Choose this model when you want the narrower 2 nm bandwidth over 325–1000 nm. The two other models reach further into the near infrared, to 1100 nm, and are listed with an LCD and USB output, which suits labs that want to read results on screen or pass data to a computer.
What Is the Visible Spectrophotometer Used For?
A spectrophotometer passes light of one selected wavelength through a sample in a cell and compares the light reaching the detector with the light that entered, giving a reading of transmittance or absorbance. For dilute solutions absorbance rises in proportion to concentration at a fixed path length (the Beer–Lambert law), so the instrument is used to find the concentration of coloured solutions against standards and to record how absorbance changes with wavelength.
This laboratory spectrophotometer fits instrumental-analysis practicals in BSc and MSc chemistry, biochemistry and life-science courses, as well as routine analytical work. Its range runs from 325 nm in the near ultraviolet, across the visible band, to 1000 nm in the near infrared. Because a diffraction grating selects the wavelength, measurements are made at a chosen wavelength rather than through a broad colour filter, which is the main practical difference from a filter colorimeter.
What to Specify When Ordering
- Model — this 325–1000 nm, 2 nm bandwidth visible spectrophotometer, or one of the wider-range models compared above.
- Mains supply — the listed supply is AC 220 V ±22 V at 50 Hz; state the voltage and frequency at your site.
- Quantity — the number of instruments for your laboratory, department or tender.
- Other instruments — a colorimeter or further spectrophotometers from the list below can be quoted on the same enquiry.
Frequently Asked Questions
What is this visible spectrophotometer used for?
It measures the transmittance and absorbance of solutions at a selected wavelength between 325 and 1000 nm. Teaching and analytical labs use it to find concentrations against standards and to plot absorption against wavelength.
What are its wavelength range and spectral bandwidth?
The range is 325–1000 nm and the spectral bandwidth is 2 nm, set by a diffraction-grating optical system. Wavelength accuracy is listed as ≤2 nm and wavelength reproducibility as ≤1 nm.
Why does a narrow spectral bandwidth matter?
A narrower bandwidth means the light passing through the sample spans fewer wavelengths, which helps to resolve sharp absorption peaks and reduces deviations from the Beer–Lambert law. A wider bandwidth lets more light through but averages over a broader band.
What power supply does it need?
It runs on AC 220 V ±22 V at 50 Hz ±1 Hz. The net weight is 11.5 kg.
How does it differ from the 325–1100 nm single beam model?
That model extends to 1100 nm with a 4 nm bandwidth, a 4-position holder for 10 mm cells, an LCD and USB output. This instrument covers 325–1000 nm with a 2 nm bandwidth, a 12 V/20 W halogen lamp and a photocell receiver.
What information is needed for an export quotation?
Send the quantity, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling needs, the mains voltage at site and the tender reference if one applies.
Who manufactures this spectrophotometer?
Jain Laboratory Instruments Pvt Ltd, which trades as JLab, makes it at its works in Ambala, Haryana, India and quotes for it as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory instrument and science equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This visible spectrophotometer comes from JLab’s own works rather than from a trader, so universities, analytical labs, dealers and importers deal with the maker directly, and repeat orders and after-sales queries go back to the same source. As an exporter JLab ships worldwide and reaches every region — Senegal in West Africa, Chile in South America, Kazakhstan in Central Asia, Belgium in Western Europe and Vanuatu in Oceania are examples. Institutions buying through a tender can find details on the JLab lab tenders page.
Other Spectrophotometers and Colorimeters
