How Does It Compare with Other JLab Spectrophotometers?
| Model | Wavelength range | Bandwidth or slit | Readings | Other listed details |
|---|---|---|---|---|
| This spectrophotometer (EL-LE-8253) | 335–1000 nm | 10 nm slit width | Absorbance, transmittance, factor, concentration | Automatic zeroing, one-touch blanking; ± 1% T; twelve round cuvettes supplied |
| Spectrophotometer 400-1000nm | 400–1000 nm | 15 nm bandwidth | Absorbance, transmittance | Round tubes or 10 mm square cuvettes; USB and RS232 |
| Single Beam Spectrophotometer Wavelength Range 325-1100nm | 325–1100 nm | 4 nm spectral bandwidth | Absorbance, transmittance, factor, concentration | Four-position holder for 10 mm cells; 5–100 mm path-length cuvettes |
| Single Spectrophotometer Wavelength Range 190-1100nm | 190–1100 nm | 4 nm spectral bandwidth | Absorbance, transmittance, factor, concentration | Tungsten and deuterium lamps; four-position cell holder |
This model sits between the visible-only 400–1000 nm instrument and the wider-range models: it adds concentration and factor modes, automatic zeroing and a reach down to 335 nm, while keeping the ½″ round-tube format of the 400–1000 nm model. The 325–1100 nm and 190–1100 nm models suit work that needs a narrower bandwidth, long-path cells or, in the second case, the deep ultraviolet.
What Is the Spectrophotometer 335-1000nm Used For?
The instrument selects a narrow band of light with its 1200 lines/mm grating, passes it through the sample and measures the transmitted light with a silicon photodiode. Because absorbance is proportional to concentration (the Beer–Lambert law), the concentration mode can report results directly once the instrument is calibrated with a standard, and the factor mode multiplies absorbance by a known factor to give concentration without a standard curve. Automatic zeroing and one-touch blanking against a reference cuvette reduce set-up time between samples.
Starting at 335 nm, the range includes 340 nm, the wavelength used to follow NADH in many enzyme assays, as well as the visible region used for colorimetric tests. That makes it useful in college and university biochemistry, microbiology, chemistry and environmental labs, for work such as enzyme kinetics, colorimetric estimation of proteins, sugars and ions, and optical density of cultures. Data can be sent over USB or RS232 to a Windows computer, and optional software packages extend the analysis.
What to Specify When Ordering
- Whether the 335–1000 nm range is enough, or your methods need the 325–1100 nm or 190–1100 nm models.
- Whether you want an optional software package for data processing.
- The number of instruments needed for your lab benches.
Frequently Asked Questions
What wavelength range and slit width does it have?
335 to 1000 nm, with a 10 nm slit width. Wavelength accuracy is ± 2 nm and repeatability ± 1 nm.
Which measurement modes are available?
Absorbance, transmittance, factor and concentration, each chosen with the Mode button and shown on the graphic LCD.
Can it measure at 340 nm?
Yes. The range begins at 335 nm, and the stray energy is stated as no more than 0.3% T at 340 nm and at 400 nm.
What sample cells does it accept?
½″ (13 mm) round tubes, or 10 mm square optical glass cuvettes using the square cuvette adapter that comes with it.
What is supplied with the spectrophotometer?
Twelve round optical glass cuvettes, a square cuvette adapter, a dust cover and a user manual.
How does it differ from the Spectrophotometer 400-1000nm?
This model starts lower, at 335 nm, uses a 10 nm slit rather than a 15 nm bandwidth, quotes ± 1% T photometric accuracy, and adds factor and concentration modes with automatic zeroing. The 400–1000 nm model reads absorbance and transmittance only.
What should an export enquiry include?
The number of instruments, any optional software, the destination country and port or city, delivery terms such as FOB or CIF, packing or labelling requirements, and the tender reference if one applies.
Who manufactures the Spectrophotometer 335-1000nm?
JLab — Jain Laboratory Instruments Pvt Ltd — manufactures it in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of laboratory instruments and teaching equipment, incorporated in 2017 and working from Hargolal Road, Ambala, Haryana. This spectrophotometer is produced at JLab’s own works rather than sourced from a trader, so colleges, universities, dealers and importers deal directly with the maker, every unit is visually inspected before it ships, and repeat orders are handled by the same team. JLab exports worldwide and ships to buyers in every region — for example Mexico in North America, Hungary in Eastern Europe, Luxembourg in Western Europe, Costa Rica in Central America and the Caribbean and Kazakhstan in Central Asia. Institutions buying by tender can refer to the JLab lab tenders page.
