Q1: What types of samples are suitable for processing on the ceramic heating surface?
A: The glass‑ceramics panel is heat‑ and corrosion‑resistant, ideal for digestion, boiling, or acid vapor treatment of strong acid/alkali samples (e.g., soil, water, food pretreatment). Avoid using with hydrofluoric acid or molten samples.
Q2: What are the advantages of the split‑type design?
A: The separate controller keeps the operator away from acid fumes and hot vapors generated during heating, improving safety. Especially suitable for long‑term, high‑throughput sample processing.
Q3: What features does the temperature control system offer?
A: It uses a PID microprocessor system that combines fixed‑value control and multi‑segment programmable control, with functions such as scheduled start/stop, timer, AT self‑tuning, and power‑off memory.
Q4: How is heating uniformity ensured?
A: The large‑area panel provides uniform heating with ±1°C fluctuation, ensuring consistent heating for batch samples. For best results, distribute containers evenly and avoid stacking.
Q5: What safety protections are included?
A: Over‑temperature audio‑visual alarm, independent temperature limit, and dry‑burn protection. Recommended to operate inside a fume hood and wear protective gear when handling corrosive samples.
Q6: How to choose between power and size options?
A: DW‑12F (2 kW, 300×400 mm) is suitable for small‑ to medium‑throughput; DW‑24F (3 kW, 400×600 mm) is better for high‑throughput or larger containers. Both require 220 V/50 Hz power.
Q7: How to clean and maintain daily?
A: Wait until the panel cools completely, then wipe with a damp cloth or mild detergent. Avoid scratching the surface with sharp objects. For stubborn residues, diluted acid can be used after prolonged use.
Q8: Which industries and applications is it designed for?
A: Widely used in environmental protection, hydrology, agricultural product testing, research institutes, etc., for sample digestion, boiling, acid evaporation, constant‑temperature baking, and reagent heating.
Q9: Does it support programmable temperature ramping?
A: Yes, multi‑segment programming allows setting different temperature stages and hold times, suitable for complex digestion procedures requiring step‑wise heating.
Q10: How to ensure experimental consistency?
A: Use the multi‑segment program to standardize heating profiles for all samples and employ the timer function to control processing duration. It is recommended to use containers with consistent heat resistance and avoid frequent on/off cycling.
