isible spectrophotometer (also known as visible photometer, spectrophotometer) is visible spectrophotometry is Shanghai beauty analysis instrument adopts the latest microcontroller technology, developed to quantitatively measure (standard curve measurement, concentration on the material for direct reading); OD value directly measure (absorbance, transmittance and energy such as direct reading); Dynamic testing (the change of the measured substance concentration change over time OD value); Spectral scan (a kind of material can be whole wavelength scanning, analysis the characteristics of the material wavelength, judge the error of the experimental process); Multiwavelength test (material can be tested multiple wavelength at the same time, the analysis of the relevant material properties); Also can undertake protein/DNA testing total nitrogen, total phosphorus, heavy metals, pesticide residues testing, food safety testing, thermal power generation metal ion test, etc., are widely used in food, medicine, electricity, research, teaching, scientific research, chemical, biological, chemical, quality supervision, environmental protection and water quality inspection and so on various fields. V - 1500 PC visible spectrophotometer, wavelength range: 320 nm to 1100 nm, can meet the test of different material.

Technical parameter:

1. The wavelength range: 200-1000 - nm wavelength repeatability: 0.5 nm

2. The wavelength accuracy: + / - 1.0 nm photometric accuracy: + / - 0.5% T

3. The spectral bandwidth: 2 nm wavelength shows: LCD2 x 20 bit; Accurate to 0.1 nm

4. The stray light: 0.2% or less T 220 nm / 220 nm

5. Stability: 500 nm + / - 0.002 A/hour

Characteristics:

1. With low stray light, the high resolution monochromator, single-beam ensures the accuracy of wavelength, wavelength, repeatability and higher resolution.

2. Automatic tuning 0% 100% T and T, automatically adjustable wavelength and a variety of methods of data processing function.

3. High resolution, wide sample tank, which can hold 100 mm diameter light absorption pool and corresponding reflectance accessory.

4. The instrument is equipped with a standard RS - 232 two-way communication interface, can be an external printer, print the corresponding experimental data.

5. The appearance of personalized design, light touch keys make the operation more convenient.

Introduction:

UV - 2102 - c type UV/visible spectrophotometer

Designed by the United States' parent company. Product has passed ISO9001 quality system certification, domestic measurement conformity certification and the British dB Technology CE certification testing center.

Powerful functions of software, such as: dynamic testing: A: minimum sampling interval 0.5 seconds, maximum running time nine hours

B: set delay time, running time, sampling time interval

C: T/A mode conversion

D: there are computing functions

Multiple wavelength test: A: test wavelength points up to 32

B: more than test samples

Establish standard curve, quantitative test: A: at the same time set up eight points of the standard curve

B: we can do a first order of zero, but zero linear regression and the second order and third order curve fitting

DNA/Protein test: A: manual and automatic testing, test wavelength the default value is 260 nm, 280 nm and 280 nm, can also be modified

B: DNA, Protein and thewire Ratio calculation

Other features: A: test results can be transferred to the data processing in Excel or Word

B: deuterium lamp, tungsten lamp automatic switch and other series.

Procedures:

Boot 

1. before starting, check whether the power socket connected;

2. start the power switch, instrument display "723 c"

3. instrument after self-test, press the "MODE" key and then press "2", instrument display "DATA"

The basic method of use:

1. press the "GO TO lambda" key, set the input wavelength;

2. four color plate, of which R placed reference sample, the remaining three into the sample under test. The colorimetric dish in the sample pool than color dish rack, cover sample pool cover;

3. push the reference sample into the light path, press "ABS %", make the instrument zero and full;

4. then under test sample into the optical path, show that the absorbance of sample values;

5. if you want to to be print out the test sample data, only need to press the "START/STOP" key.

Matters needing attention:

1. a day after use, should check carefully whether the sample indoor solution overflow, overflow must use filter paper at any time if you have any blot;

2. instrument after use, cover with dust.
