How Does It Compare with Other JLab Spectrophotometers?
| Model | Optical system | Cell holder | Bandwidth | Wavelength accuracy | Weight |
|---|---|---|---|---|---|
| This spectrophotometer (EL-LE-8259) | Double beam, Littrow (1200 lines/mm) | Two single-position, 10 mm cells | 2 nm | ± 0.3 nm | 44 lb |
| Split Beam Spectrophotometer Wavelength Range 190-1100nm | Littrow (1200 lines/mm) | Four-position, 10 mm cells | 2 nm | ± 0.3 nm | 42 lb |
| Single Spectrophotometer Wavelength Range 190-1100nm | Single beam, Littrow (1200 lines/mm) | Four-position, 10 mm cells | 4 nm | ± 0.8 nm | 32 lb |

Choose the double beam model when you want sample and reference measured in their own holders, for example during long kinetics runs or spectrum scans. The Split Beam model has the same range, bandwidth, touchscreen and wireless links but a four-position cell holder in place of the two single-position holders. The two single-beam models list a 4 nm bandwidth and a large LCD with key panel, and the 325–1100 nm model works with a tungsten lamp only.
What Is the Double Beam Spectrophotometer Used For?
It measures light absorption by solutions across the ultraviolet, visible and near-infrared: the deuterium lamp supplies the ultraviolet and the tungsten lamp the visible and near-infrared. In a double-beam layout the light is divided between the sample and a reference, and the instrument works from the ratio of the two readings, which reduces the effect of lamp drift on long measurements. The listing names college, university and general laboratory settings.
The built-in functions cover basic photometric readings, quantitative analysis (concentration from standards through the Beer–Lambert relationship), kinetics tests that follow a reaction over time, and multi-wavelength tests at up to 32 wavelengths. With the optional PC scanning software it records absorbance spectra at up to 2000 nm per minute. Measurements below the visible range need UV-transmitting cuvettes such as quartz, because ordinary glass absorbs ultraviolet light.
What to Specify When Ordering
- Cell holder arrangement — this double beam model with two single-position holders, or the Split Beam model with a four-position holder.
- Whether the optional PC scanning software should be quoted.
- The number of instruments needed (minimum order 10 units) and the delivery destination.
Frequently Asked Questions
What does the double-beam design do?
It divides the light between the sample cell and a reference, so each reading is a ratio of the two. This reduces the effect of lamp drift, which helps on kinetics runs and spectrum scans.
What cell holders and cuvette sizes does it take?
Two single-position holders for 10 mm cells. The large sample compartment accommodates cuvettes from 5 to 100 mm path length.
How precise is the wavelength setting?
Wavelength accuracy is ± 0.3 nm and repeatability 0.1 nm or better, with a 2 nm spectral bandwidth and stray light of 0.05% T or less at 220 nm and 360 nm.
Can results be exported?
Yes. The Android-based software saves to USB storage through the USB port and connects over Wi-Fi and Bluetooth; optional PC software adds spectrum scanning at high, medium or low speed.
How is it different from the Split Beam Spectrophotometer 190-1100nm?
The two listings share the range, bandwidth, accuracy, touchscreen and connectivity. This model is listed as double beam with two single-position holders and weighs 44 lb; the Split Beam model has a four-position holder and weighs 42 lb.
What are its size, weight and power needs?
It measures 21.5 x 18.5 x 10.3 inches, weighs 44 lb and runs on AC 90–250 V at 50/60 Hz.
What should an export quotation request include?
The quantity, whether PC scanning software is required, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), packing or labelling instructions, and any tender reference.
Who manufactures it?
JLab — Jain Laboratory Instruments Pvt Ltd — makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory instrument manufacturer in India incorporated in 2017, with its works and office on Hargolal Road, Ambala, Haryana. This double beam spectrophotometer comes from that works, not from a trading house, so universities, colleges, analytical labs, dealers and importers order it factory-direct; every instrument is visually inspected before dispatch, and repeat supplies come from the same manufacturer. JLab exports worldwide and ships to buyers in every region — for example Fiji in Oceania, Angola in Central Africa, the Maldives in South Asia, Ivory Coast in West Africa and the Netherlands in Western Europe. For institutional purchasing, see the JLab lab tenders page.
