekeeping the manual and transfer it if operator changes.

8. The company reserves the right of product upgrade and changes

the manual content without notice.
