JP Selecta UV-VIS Spectrophotometers
JP Selecta laboratory spectrophotometers measure the absorbance and transmittance of liquid and solid samples across a 190-1,100 nm range (full UV-VIS), applying the Beer-Lambert law to quantify proteins, nucleic acids, metal ions, active pharmaceutical ingredients and dyes.
Alongside spectrophotometers we also offer precision analytical instruments —conductivity meters, pH meters and colorimeters— covering the complete physico-chemical analysis of the laboratory.
At JP Selecta we manufacture everything needed to equip your laboratory under demanding quality standards and full regulatory compliance (European Pharmacopoeia, USP <857> and <1857>, NIST SRM 2034 traceability and ASTM E275).
JP Selecta spectrophotometer catalogue
Our analytical instrumentation range is organised into specialist tiers to precisely match different resolution, automation and sample-volume needs across teaching, clinical or research settings.
Dual-beam UV-VIS spectrophotometers (190-1,100 nm)
UV-6301 flagship: designed for demanding analytical work, this unit incorporates a fully stable dual-beam optical system with a narrow 1 nm spectral bandwidth.
Built-in methods: advanced photometry, kinetics with real-time graph visualisation, standard curves for up to 10 solutions, and DNA/protein purity and concentration analysis natively, without external software.
Secure data handling: automatic wavelength calibration and an optimised USB output to dump records directly to external flash storage.
Single-beam UV-VIS spectrophotometers (190-1,100 nm)
UV-2005 and UV-3100 models: flexible units with automatic wavelength selection, automatic blank and 2 nm spectral bandwidth. They reduce stray light to just 0.05% T and allow full PC control through Windows®-based software.
UV-2005 logging capacity: 128 × 64 bit LCD screen and built-in RAM to store up to 200 data groups and 200 calibration curves.
UV-3100 advanced versatility: designed for multicomponent analysis, spectrum scanning at various speeds, kinetic reaction-rate calculation, and nucleic acid purity determination through 260/280 nm or 260/230 nm absorbance ratios.
Microvolume with Nano-Drop Digital 7: latest-generation spectrophotometer with Android system and touchscreen, able to measure samples of just 0.5 µl to 2 µl with no dilution required. Operates in a 200-800 nm range, integrates a thermal printer and features a dedicated 600 nm (OD600) function for rapid bacterial cell-growth determination.
Visible-range spectrophotometers (320-1,100 nm)
V-1100 manual model: single-beam unit with manual wavelength selection. Its ergonomic, robust and simplified design makes it the ideal tool for laboratory technicians and teaching centres.
VR-2000 automatic model: automatic wavelength selection and an LCD screen that simultaneously displays standard curves and their regression equations. Its RAM stores 50 data groups and 10 curves.
Common quality optics: both models include a high-quality silicon photodiode detector, a 1,200 lines/mm diffraction grating and a sample compartment suitable for standard 10 mm cuvettes or optional path lengths up to 100 mm.
Complementary precision analytical instruments
Clormic digital colorimeter: microprocessor-controlled unit with a 400-800 nm spectral range that uses a 12-position disc for manual selection of interferential filters.
Photometer S-2000 clinical analyser: semi-automatic analyser with 47 pre-programmed biochemistry techniques (cholesterol, glucose, urea, etc.), memory for 130 techniques and a Peltier-thermostatted cuvette holder adjustable to 25, 30 and 37 °C.
Combine with JP Selecta viscometers for full analytical characterisation of liquid formulations.

Frequently asked questions
What is a spectrophotometer and what is it used for in the laboratory?
A spectrophotometer is an instrument that measures the light absorbed or transmitted by a sample at a given wavelength. It is used to determine substance concentrations, analyse proteins and nucleic acids, perform enzyme kinetics and carry out quality control in chemical, pharmaceutical and clinical laboratories.
What is the difference between a single-beam and a dual-beam spectrophotometer?
A single-beam spectrophotometer measures the blank first and then the sample. A dual-beam model analyses both simultaneously, offering higher stability and accuracy in extended measurements.
Which regulations do JP Selecta spectrophotometers comply with for pharmaceutical use?
JP Selecta spectrophotometers deliver high optical performance and meet the validation requirements of the European Pharmacopoeia and USP (chapters <857> and <1857>), making them suitable for pharmaceutical analysis and quality control.
How is a laboratory spectrophotometer calibrated and verified?
Most units incorporate self-diagnostic and automatic wavelength calibration functions. Their performance can also be verified with certified reference materials (for example NIST SRM 2034) to guarantee measurement accuracy.
What is the difference between a UV-VIS spectrophotometer and a colorimeter?
A UV-VIS spectrophotometer works across the ultraviolet and visible range, allowing high-precision analysis of a wide range of compounds. A colorimeter, by contrast, only measures within the visible range through filters, making it better suited to specific colorimetric analyses.
What is a laboratory conductivity meter used for and how does it relate to spectrophotometry?
A conductivity meter measures the electrical conductivity of a solution to determine the amount of dissolved salts and ions. Spectrophotometry, on the other hand, identifies and quantifies specific compounds through light absorption, so both techniques are complementary.
Can I use a JP Selecta spectrophotometer for water and food analysis?
Yes. They are standard tools in agri-food and environmental control. They monitor colorimetric assays, quantify dye and chemical residue concentrations and determine bacterial growth in culture solutions by measuring optical density at 600 nm (OD600).
