Spectrophotometer

PRODUCT DESCRIPTION

MODEL: SPM23 Spectrophotometer

Overview

The SPM23 spectrophotometer is a laboratory instrument designed to measure the absorbance or transmittance of light by a sample at specific wavelengths. It is commonly used in chemistry, biology, and environmental science laboratories for quantitative analysis of solutions.

Design and Features:

• Single Beam Configuration: The SPM23 uses a single beam optical system, where light passes through the sample and is detected to determine absorbance.
• Wavelength Range: Typically covers the visible spectrum (around 320–1000 nm), making it suitable for many colorimetric assays.
• Digital Display: Equipped with an LED or LCD screen to show wavelength settings and absorbance/transmittance readings.
• Control Panel: Includes buttons for mode selection (absorbance, transmittance, concentration) and a wavelength adjustment knob.
• Sample Holder: Designed to hold cuvettes, usually 10 mm path length, for liquid samples.

Applications

• Concentration Determination: Used to measure the concentration of solutes in a solution using Beer–Lambert’s law.
• Enzyme Kinetics: Monitoring reaction rates by measuring changes in absorbance over time.
• Quality Control: In industries such as food, beverage, and pharmaceuticals to ensure product consistency.
• Environmental Testing: Measuring pollutants or nutrient levels in water samples.

Advantages

Easy to operate and maintain.

Suitable for routine laboratory analysis.

Cost-effective for educational and small-scale research labs.
