LV-T5 Visible spectrophotometer

A spectrophotometer is commonly used for the measurement of transmittance or reflectance of solutions, transparent or opaque solids, such as polished glass, or gases. In chemistry, spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.

Spectrophotometry is often used in measurements of enzyme activities, determinations of protein concentrations, determinations of enzymatic kinetic constants, and measurements of ligand binding reactions. The use of spectrophotometers spans various scientific fields, such as physics, materials science, chemistry, biochemistry, Chemical Engineering, and molecular biology.

LABOAO is proud to introduce the T5 series of visible spectrophotometers based on the STM32 embedded computer. The series uses advanced color touch screen technology and keyboard parallel input mode for easier operation and higher reliability. Combining our more than 20 years of manufacturing and customer service experience in the spectrophotometer product industry, regardless of optical system design, mechanical structural design, electronic circuit design, software interface and functional design, or product manufacturing process level, production process quality Control, after-sales service efficiency, etc., have reached the international advanced level in the industry.

1. 4.3-inch color touch screen technology and keyboard parallel input mode, easy to operate.

2. Navigation menu design, testing is simpler and easier to use.

Built-in photometric measurement, quantitative measurement, qualitative measurement, time measurement, multi-wavelength measurement, GLP-specific program;

3. U disk data export, USB connection computer

4. A variety of accessories are optional:5-10cm optical path cuvette holder, automatic sample holder, peristaltic pump autosampler, water thermostatic sample holder, peltier thermostat sample holder and other accessories.


1. Photometric measurement: You can select the single-point test wavelength and test method you need in the range of 320-1100nm to measure the absorbance or transmittance of the sample. The concentration of the sample can also be read directly by entering the standard concentration or concentration factor.

2. Quantitative measurement: Measure the sample solution of unknown concentration by curve of known parameter factor or automatically establish standard solution curve; have first-order, first-order zero-crossing, second-order, third-order curve fitting, and single-wavelength correction, double Absorption correction such as wavelength, three-point method is optional; standard curve can be stored and recalled;

3. Qualitative measurement: Set a wavelength range, scan interval, and then measure the absorbance, transmittance, reflectance, and energy of the solid or liquid sample at intervals. It is also possible to scale, smooth, filter, detect valleys, save, print, etc. the already measured maps;

4. Time measurement: Time measurement is also called dynamic measurement. The sample is scanned according to the time range of absorbance or transmittance according to the set wavelength point. The absorbance can also be converted into concentration or reaction rate by input concentration factor.

Enzyme kinetic reaction rate calculation. A variety of map processing methods such as scaling, smoothing, filtering, peak-to-valley detection, and derivation are available for you to choose from;

5. Multi-wavelength measurement: It is possible to set up to 30 wavelength points and measure the absorbance or transmittance of the sample solution.

6. Auxiliary function: accumulative time of tungsten lamp lighting, independent turning off and on of tungsten lamp, operation language selection (Chinese, English), automatic wavelength calibration.
