Frequently Asked Questions
1. What is the difference between a Visible and a UV-Vis spectrophotometer?
Visible spectrophotometers measure light in the visible range (approx. 320–1100 nm), while UV-Vis instruments include an additional light source (usually deuterium) to measure absorbance in the ultraviolet range (190–320 nm).
2. Why use micro-volume spectrophotometers?
Micro-volume units are essential for life science applications where sample quantity is limited, allowing for the measurement of as little as 0.5 to 2.0 µL of DNA or protein solution without dilution.
3. Are the BRAND sample beakers compatible with all models?
These beakers are designed for common laboratory sample handling; however, you should always check the sample holder dimensions of your specific spectrophotometer for compatibility.
4. Do these instruments come with calibration certificates?
Most professional benchtop spectrophotometers from Cole-Parmer and Biochrom can be supplied with factory calibration data to ensure compliance with laboratory quality standards.
