DK Series Semi-Automatic Digestion Units Versatile, safe and precise aluminium block digesters for Kjeldahl analysis.

Semi-Automatic Digesters The DK Series consists of basic digestion blocks providing accuracy, high thermal homogeneity and minimum energy consumption. The DK Series digesters consist of six models to suit any laboratory need for Kjeldahl digestion, Chemical Oxygen Demand (COD) and Heavy Metals Trace Determinations. Excellent Accuracy and Repeatability ■ Aluminum heating block ensures high thermal homogeneity, heating up to 450 °C ■ 1 °C temperature selection with ± 0.2 °C precision ■ Temperature stability of ± 0.5 °C for consistent performance Versatile and Ready to Use ■ Supplied with tubes...

Kjeldahl Analysis Process Sample Preparation Use genuine consumables designed to provide a solution for digestion, including catalyst tablets and nitrogen-free weighing boats. Place the sample into the Velp Digesters. Choose automatic or semi-automatic models. Hazardous fumes generated during the digestion should be neutralized with the KS 1000 Scrubber. Use the UDK series Velp Distillation Units for the determination of the analytes in your sample. You can now perform the final step. Choose automatic titration with UDK 159-169 or external titration with UDK 149.

The KS 1000 is a compact, tap-water-free scrubber designed to neutralize corrosive and toxic fumes—such as those from Kjeldahl digestion—via a two-stage process: first dissolving gases in a water-based tank, then neutralizing them with sodium hydroxide in a glass tank. It fits neatly under a fume hood alongside Velp’s DKL digesters, and offers an intuitive top-mounted interface with four adjustable suction levels for precise control. Built with durable materials like glass, Viton tubing, and metal/ PVC components—and featuring eight perforated discs for enhanced efficiency—it ensures long-lasting,...
