Spectrophotometer

Model: HO-SPE-3000S & HO-SPE-3000S UV
High wave length resolution
Solid, Liquid & Thin film samples

Holmarc’s HO-SPE-3000S & HO-SPE-3000S UV are entry level spectrophotometers suitable for education, research and industrial applications. Unlike other entry level spectrophotometers, it employs classic Czerny - Turner monochromator design, normally available only with advanced models, which ensures low stray light. It uses 1200 lines/mm blazed holographic grating as the dispersion element providing high wavelength resolution. It also employs a sigma delta ADC of 16 bit resolution for photometric measurements, a resolution higher than most of the spectrophotometers available in this price range. A graphics LCD screen is used to plot an absorbance v/s wavelength graph. The data can then be analyzed for peaks and valleys.

Customized accessories are available to address individual application requirements. In a spectrophotometer, the amount of light passing through the sample cell is measured by a photometer. The photometer delivers a voltage signal to the processing unit. The signal changes with the amount of light absorbed by the liquid changes. According to Beer's law, the amount of light absorbed by a medium is proportional to the concentration of the absorbing material or solute present. Thus the concentration of a colored solute in a solution can be determined in the lab by measuring the absorbance of light at a given wavelength.

Scanning Mode Features

    Wavelength range between 380 to 1100nm for Model : SPE-3000S & 190-1100 nm for Model : SPE-3000S UV
    Selectable scan wavelength interval 1 to 50nm
    Live absorbance plot during scanning
    Plot browser to read absorbance values at each wavelength

Customized accessories are available to address individual application requirements. Model SPE-3000S comes with 10 mm path length cuvettes. Cuvettes of smaller path lengths are available as optional accessory.

For most (99%) absorbance measurements 10 mm pathlength cuvettes are suitable. Cuvettes of shorter pathlengths allow the measurement of concentrated samples without dilution.

Optional Accessories
1. Motorized sample rotation stage - $. 784.00
2. Peltier & Sipper system 5 degree to 75 degree - $. 2500.00
