4‑Channel Hotplate Magnetic Stirrer

The DLAB LCD Digital Hotplate Magnetic Stirrer 4‑Channel LCD Digital Hotplate Magnetic Stirrer is a modular, high‑throughput benchtop platform engineered for the true parallel processing of up to four independent heating and stirring reactions in clinical diagnostics, pharmaceutical quality control, analytical chemistry, food and feed analysis, environmental testing, and academic research laboratories.

Featuring four independent ceramic‑coated aluminum work plates (Ø134 mm each), the LCD Digital Hotplate Magnetic Stirrer provides each channel with its own PID temperature control (25–280 °C, 1 °C increments), stirring speed control (200–1500 rpm, ±20 rpm accuracy), and dedicated high‑resolution LCD display for independent real‑time monitoring of temperature and speed. The maximum stirring capacity is 3 litres of water per channel (12 litres total). The PT1000 external temperature sensor ports (±0.2 °C accuracy) enable precise closed‑loop control of the actual sample liquid temperature on each channel.

Key user‑focused features for high‑throughput applications include true independent control of start/stop, temperature, speed, and display for each channel (parallel experiment control); four independent maintenance‑free, spark‑free brushless DC motors for extended life and low‑noise operation; ceramic‑coated aluminum work plates with fast heat transmission and strong corrosion resistance; and ultra‑space‑saving design (701 × 265 × 127 mm, 8.7 kg) with 4 channels integrated into a single instrument—dramatically reducing bench space compared to four separate single‑channel units.

Safety is exemplary with TÜV certification (CE, cTUVus, FCC, CB, UKCA, ICES), dual independent safety circuits providing redundant over‑temperature protection (420 °C hardware cutoff for each channel), an independent residual heat warming indicator (“HOT” flashes on each respective channel display at >50 °C and continues even after the unit is turned off, including unplugged, until each plate is safe to touch), and IP21‑rated housing with an all‑metal aluminium alloy construction for chemical resistance and excellent heat dissipation.

For the clinical laboratory scientist, trace element analyst, pharmaceutical QC chemist, food and feed analyst, and research scientist, the LCD Digital Hotplate Magnetic Stirrer delivers the modular versatility, independent 4‑channel processing capacity, and high safety required for parallel‑batch sample digestion for trace element analysis (blood lead, urine cadmium, heavy metals), multi‑condition dissolution testing, Kjeldahl nitrogen determination, Soxhlet extraction workflows, and multi‑parameter optimisation. For the patient, the reliable and reproducible performance of this high‑throughput instrument ensures that diagnostic tests and pharmaceutical products are accurate and efficient, directly supporting effective clinical decision‑making, appropriate treatment selection, and patient safety.
