Digestion Block

Tuozhiming digestion blocks are designed for efficient and uniform sample preparation in metallurgy, geology, environmental monitoring, agriculture, food testing, chemical analysis, and third-party laboratories. The five-sided surrounding heating structure transfers heat evenly around the digestion vessels, helping reduce uneven digestion and prevent condensate backflow while improving batch-processing efficiency. They combine accurate temperature control, thermal insulation, and corrosion-resistant construction in a practical block digestion system, supporting reliable hot block digestion for multiple sample.

Flexible Block Digestion for Different Laboratory Workflows

Flexible Block Digestion

Customizable Vessel Openings for Diverse Sample Preparation Needs

Our digestion blocks can be configured with customized vessel openings according to the diameter and height of the digestion tubes used in the laboratory. This flexibility allows the equipment to support different sample volumes and batch-processing requirements without limiting users to one fixed vessel format. Our system is suitable for block digestion workflows in metallurgy, geology, chemical analysis, environmental monitoring, agriculture, food testing, research institutions, and third-party laboratories. For laboratories evaluating a TKN digestion block or Kjeldahl digestion block, tube size, required digestion temperature, fume-removal configuration, and compatibility with the validated analytical method should be confirmed before ordering.

Why Choose a Surrounding-Heating Digestion Block?

Surrounding-Heating Digestion Block

Uniform Heat Distribution for Consistent Batch Digestion

Our laboratory digestion blocks use five-sided surrounding heating structure to transfer heat around the digestion vessels, helping reduce temperature differences and support more consistent sample treatment. Compared with simple bottom‑only heating, it eliminates condensate backflow and ensures samples are free from contamination.Accurate PID temperature control, multi-layer thermal insulation, and a corrosion-resistant exterior also help the block digestion system maintain stable operating conditions during acid digestion. For laboratories processing multiple samples, hot block digestion improves batch consistency while reducing the need to monitor each vessel separately. Our split upper and lower structure allows the equipment to perform both digestion and hot-plate heating tasks, making it suitable for laboratories that require flexible sample preparation equipment.
