Key Features of the Extended Range Spectrophotometer
Built for precision in modern chemistry, pharma and life science laboratories.
Extended 190–1100 nm Wavelength Range
Pushes the spectrum from 190 nm to 1100 nm, capturing data at the near-infrared edge for specialised assays beyond the usual 1000 nm limit.±0.8 nm Wavelength Accuracy
With a 2 nm spectral bandwidth and 1200 lines/mm holographic grating, it gives dependable data for protein and nucleic acid measurements.Automatic Wavelength Selection
The instrument sets the wavelength automatically, removing manual dial errors and speeding up measurements.Dual Light Source
A deuterium lamp covers UV and a tungsten halogen lamp covers visible and NIR, for consistent photometric accuracy.
How to Measure Absorbance with a UV-Vis Spectrophotometer
- Warm up and select wavelength: Switch on, let the lamps stabilise, and choose the analytical wavelength (set automatically).
- Blank the instrument: Fill a clean quartz cuvette with the reference solution and zero the absorbance.
- Insert the sample: Place a 10 mm cuvette containing your sample in the compartment.
- Read the result: Record absorbance or %T on the LCD, or send data to a PC over USB.

Frequently Asked Questions
What is the advantage of the extended 190–1100 nm range?
The extended range lets you analyse further into the near-infrared edge, useful for specific quantitative, chemical and specialised pharmaceutical assays that go beyond a 1000 nm limit.
What ensures the wavelength precision of this instrument?
A 1200 lines/mm holographic grating and automatic wavelength selection give ±0.8 nm wavelength accuracy and avoid manual setting errors.
What light sources does this spectrophotometer use?
A deuterium lamp for the ultraviolet range and a tungsten halogen lamp for the visible and near-infrared range.
What is the difference between this model and the 190–1000 nm model?
This model extends the range to 1100 nm and has ±0.8 nm wavelength accuracy, against 190–1000 nm and ±1.0 nm on our advanced single beam model. Both use a 2 nm bandwidth and a 10 mm cuvette compartment.
What is the difference between single beam and double beam UV-Vis?
A single beam instrument uses one light path, so blank and sample are measured in turn. A double beam instrument monitors sample and reference together, reducing drift. Single beam is simpler and more economical for routine work.
Is it compatible with standard cuvettes?
Yes. It accepts standard 10 mm path length cuvettes, including quartz cuvettes for UV measurements.
Can I measure DNA, RNA or protein with it?
Yes, in cuvette volumes, for example A260 for nucleic acids and A280 or colorimetric assays for protein. For 1–2 µL samples, see the EzDrop 1000 or EzDrop 1000C.
Is it suitable for academic and teaching labs?
Yes. The simple digital interface and robust build suit college and university teaching labs while still supporting research and QC work.
Which laboratories use this spectrophotometer?
Pharma QC labs, water and environmental testing labs, hospital and contract testing labs, and college and university laboratories.
What is the UV-Vis single beam spectrophotometer price in India?
Price depends on configuration and quantity. Submit a quotation request and we will send a proposal covering instrument cost, delivery and installation across India.
Do you offer installation, training and AMC?
Yes. Global Bioscience Solutions provides installation, user training, warranty and AMC support across India.
Can this be supplied for tenders and institutional purchases?
Yes. We supply universities, government research facilities and pharma companies and provide institutional quotations on request.
