Main technical parameters of 5B-1 constant temperature digestion instrument:

(1) temperature control range: room temperature -300 C (in particular: temperature refers to the temperature of the block temperature, digestion of sample liquid temperature and the boiling point of the digestive juice).

(2): less than or equal to 2 DEG C temperature stability.

(3) temperature control accuracy: 0.1

(3) digestion hole number: 6 hole aperture: 16mm*65mm diameter, 15mm diameter for digestive tube.

(4) heating power: 300W

(5) temperature control method: microcomputer PID control, LED display, clear and intuitive.

(6) heating part material: aluminum alloy

The other:

1, food sample digestion:

(1) will be moved to the kitchen in a digester heated to 120 DEG C.

(2) a liquid sample (such as liquor, pure water, natural water) to draw a 1-10.0ml (sample to the digestive tube, add three grain of glass beads) digestive tube into the digester 120 DEG. C, heating to nearly dry, adding 1.0ml (digestive juice 240 DEG C and constant temperature digestion to nearly dry, decentralization of cold, constant volume volume were measured).

(3) General Foods (such as wine, beverages, fruit sugar, powder, flour food, porridge, etc.) weigh 0.500-1.000g samples to the digestive tube, joining the three grain of glass beads, add 10.0ml digestive juice, digestive tube into the digester 160 DEG C Digest about 1-3) to digestive juice clarification, 240 DEG C for constant temperature digestion to completely, take down to cold, constant volume to a certain volume were measured.

(4) (such as meat, sausage, soybean oil, milk powder food containing large amounts of fat and sediment, toffee, chocolate, etc.) said take 0.300-0.500g samples to the digestive tube joining three grain of glass beads, add 10ml of digestive juice, digestive tube into the digester 160 DEG C digestion 3h, if the solution has been clarified 240 DEG C and constant temperature digestion to nearly dry, decentralization of cold, constant volume to a certain volume were measured.

2, water sample digestion:

1.00-10.0ml samples to the digestive tube, adding three grain of glass beads, digestive tube into the digester 120 DEG. C, heating to nearly dry, adding digesting agent (add clean water 0.50ml digestive agent, sewage added 2ml digestive agent) and 240 DEG C and constant temperature digestion to nearly dry takes releases cold, constant volume volume is measured.

3, hair sample digestion:

0.200g sample was taken to the digestive tube to add three beads of glass beads to add 5.0ml digestive juice in the digestion apparatus on the digestion of 30min.240 160 degrees Celsius digestion temperature digestion to nearly dry, take down the cold, will hold to a certain volume to be measured.

4, cosmetics digestion:

Take 0.100-0.200g cosmetics to the digestive tube, add three beads of glass beads to add 5-10ml digestive juice, 160 degrees to digest 1-2h to the solution to clarify the temperature of 240 degrees Celsius digestion to nearly dry, take down the cold, will hold a certain volume of determination.

Note on the use of 5B-1 constant temperature digestion instrument:

1, before use, please face to wipe clean, water, dirt, dirt and other foreign matter residues does not allow it.

2, placing the sample test tube.

3, switch on the power, close the power switch, indicator light, (set the desired temperature value), the instrument is in the working state.

4, when the instrument is in working condition, should be specially assigned to take care of.

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

6, to be working surface cooling, according to the requirements of processing.

7, in order to ensure safety, the use of three eye with the safety of the power supply!

8, test tube samples can not be too much, so as to avoid boiling overflow, damage instrument.

9, do not work should be cut off the power, so as to avoid accident!
