  • PUL-4000N

  • TOP

  • Ultra micro spectrophotometer is an important analytical instrument, which has wide and important applications in scientific research fields such as physics, chemistry, biology, medicine, materials science, environmental science, as well as in modern production and management departments such as chemical engineering, medicine, environmental testing, metallurgy, etc. A spectrophotometer is an instrument that uses spectrophotometry to quantitatively and qualitatively analyze substances, commonly used for nucleic acid, protein quantification, and bacterial growth concentration quantification. Ultra micro UV visible spectrophotometer is commonly used in various fields such as clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbiological testing, food safety testing, molecular biology research, etc.


  • The required sample for detection is low in trace amounts, only 0.5 to 2 uI is needed to complete the detection, with a minimum requirement of only 0.5u. It has dual platforms for ultra trace and colorimetric dishes

  • Wide detection range, 500 times higher than the upper limit of traditional spectrophotometers

  • For most samples, no dilution is required

  • The machine does not require preheating, can measure directly, does not require container inspection, and has low daily consumption

  • Full wavelength range of 190-1100nm with a resolution of 1nm. The instrument automatically provides scanning results for the full wavelength range of 190-900nm

  • Compact size, portable packaging, meeting the needs of on-site testing

  • 2-in-1 function, supporting OD600 detection function, for easy detection of cell, bacterial liquid, and yeast growth density, with comprehensive functions and multiple uses in one machine

  • Built in thermal printer with printing function, capable of storing about 100000 pieces of test data, and can be exported through USB interface, bidding farewell to data loss

  • Intelligent sensing measurement, no need to press any buttons, directly output detection results
