UV-Vis Spectrophotometer / Double Beam UV-VIS

Spectrophotometer model "U-2900/U-2910" :
Standalone double beam Spectrophotometer model U-2900 and PC controlled model U-2910 with fixed band width and silicone photodiode detector

Features :

Eye-catching display : Flexible large colour LCD display (26.4 cm) makes model U-2900 simpler to use and higher in dependability.

Data Storage :
Model U-2900 has space for storing 50 sets of data. For storage of more data, an USB memory stick can be attached.

Incorporation of stigmatic concave diffraction grating : For elimination of the aberrations, a stigmatic concave diffraction grating has been developed by applying Hitachi's original technology for making the grooves on the grating by the only ruling engine in Japan . As a result, a higher resolution has been realized.

PC based Instrument control and data processing : U-2900 can be controlled by a PC equipped with optional UV Solutions Program. U-2910, on the other hand. is the model exclusively for operation with a PC.

Specifications :

Optical system Double beam
Wavelength range 190 to 1,100 nm
Spectral bandpass 1.5 nm
Display U-2900: color LCD with backlight (26.4 cm)
Printer I/F U-2900: Centronics interface

Applications : Model U-2900/2910 can be used to analyse chemical and biological samples in liquid form both qualitatively as well as quantitatively. It can also measure transmittance and absorbance of samples in the form of thin film and glass filter by using appropriate sample holder. Following are few examples of its application -

• Analysis of Phenol, total Phosphate, Silica, Nitrite Ion, etc. in water sample
• Analysis of Free Formaldehyde in Cloth Products
• Analysis of Ethanol in Soy Sauce
• Tannin analysis of tea
• Analysis of L-Glutamin Acid in Sweet Sake
• Measurement of quantity of IR pigment in plastic bottles
