Product Overview
This is a high-quality digestion tube specifically designed for Kjeldahl nitrogen analyzers, with dimensions of 45mm (outer diameter) × 260mm (length) and a bowl-shaped tube opening. It is made of 3.3 borosilicate glass, which can withstand temperatures above 300℃, is corrosion-resistant, has uniform wall thickness and high transparency, ensuring safety and reliability in experiments.
Key Features
Material Advantage: 3.3 borosilicate glass resists corrosion from strong acids used in digestion processes, preventing contamination during nitrogen determination and maintaining the accuracy of test results. Optimized Design: The bowl-shaped opening facilitates sample loading and prevents spillage, while the 45mm×260mm dimension ensures sufficient space for sample digestion, even for samples that foam severely during the process.
Applications
Widely used in food, feed, pharmaceutical, environmental monitoring, and agricultural product testing fields for protein content determination. Suitable for digesting samples with high nitrogen content, such as water samples (up to 500ml can be processed at once), solid samples, and samples requiring incremental concentration digestion. Can be used for direct distillation of solid samples with catalysts (Devarda’s alloy, magnesium powder, chromium powder, etc.) to measure volatile basic nitrogen, nitrate nitrogen, etc.
