LSP-1004 / LSP-1102 series are entry-level single-beam spectrophotometers with dot matrix LCD, including visible light version (V) and UV-visible version (UV), with two spectral bandwidth options: 4.0nm and 2.0nm. They target basic teaching labs of colleges, routine industrial QC of small factories, grassroots environmental monitoring stations and testing rooms of small chemical/food enterprises for student trainees, basic lab technicians and low-budget daily QC operators. It solves pain points of old simple spectrophotometers such as limited storage capacity, lack of automatic wavelength calibration, non-intelligent light source switching, no power-off data protection, poor compatibility of optional accessories and difficulty in purchasing storage-enabled instruments with tight budgets.

Adopting single-beam optical system with 1200 lines/mm grating, the series provides 4.0nm wide bandwidth (1004 series) and 2.0nm standard bandwidth (1102 series). Light source options include pure tungsten lamp for visible range, and tungsten + deuterium dual lamp for full UV-Vis range with intelligent automatic switching to extend lamp service life. Equipped with dot matrix LCD, the unit supports local storage of 128 calibration curves and 4000 test data sets, with real-time data saving to avoid loss during sudden power failure. It integrates six basic analysis modes: photometric measurement, quantitative assay, kinetics scanning, spectrum scan, basic DNA/protein quantification and multi-wavelength test. Dual output ports (USB & parallel) support connection with printers and PC software, alongside automatic wavelength calibration and dark current correction. Standard configuration includes 1cm manual 4-position sample holder, fully compatible with auto cell holder, thermostatic autosampler, micro cell mount, reflection accessory, integrating sphere and other expandable accessories. Compact and lightweight (11kg / 14.6kg, dimension 475×360×225mm), it features ultra-low procurement cost, ideal for entry-level labs with tight budgets only undertaking routine batch screening and basic teaching training

Dual bandwidth & dual spectrum versions available: 4.0nm economical wide bandwidth (LSP-1004), 2.0nm standard universal bandwidth (LSP-1102); two light source configurations (visible only / full UV-Vis) to cover pure visible and full-spectrum testing demands, flexibly matching budget and precision requirements.
Japan imported tungsten / deuterium-tungsten combined light source: Original HYBEC tungsten lamp, Milaras deuterium lamp with intelligent automatic switching and idle lamp power-off to greatly extend lamp service life and cut consumable replacement cost.
Dot matrix LCD simple interactive screen: Intuitive interface allows untrained students and grassroots technicians to operate quickly, with low failure rate and easy maintenance.
Large-capacity local storage: Stores up to 128 calibration curves and 4000 test data sets with real-time auto-save to prevent data loss during sudden power outage.
Fully automatic calibration functions: Built-in auto wavelength calibration and dark current correction programs eliminate manual baseline adjustment and reduce human operation error.
Intelligent light source energy-saving system: The instrument automatically switches the corresponding lamp according to test wavelength and powers off idle lamps to effectively extend deuterium & tungsten lamp lifespan.
Six integrated basic analysis programs: Photometry, quantitation, kinetics, spectrum scanning, basic DNA/protein test and multi-wavelength analysis, covering all basic experiments for teaching training and routine production batch screening.
Series universal optional accessories: Fully compatible with auto cell holder, thermostatic autosampler, adjustable micro cell mount, reflection accessory, integrating sphere and more, sharing consumables with full spectrophotometer series with no full accessory replacement needed for later upgrade.
Dual output ports (USB + Parallel): Direct connection with printers for test report printing, or matched PC software for extended functions including wavelength scan, kinetics, multi-wavelength and DNA/protein analysis.
Compact lightweight body: Dimension 475×360×225mm, net weight only 11kg / 14.6kg, occupying minimal lab bench space and easy to transport & place, perfect for small testing rooms and classroom workbenches.

What are core differences between LSP-1004 and LSP-1102 series?
①Spectral bandwidth: 1004 series standard 4.0nm; 1102 series narrow high-resolution 2.0nm with overall superior wavelength accuracy, repeatability, stray light and photometric stability, outstanding for trace low-concentration samples.
②Wavelength coverage: V visible models 1004:325–1000nm, 1102:320–1100nm; UV dual-light models 1004 cut-off 200nm, 1102 extends down to 190nm for wider short-wave UV range.
③Photometric error: The 1102 series delivers better absorbance & transmittance precision and repeatability.
④Stray light: 1102-V ≤0.05%T vs 1004-V ≤0.2%T, lower stray light reduces background interference for trace specimens.
⑤Positioning: 1004 for basic teaching & routine standard testing; 1102 for R&D, trace nucleic acid and high-precision drug gradient trials.
What do suffix V and UV stand for in light source, how to select?
-V: Only Japan HYBEC tungsten lamp, visible band starting at 325/320nm, for colored substance & visible protein quantification without UV measurement demand.
-UV: Dual tungsten + Milaras deuterium lamp covering full UV-NIR from 190/200nm; mandatory selection for DNA/RNA nucleic acid, UV-absorbing drug and organic solvent testing.
How many standard curves and test data can be stored, will data be lost after power cut?
Up to 128 complete standard curves and 4000 raw test records; all data & curves are auto-saved in real time during power failure, files can be recalled directly after power recovery without re-calibration or re-test.
Does the instrument support automatic wavelength calibration, is manual baseline correction required?
Built-in auto wavelength & dark current calibration program; one-touch baseline zeroing by loading blank reference before each run, no manual wavelength adjustment needed.
Can light sources switch automatically to extend bulb service life?
UV dual-light models auto-switch tungsten / deuterium lamp according to set wavelength and turn off idle lamp outside corresponding band to drastically reduce bulb wear and extend lifespan; single V tungsten lamp model has no switching logic.
What optional extended accessories are available for special sample testing?
Optional attachments: auto temperature-controlled cell holder, 8-strip / 96-well plate tube rack, solid reflectance sample holder, variable long optical path components, thin film rack for temperature-controlled kinetics, solid powder and high-throughput microplate workflows.

Does the wide voltage fit overseas 110V labs?
Auto-adaptive wide voltage 110/220V 50/60Hz, European, American and Southeast Asian overseas labs can operate directly without external voltage transformer.
Power consumption and net weight difference between single V lamp and dual UV lamp versions?
Single tungsten V model: 80W power, 11kg net weight; dual tungsten-deuterium UV model: 120W power, 14.6kg net weight; all four models share identical overall dimension 475×360×225mm.
Is the stray light gap obvious between two series, what impact on trace samples?
1004 series stray light ≤0.2%T@360nm; 1102 series ≤0.05%T (UV models controlled at both 220nm & 360nm). Lower stray light minimizes background interference of low-concentration trace samples and improves quantitative accuracy.
Does it support kinetics and Touchdown gradient wavelength scan experiments?
