Frequently Asked Questions About the Spectrophotometer
1. What is the difference between a single beam and a double beam UV-VIS spectrophotometer?
A single beam UV VIS spectrophotometer passes light through the sample and reference separately, one after another, while a double beam spectrophotometer measures both simultaneously for better baseline stability during long scans.
2. What is the wavelength range of Yatherm's single beam UV VIS spectrophotometer?
It covers 190.0 to 1000.0 nm with a resolution of 0.1 nm, controlled by a microprocessor-controlled stepper motor.
3. What is an atomic absorption spectrophotometer (AAS) used for?
An AAS is used to measure the concentration of specific metal elements in a sample using flame or hollow cathode lamp-based atomic absorption.
4. What applications use a dual beam UV spectrophotometer?
Dual beam UV spectrophotometers are used in chemical, pharmaceutical, agricultural, biotechnological, hospital, and research laboratory settings for accurate spectrophotometric analysis.
5. What is a microplate spectrophotometer used for?
A microplate spectrophotometer, or microplate reader, measures absorbance across 96-well to 384-well plates for DNA, RNA and protein analysis with minimal manual effort.
6. Which Nano model should I choose for nucleic acid quantification?
The NANO series (NANO 100, 300, 400A, 500) measures nucleic acid concentration from as little as 0.5-2.0 microlitres; the NANO 500 detects nucleic acid up to 15000 ng/ul, the widest range in the series.
7. What is the price of a UV-VIS spectrophotometer in India?
Pricing depends on whether you choose a single beam, double beam, AAS, dual beam or microplate model. Contact Yatherm Scientific, a trusted spectrophotometer manufacturer in India, for the current price list.
8. Does Yatherm provide warranty and spare parts for its spectrophotometers?
