UPT-XH20 Intelligent Constant-Temperature Digestion Block

Product Introduction
The UPT-XH20 Intelligent Constant-Temperature Digestion Block is a laboratory sample preparation instrument designed for chemical analysis of soil, feed, plants, seeds, ores, and other materials. It is widely used in food testing, pharmaceuticals, agriculture, forestry, environmental monitoring, chemical analysis, biotechnology, universities, and research laboratories.
With a 20-position heating block, the UPT-XH20 can digest up to 20 samples simultaneously, improving laboratory throughput and processing consistency. Its intelligent PID temperature control system provides stable, uniform heating up to 450°C, while advanced insulation and corrosion-resistant surface treatment enhance operational safety and durability.
The instrument is also suitable as a sample pretreatment unit for Kjeldahl nitrogen analysis.

Performance Features
• 20-sample capacity: Processes up to 20 samples simultaneously to improve laboratory efficiency.
• Intelligent PID temperature control: Provides precise, stable temperature regulation with a specified accuracy of ±1°C.
• Fast heating: Heats from room temperature to 400°C in approximately 25 minutes.
• Uniform heat distribution: Three-dimensional surrounding heating helps distribute heat evenly across the samples.
• Advanced thermal insulation: Reduces external housing temperature rise and improves operating safety.
• Corrosion-resistant design: Specially treated upper surfaces, work surfaces, and tube racks provide resistance to acidic and alkaline environments.
• Enhanced heating-block durability: Anti-oxidation treatment helps extend heating-block service life.
• Intelligent fault monitoring: Monitors heating elements and provides automatic alarms when abnormalities are detected.
• Multiple protection functions: Includes overvoltage, overcurrent, and overtemperature protection.
• Optional touchscreen control: A high-end color touchscreen can provide an enhanced human-machine interface and timed operation with automatic shutdown.
• Optional programmable heating: Up to 30 heating-program stages can be configured for different digestion procedures.

Working Principle
The UPT-XH20 uses controlled block heating to digest laboratory samples before chemical analysis.
1. Sample preparation: Samples and suitable digestion reagents are placed in compatible digestion tubes.
2. Positioning: The tubes are placed into the 20-position heating block.
3. Controlled heating: The intelligent PID controller regulates the heating elements to reach and maintain the selected temperature.
4. Uniform digestion: The surrounding heating structure promotes consistent heat transfer among sample positions, supporting reproducible digestion.
5. Safety monitoring: The system monitors heating-element status and incorporates electrical and temperature protection functions.
After digestion and appropriate cooling, the prepared samples can be used for subsequent analytical procedures, including Kjeldahl nitrogen determination where applicable.
