Spectrophotometer vs spectrometer
Spectrophotometers and spectrometers are two commonly used analytical tools in chemistry, physics, and biology labs. While both instruments measure the interaction of light with matter, there are some key differences between them. One of the main differences is the wavelength range that each instrument can measure. Spectrophotometers usually measure within a specific range of wavelengths, typically from 190 nm to 1100 nm, while spectrometers have a broader range that can extend into the ultraviolet or infrared regions.
But the main difference is that spectrometers measure the radiated matter of light, while spectrophotometry measures the color it creates. Spectrophotometers are otherwise known as UV-Vis spectrophotometers.
Another important factor to consider when choosing between these instruments is portability. Spectrophotometers are typically smaller and more portable than spectrometers. They are often used for simple analyses like measuring absorbance or transmittance in solutions or determining protein concentration in samples. On the other hand, spectrometers tend to be larger and more complex devices that require specialized training to operate effectively.
What does UV-vis lab spectrophotometer mean?
The UV–vis simply means Ultraviolet-visible spectrophotometer. Nothing else.
Advantages of UV-vis spectrophotometer
Spectrophotometers are analytical instruments that measure the intensity of light as a function of wavelength. The instrument is used to measure the amount of light absorbed by a sample to determine its chemical or physical properties. One common type of spectrophotometer is the UV-Vis spectrophotometer, which uses ultraviolet and visible light to analyze samples.
The advantages of using a UV-Vis spectrophotometer include:
- It’s high accuracy and sensitivity.
- Ease of use
- Ability to perform rapid measurements.
- The instrument can detect even small changes in absorbance, making it ideal for analyzing trace amounts of substances.
- Modern detectors used in UV-Vis spectrophotometers provide excellent signal-to-noise ratios for precise measurements.
Another advantage is the versatility provided by different types of detectors such as photodiodes or CCDs (charge-coupled devices).
How to use spectrophotometry?
Spectrophotometry is a powerful analytical technique used to measure the amount of light absorbed or transmitted by a sample. Spectrophotometers measure the intensity of light at different wavelengths, allowing scientists to determine the chemical composition and concentration of a substance. This technique is widely used in many fields, including chemistry, biology, and environmental science.
To use spectrophotometry effectively, it’s essential first to calibrate your instrument. Calibration ensures that your measurements are accurate and reliable. To do this, use a reference material with known properties or prepare your own calibration standards using solutions of known concentrations. Once you’ve calibrated your instrument correctly, you’re ready to start making measurements.
When using spectrophotometry for color measurement applications such as in printing or textile industries it’s important to standardize lighting conditions for accurate results.

#4. Techne 6705 UV/Visible Spectrophotometer
The Techne Model 6705 is the best spectrophotometer for those looking to operate in a large commercial environment.
The Model 6705 is certainly a popular model in the industry and has a 190 to 1100nm wavelength range, a 4nm spectral bandwidth, and a xenon lamp.
We find that the 4nm bandwidth provides more consistent results for low-concentration samples and prefer it over the 1nm bandwidth for almost everything.
Finally, just note that the Techne 6705 provides multi-user login and password protection for up to ten users, which is a nice feature to have at a corporation.
