Fully Automated Dumas Nitrogen/Protein Analyser NDA Series
Velp Scientifica presents the NDA Series Dumas Nitrogen/Protein Analyser, consisting in two extremely advanced models aimed to simplify routine operation and reduce operating costs to the minimum. Choose between NDA 701 and NDA 702, a unique dual carrier gas nitrogen and protein analyser.
Both the units use high-technology to optimise productivity. With the highest limits of detection and readability on the market and an RSD lower than 0.5% for EDTA, the user is assured of high precision results. Samples can be loaded in nearly 120 positions, using the same loading procedure whether solid, paste or liquid. Once loaded, the unit runs fully automatically offering exceptional reproducibility and comparability of results. The lowest detection limit of the market ensured, only 0.001 mg/N.
With the new NDA 702 Dual Carrier Gas Dumas N/Protein Analyser, Velp Scientifica takes a further step in enhancing accuracy and end user flexibility. Helium has been the carrier gas for elemental analysis for many years, whilst industry was demanding an alternative carrier gas to address application needs, availability and cost effectiveness. The Velp NDA 702 fulfils the industry’s needs by offering the optimum alternative carrier gas, Argon, which can be utilised seamlessly alongside Helium.
Switching from Helium to Argon or vice-versa with the Velp NDA 702 is truly quick, easy and safe: simply choose the gas, close one tap and open the other. No need to replace parts or upgrade software.
With the Velp NDA 702 absolute flexibility becomes the standard.
No need to decide in advance which carrier gas to use and exciting new features including the completely re-designed DUMASoft™ offering multi- lingual support, results at a glance without the need to create a report, or to name calibration curves. All of this together with the exclusive Velp TEMS™ technology for conspicuous savings in terms of Time, Energy, Money and Space and an unmatched new levels of LOD and accuracy that state an industry record.
Velp Scientifica NDA Series complies with all standards in the food and feed markets – AOAC, AACC, ASBC, OIV and ISO – making it the ideal choice for industrial and monitoring laboratories.

Sample Prep Kit Provides Unparalleled Benefits Compared to Other Commercially Available DNA/RNA Extraction Systems
Cole-Parmer, a leading supplier of laboratory equipment and reagents, is introducing the Arcis Sample Preparation System, which can extract DNA and RNA for downstream processes such as PCR/qPCR and sequencing in just three minutes. A study conducted by the Institute of Infection and Global Health, University of Liverpool, compared the preparation time, DNA yield, PCR and qPCR results of the Arcis Sample Prep Kit with three other kits. The results showed that the Arcis Sample Prep Kit dramatically accelerates pre-analytical sample prep without compromising the quantity and quality of genomic material.
The study showed that competitor preparation kits’ processing times ranged from 20 minutes to 4 hours as they require timely washing, heating and centrifugation steps in order to extract DNA. However, the Arcis Sample Prep Kit required no further instrumentation and was unrivalled as the fastest extraction kit, with a sample processing time of under three minutes. The kit that produced the highest yields was the most
labour-intensive and time consuming, and its high yields were very variable. The Arcis Sample Prep Kit produced either greater or equal DNA yields in comparison to the remaining competitors’ kits, and these yields were obtained in a fraction of the time.
Due to its rapid extraction speed of both DNA and RNA, and overall simplicity, the Arcis Sample Prep Kit will save time and money for labs of all sizes. The Kit can be easily integrated into automated systems, and is also ideal for use with Cole-Parmer’s PCR and qPCR hardware and reagents, such as the pathogen detection kits.
The Arcis Sample Prep Kit is a ready-to-use kit that has the dual capability of extracting both DNA and RNA from a wide range of sample types, requiring as little as 30 µl of whole blood, plasma, urine, bacteria, viruses, and parasites as a starting material. The extraction kit consists of a two-step protocol that is completed in just three minutes, massively simplifying the workflow to provide high quality, PCR-ready templates immediately suitable for downstream molecular investigations.
