DuMaster D-480

Unattended and flexible protein determination

DuMaster D-480



The DuMaster D-480 enables unattended and flexible determination of nitrogen or protein according to the Dumas combustion method. The short analysis time of approximately 4 minutes per sample, coupled with the built-in autosampler accommodating up to 120 samples, makes this instrument perfectly suitable for high throughput without supervision.

Your most important benefits: 

Unattended and fast

  • Low costs per sample thanks to:
    • high degree of automation
    • low-priced carbon dioxide as carrier gas as opposed to helium
    • up to 95% savings of oxygen due to automated oxygen control
  • Maximized up times as result of innovative post combustion and Regainer-Reductor technology
  • Highest productivity with 2,000 analyses per one pre-filled reduction tube

Safe and convenient

  • Maximum safety: no contact with harmful chemicals or risk of burns
  • Large sample volume (up to 1 g or 1 mL) analysis thanks to efficient multi-step gas drying
  • Random access of samples at any time (no batch processing required)
  • Remote assistance and troubleshooting over the internet

Voice of the customer

“On-site, rapid and accurate determination of protein has proved invaluable and compliments our NIR detection systems. It has been especially useful for our wet fresh meat samples and QC throughout our meat kitchens and Freshtrusion production facility. I would recommend the equipment.”
