The World’s First CHNS Macro Elemental Analyzer 
The EMA 402XL combines high-throughput automation, innovative crucible technology, and precise detection to simplify CHNS analysis for complex samples. Its reusable ceramic crucibles allow direct measurement of larger, heterogeneous materials, improving representativity and reproducibility while reducing sample preparation and waste.

The oxidation stability tests performed with the OXITEST reactor accelerate the lipid’s oxidation process that in normal conditions can last weeks or months and provide fast, accurate and reliable results for Food & Feed, Cosmetic, Pharma and Petrochemical industries.

VELP Scientifica’s elemental analyzers are ideal solutions for the determination of carbon and nitrogen in compliance with the combustion method for testing of both solid and liquid samples.

Digesters are widely used instruments in laboratories performing analysis for diversified applications in food and feed, beverage (nitrogen, protein, total Kjeldahl nitrogen), environmental (COD, total Kjeldahl nitrogen, heavy metal trace analysis), chemical and pharmaceutical (Organic nitrogen) industries. DKL digesters work in accordance with a variety of standards, including AOAC, ISO, EPA, DIN etc.

VELP Scientifica offer a range of distillation units that perform nitrogen analysis and protein determination according to the Kjeldahl method used in the food and feed industries. Other applications include environmental and chemical.

VELP Scientifica offers both fully automatic semi-automatic solvent extractors for both solid-liquid extraction processes, as well as fat extraction and sample preparation in a wide range of applications in food, feed, environmental and other industrial segments. VELP Scientifica also offers a convenient, reliable and safe hydrolysis unit for the sample preparation prior to extraction for total fat determination.

VELP Scientifica provides a host of automatic analyzers for crude and detergent fiber, as well as semi-automatic extractors for raw fiber extraction. In addition, the Cold Extractor performs rapid fat extraction on feed samples directly in the FIWE Advance Automatic Fiber Analyzer and FIWE glass crucibles.

The Dietary Fiber Analyzers range of products from VELP Scientifica includes the GDE Enzymatic Digester for dietary fiber analysis by enzymes heating, and the CSF6 Filtration Unit for dietary fiber extraction.

Compact, fully integrated, modular, and scalable laboratory reaction workstation enabling precise control of temperature, pH, reagent dosing, and magnetic or mechanical stirring. Remote control and data logging ensure safe, reproducible, unattended experimentation.

ChemSynt 301 is a compact, modular reaction station designed to perform and control chemical synthesis with precision, safety, and real-time data acquisition.

It features a modular architecture designed for maximum flexibility and scalability. A single leader unit can control up to three additional reaction stations, enabling up to four independent experiments to run in parallel under different conditions.

Each unit operates independently while remaining fully integrated within the system, supporting efficient reaction screening, process development, and optimization.
This scalable approach allows laboratories to increase throughput as requirements evolve, without compromising control, reproducibility, or data quality.

Temperature is one of the most critical parameters in chemical synthesis, influencing reaction performance, selectivity, and reproducibility. ChemSynt 301 combines integrated Peltier cooling and electrical heating to provide precise temperature control from -30 °C to +150 °C, extendable to -40 °C with an external chiller.

Programmable temperature profiles and continuous monitoring of both Reaction Temperature (Tr) and Jacket Temperature (Tj) ensure accurate reaction management and reliable data collection throughout the experiment.

• Temperature range from -30 °C to +150 °C (-40 °C with external chiller)
• Integrated heating and cooling in a single platform
• Programmable temperature profiles and ramps
• Real-time monitoring of Tr and Tj with continuous data logging

Efficient stirring is essential for heat and mass transfer and for reaction reproducibility. ChemSynt 301 supports both magnetic and mechanical stirring, allowing users to select the most suitable mixing strategy for different process requirements.

Three PTFE impeller geometries help replicate industrial mixing conditions, while the compact overhead stirrer ensures easy installation and reliable operation.

• Magnetic and mechanical stirring in a single platform
• Three PTFE impeller configurations for process development and scale-up
• Improved mixing, heat transfer, and solid suspension
• Compact overhead stirrer with quick screw-lock coupling

Accurate reagent addition is essential for reaction control  and high selectivity. ChemSynt 301 can be equipped with a single or double DU50 Dosing Unit, providing precise and flexible reagent dosing throughout the synthesis process.

Continuous dosing with automatic syringe refilling enables uninterrupted operation during long experiments, while reducing manual intervention and improving process consistency. The result is more reliable data and greater confidence in process optimization and scale-up activities.

• Single or double DU50 configuration for maximum flexibility
• Continuous dosing with automatic syringe refilling
• Reduced operator intervention and improved process consistency
• Reliable support for process optimization and scale-up studies

pH is a critical parameter in chemical synthesis, affecting reaction pathways, selectivity, and final product quality. ChemSynt 301 continuously monitors pH and allows users to define target setpoints for different reaction stages.

When paired with the optional DU50 Dosing Unit, the system automatically adds acids or bases to maintain the desired pH, ensuring consistent and reproducible reaction conditions.

• Continuous pH monitoring with real-time data logging
• User-defined pH setpoints for automated control
• Automatic acid/base dosing with the optional DU50
• Improved process understanding and reproducibility

ChemSynt 301 features intuitive control through both ControlPad and PC software, enabling simple setup and efficient operation.

The integrated data logger continuously records key parameters such as temperature and pH at a frequency of one data point per second, generating a complete dataset for every experiment.

Data can be monitored locally or remotely, providing real-time visibility of reaction progress and supporting informed process optimization and decision-making.
