Specifications
Model RAY-723N Visible Spectrophotometer is an intelligent product with single-chip microprocessor control technology so that it has many sophisticated functions possessed by large high-end instruments and can meet the requirements of qualitative and quantitative tests for most samples conducted in conventional laboratories. The instrument is widely used in medical and health, Clinical examination, biochemical, petroleum chemical, environmental protection and quality control departments, etc. The instrument with a low price and high performance is your best choice.
Main Characteristics
The instrument adopts a 5.8" LCD graphic display and an externally linked thermal sensitive printer as its display and output devices to give a clear display of test results and prompts during the operation procedures. The thermal sensitive printer can easily print out test results for making data report and retention.
Test method offers photometric mode, wavelength scanning, quantitative analysis and dynamical analysis and multi-wavelength test mode. In the quantitative test mode, three normal analytical methods of factor input, single-point and undetermined multiple-point are offered.
Unique cell-matching function eliminates measurement errors caused by cell-matching (effective only in the photometric mode and quantitative analysis).
It has the function of automatic zero and full scale adjustment.
It is highly accurate in measurement reading and excellent in repeatability and stability.
The instrument has many advanced functions such as concentration direct reading, linear regression, timing print, GOTOλ And spectrum scanning and the like.
Sampling at different wavelength intervals of 0.1nm, 0.2nm, 0.5nm, 1nm, 2nm and 4nm can be made according to users' requirements.

Spin Flash Dryer is continuous drying cake, cream paste,slurry materials,have rotary vortex air current with mechanical mixer.
Flash Dryer is continuous drying equipment specially designed for shaped cake, cream paste, paste slurry materials. Clean heat medium goes into the drying room from the tangent direction, form a strong rotary vortex air current together with mechanical mixer. Wet material has been added to the drying room in a fix quantity, and stir in the vortex of air currents were crushed under dry. Drying room at the top with particle size classification, the fine powder discharged from the top of the tower from the back of the separator to collect the product into larger particles return to the drying room, continue to be crushed, and dry.
The hot air enters into the bottom of the dryer in tangent direction. Under the driving of the stirrer,a powerful rotating wind area is formed. The paste state materials enter into the dryer through the screw charger.Under the powerful function effect of stirring at high-speed rotation,the materials are distributed under the function of s trike,friction and shearing force. The block state materials will soon be smashed and contact the hot air fully and the materials are heated and dried. The dried materials after the de-watering will go up with the hot-air flow. The grading rings will stop and keep the big particles. Small particles will be discharged out of the dryer from the ring center and will be collected in the cyclone and dust collector.
