7″ Square Magnetic Stirrer (MS7‑S)

The DLAB 7″ Square Magnetic Stirrer (MS7‑S) is a reliable, economical benchtop instrument engineered for efficient, reproducible mixing in clinical diagnostics, pharmaceutical quality control, microbiology, and general research laboratories. Featuring a large 7‑inch (184×184 mm) square glass ceramic work plate, this stirrer provides a maximum stirring capacity of 10 liters and a stepless speed range of 0 to 1500 rpm, making it ideal for preparing buffers and reagents, dissolving powdered media, and homogenizing samples for a wide variety of diagnostic and research applications.

Every 7″ Square Magnetic Stirrer (MS7‑S) is constructed with a chemical‑resistant glass ceramic work plate that withstands strong acids, strong alkalis, and organic solvents, ensuring long‑term durability and easy cleaning. The robust shaded‑pole AC motor (15 W input, 1.5 W output) provides quiet, vibration‑free operation suitable for continuous daily use. The universal 100–240 V, 50/60 Hz power supply allows direct use in laboratories worldwide without voltage conversion.

Key user‑focused features include stepless analog speed control via a single rotary knob with a clear graduated scale for reproducible speed selection, a large 10‑liter stirring capacity suitable for batch preparation of bulk reagents and quality control materials, and support for stirring bars up to 80 mm in length for powerful magnetic coupling even with viscous solutions. The IP21‑rated powder‑coated metal housing provides protection against solid foreign objects and vertically falling water drops, while the non‑slip rubber feet ensure stability during high‑speed stirring.

For the clinical laboratory scientist, pharmaceutical QC analyst, and water quality technician, the 7″ Square Magnetic Stirrer (MS7‑S) delivers the large‑capacity, chemical‑resistant, and reliable stirring required for routine reagent preparation, buffer mixing, dissolution media preparation, and sample homogenization. For the patient, consistent and accurate mixing of reagents, buffers, and diagnostic samples directly supports reliable test results, safe pharmaceutical products, and effective clinical decision‑making.
