BUCHI - Máy phân tích Ni tơ/ Protein thep phương pháp Dumas BUCHI DuMaster D-480
Model: DuMaster D-480
Code: 11060100
Hãng sản xuất: Buchi – Thụy Sỹ
Xuất xứ: Thụy Sỹ
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.
Unattended and fast
· Rapid analysis times of approximately 4 to 6 minutes per sample
· High sample throughput due to fast and automatic autosampler
· Unattended over-night operation of up to 120 samples
· Continuous operation thanks to stable conditions over months
Cost effective
· Automated oxygen control saves up to 95% of oxygen consumption
· Low-price carbon dioxide as carrier gas as opposed to helium
· Low costs per sample thanks to high degree of automation and low consumable costs
Safe and convenient
· No contact with harmful chemicals or burn risks
· 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
