Visible spectrophotometer, 325-1000nm, 5nm

VSP-722SP visible spectrophotometer, 325-1000nm, 5nm

Product Introduction

VSP-722SP visible spectrophotometer has the characteristics of high quality, complete functions, light weight and novelty. As the newest product in this series, VSP-722SP visible spectrophotometer combines the advantages of VSP-722S and VSP-S22PC,  is the preferred detection tool in manufacturing, inspection, monitoring and college teaching laboratories.

Instrument features

• Unique independent external filter can reduce more stray light.
• It has single-machine sample concentration direct reading and concentration factor functions.
• The working band range is extended to 325-1000nm, and the wavelength is adjusted manually.
• The photometric repeatability index is increased to 0.2%τ, and the test reliability is more guaranteed.
• The stray light index is the same as that of our company's VSP-S22PC, and the value is below 0.2%τ. This index is especially important for users who use extreme wavelengths and measure high absorbance values.
• The spectral bandwidth is 5nm, which can meet various test requirements.
• It has 4 test modes: transmittance τ, absorbance A, concentration direct reading C and concentration factor setting F, which can be switched arbitrarily according to user requirements.
• Reasonable structure and advanced optical system design, using precision-machined high-quality C-T monochromator and sealed grating, small size, good optical performance
• Special precision pre-adjusted lamp and lamp holder, no need to adjust the light path again can be replaced and installed by yourself, providing convenience for users who do not have professional maintenance skills
• Precision linkage cut-off filter system can automatically switch to the corresponding filter according to the wavelength to further reduce stray light
• The sample chamber is made of special engineering plastics resistant to solvents and strong acids and alkalis, fully anti-corrosion, and a removable liquid accumulation tray and liquid storage container are installed at the bottom to improve the quality of the instrument user end, It is the best solution to solve the problem of shortened instrument life due to bad test conditions.
• 4-cell, 10-50mm cuvette can be used.
• The instrument has 2 interfaces: RS232C for software connection and print port for micro printer connection.
• The flame-retardant and insulated all-plastic shell is safe to use, light in weight and easy to transport and move.
• The power supply range allowed by the instrument is extended to 100-240V.
• The manufacturing process is standardized, universal and consistent, with full mold production technology and a large number of standard tooling equipment. ISO9001/2000 system certification ensures that product quality is fully controlled and instrument quality is guaranteed.
