Precision Kjeldahl Digestion for Laboratory Analysis

Designed to simplify nitrogen and protein determination by the Kjeldahl method, this digestion unit supports accurate and efficient multi-sample processing. With heating block choices in aluminium alloy or mild steel and advanced insulation, users benefit from rapid temperature ramp-up and uniform heat distribution. Its compatibility with standard 300 ml tubes and multiple capacity options make it adaptable to varied laboratory workloads.

Safety and Efficiency Built In

Safety is prioritized with integrated over-temperature protection, an acid splash shield, and ceramic wool insulation for reduced energy loss. The analog control panel, temperature indicators, and acid-resistant design offer user-friendly operation and durability even under rigorous laboratory conditions. Optional cooling trays and semi-automatic controls provide increased flexibility and sample throughput.

FAQs of Kjeldahl Digestion Units:

Q: How does the Kjeldahl Digestion Unit ensure precise temperature control during operation?

A: The unit utilizes high-precision analog temperature control and energy-efficient ceramic heating elements, ensuring uniform heat distribution up to 450C. Indicator lights provide real-time status, while a built-in thermostat maintains set temperatures consistently.

Q: What types of samples can be processed with this digestion unit?

A: This system is suitable for batch processing sample sizes ranging from 0.25 g to 3 g, making it ideal for food, environmental, agricultural, and chemical laboratory analyses requiring nitrogen or protein determination.

Q: When is a cooling tray necessary, and is it included with the equipment?

A: A cooling tray becomes essential when rapid sample cooling is needed after digestion, reducing handling time and improving safety. It is offered as an optional accessory and can be requested based on laboratory requirements.

Q: Where should the fume duct connection be installed for optimal safety?

A: The standard exhaust outlet should be connected to a laboratory-grade fume extraction system. Proper installation ensures effective removal of hazardous vapors and acids, safeguarding laboratory personnel during operation.

Q: What steps are involved in the Kjeldahl digestion process using this unit?

A: Begin by placing weighed samples into the compatible 300 ml digestion tubes, add reagents as per protocol, and set the required temperature using the control panel. After digesting for the specified time, samples are cooled, typically with the optional tray, before proceeding with subsequent analysis steps.

Q: Can the unit handle multiple samples simultaneously, and how does this improve efficiency?

A: Yes, models are available for 6, 12, or 20 samples, enabling batch processing. This capability accelerates laboratory workflow, enhances throughput, and is particularly beneficial for high-volume analytical environments.
