This is the JLab model to choose when methods need the far ultraviolet: the deuterium lamp extends the range down to 190 nm, and it lists the tightest wavelength accuracy and the lowest stray light of the four. The 325–1100 nm model shares the 4 nm bandwidth and large compartment for work that starts in the near ultraviolet, while the 335–1000 nm and 400–1000 nm models suit routine teaching colorimetry.
What Is the 190-1100nm UV-Visible Spectrophotometer Used For?
A UV-visible spectrophotometer measures how much light a sample absorbs at each wavelength. Here the deuterium lamp supplies the ultraviolet region and the tungsten lamp the visible and near-infrared region, so one instrument covers 190 to 1100 nm. The Littrow grating selects a 4 nm band, the light passes through the cuvette, and the silicon photodiode measures what is transmitted; absorbance then relates to concentration through the Beer–Lambert law. With the optional PC software the instrument scans spectra at up to 2000 nm per minute.
The ultraviolet range opens up work that visible-only instruments cannot do: direct absorbance readings of nucleic acids and proteins in biotechnology and molecular biology, identification and assay of organic compounds and drugs in pharmacy and chemistry labs, and UV methods in water and environmental testing. Quantitative analysis and multi-wavelength tests are built in, the four-position holder carries a blank and standards, and long-path cuvettes up to 100 mm help with dilute samples. Readings in the ultraviolet need cuvettes that transmit UV light, such as quartz cells, because ordinary glass absorbs there.
What to Specify When Ordering
- Whether you want the optional PC scanning software.
- The path lengths of the cuvettes you plan to use, from 5 to 100 mm.
- The number of instruments required for your laboratories.
Frequently Asked Questions
What wavelength range does this spectrophotometer cover?
190 to 1100 nm, with a 4 nm spectral bandwidth, ± 0.8 nm wavelength accuracy and repeatability of 0.3 nm or better.
Which lamps does it use?
A tungsten lamp and a deuterium lamp, both pre-aligned and placed for easy replacement.
Can it scan a full spectrum?
Yes, under PC control with the optional scanning software, at up to 2000 nm per minute, with baseline flatness of ± 0.002 A.
What cuvettes does it accept?
Cuvettes from 5 to 100 mm path length, with a four-position holder for 10 mm cells. For ultraviolet readings the cuvettes must transmit UV light, which ordinary glass does not.
How does it differ from the 325–1100 nm model?
It adds a deuterium lamp, so the range starts at 190 nm instead of 325 nm, and it lists tighter wavelength accuracy (± 0.8 nm against ± 1.0 nm) and lower stray light.
What should an export enquiry include?
The number of instruments, whether you need the scanning software, the destination country and port or city, delivery terms such as FOB or CIF, packing or labelling requirements, and the tender reference if the order is for a tender.
Who manufactures this UV-visible spectrophotometer?
Jain Laboratory Instruments Pvt Ltd (JLab) builds it at its works in Ambala, Haryana, India, and supplies it direct.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory instrument manufacturer in India, incorporated in 2017 with premises on Hargolal Road, Ambala, Haryana. The spectrophotometer is produced in JLab’s own works and not sourced from a trader, so universities, research and testing labs, dealers and importers buy from the maker directly, every unit is visually inspected before dispatch, and repeat orders are handled by the same manufacturer. JLab exports worldwide and ships to buyers in every region — for example Iceland in Northern Europe, Guatemala in Central America and the Caribbean, Sudan in North Africa, Ukraine in Eastern Europe and Mexico in North America. Tender information is on the JLab lab tenders page.
