MAVRICA18 single beam UV/Vis spectrophotometer — four models, 190–1100 nm

The MAVRICA18 single beam UV/Vis spectrophotometer series has four models for routine photometry, quantitation, kinetics and spectrum scans. MAVRICA18-U0, U1 and US cover 190–1100 nm with a spectral bandwidth of 2 nm, 1 nm or a selectable 0.5 / 1 / 2 / 4 / 5 nm; MAVRICA18-V0 covers the visible range from 320 to 1100 nm. All models have a 1200 lines/mm grating, a 320×240 LCD with keypad, USB and RS232 output and PC software in standard delivery.

How a single beam UV/Vis spectrophotometer measures

In a single beam UV/Vis spectrophotometer the blank and the sample are measured one after the other in the same light path. The instrument stores the blank and calculates absorbance, transmittance or concentration from the sample reading. With a lamp stability of ±0.0005 A per hour and stray light of 0.05 %T, the MAVRICA18 is a routine UV/Vis spectrophotometer for methods where the blank is repeated regularly — and it costs less than a double beam instrument.

Key characteristics

• Single beam UV/Vis spectrophotometer, holographic blazed grating 1200 lines/mm
• Four models: V0 320–1100 nm, 2 nm · U0 190–1100 nm, 2 nm · U1 190–1100 nm, 1 nm · US 190–1100 nm, 0.5 / 1 / 2 / 4 / 5 nm
• Wavelength accuracy ±0.3 nm (U1, US, V0) or ±0.5 nm (U0); automatic wavelength setting
• Photometric accuracy ±0.3 %T (U1, US) or ±0.5 %T (U0, V0); stray light 0.05 %T; stability ±0.0005 A/h
• Photometry, quantitation, kinetics, multi-wavelength, DNA / protein test and scanning up to 3000 nm/min
• 320×240 LCD with keypad; USB storage, USB and RS232 to a PC, export to Excel; PC software included

Suitable for

• Quality control laboratories with routine UV and Vis methods
• Water and environmental laboratories: nitrate, phosphate, COD and other photometric tests
• Food and beverage laboratories, colour and concentration measurement
• Biochemistry and clinical laboratories: DNA and protein at 260/280 nm, enzyme kinetics
• Teaching laboratories at schools and universities

Why a single beam UV/Vis spectrophotometer

Most photometric methods measure a blank, a few standards and the samples within minutes. A single beam UV/Vis spectrophotometer does this with a simpler optical path and at a lower price, and a fresh blank corrects lamp drift. The four MAVRICA18 models differ only in wavelength range and spectral bandwidth, so the instrument can be chosen for the methods in use: V0 for the visible range, U0 for routine UV/Vis, U1 when 1 nm is required, and US when different methods prescribe different bandwidths.

For long kinetics and scan series without re-zeroing choose a double beam instrument — NOVEL-102S, NOVEL-800 or NOVEL-900; for a 7″ touch screen at 2 nm choose the NOVEL4S — all in the menu above.

Cell holders and sample handling

The large sample compartment of the MAVRICA18 single beam UV/Vis spectrophotometer accepts cuvettes with path lengths from 5 to 100 mm. A manual 4-cell holder for 10 mm cuvettes, 4 glass cuvettes and — with the UV models — 2 quartz cuvettes are in standard delivery; an automatic 8-cell holder, film holder, test-tube rack, Peltier / sipper system and integrating sphere are available as options.

Operation and data

Photometry, quantitation, kinetics, wavelength scan, multi-wavelength measurement and the DNA / protein test are selected from the menu on the 320×240 LCD and started with the keypad. The wavelength is set automatically; the scanning speed is high, medium or low, up to 3000 nm/min.

Test data and working curves are kept in the internal memory. Results are saved to a USB drive or sent to a PC over USB or RS232 and can be exported to Excel; PC software is in standard delivery, 21 CFR compliant software is an option. The deuterium and tungsten lamps sit in sockets and are changed without optical realignment.

Knowledge base

Spectral bandwidth, stray light, Beer–Lambert law and the choice of cuvettes are explained on COLO.Science — UV-Vis spectrophotometry and colour measurement, our knowledge base; how absorbance fits among other laboratory measurements is described in Measurement in laboratory science. The full data are in the MAVRICA18 technical specification (PDF).
