product key technologies

When it comes to determining protein content in samples, one of the biggest challenges for lab workers is the time-consuming digestion and boiling process. That's exactly why this digital display digestion furnace was designed - to speed up these steps significantly, while still delivering consistent, reliable results that you can trust. It has a simple, clean look and is lightweight enough to move around the lab easily, so it won't take up too much space or be a hassle to integrate into your daily workflow. Even if you're new to using this kind of equipment, you'll find it straightforward to operate, with no complicated setup required.
To speed up protein content determination, this digital display digestion furnace is designed to shorten sample digestion and boiling time, while ensuring reliable results. It has a simple, lightweight design that's easy to operate and fits seamlessly into daily lab workflows, even for less experienced users.
Its core heating element uses infrared quartz tubes, which are resistant to strong acids and alkalis, anti-burst, and durable for long-term use. The furnace provides a large, evenly heated area for digestion tubes with minimal temperature difference, ensuring consistent sample digestion, high thermal efficiency, and complete sample breakdown - key for accurate testing.
Equipped with a new digital display temperature controller, it enables precise temperature regulation and fast heating to suit different digestion needs. For lab safety, harmful gases like SO₂ from digestion tubes are safely discharged into the sewer via a sewage collection pipe and water-connected suction filter pump, protecting lab staff.
A full batch of samples takes just 60–90 minutes to digest (varies by nitrogen content), greatly reducing the overall protein testing cycle. Practical, safe, and efficient, it's an essential tool for labs conducting routine protein and nitrogen analysis.

Working Principle
Under the action of intense heating, a catalyst and concentrated H2SO4, the ammonium group in organic compounds undergoes nitration to form (NH4)2SO4. The reaction equation is: 2NH2- + H2SO4 + 2H+ = (NH4)2SO4
