Buffer Preparation

The  LCD Digital Enhanced Magnetic Hotplate Stirrer (with Timer) is a premium, TÜV‑certified benchtop instrument engineered for accurate, safe, and consistent simultaneous heating and stirring – especially in challenging applications involving viscous liquids – in pharmaceutical bioprocessing, clinical diagnostics, and industrial research. Featuring a 5‑inch (φ135 mm) ceramic‑coated aluminum work plate, this enhanced hotplate stirrer delivers a heating range of room temperature to 340 °C (±1 °C accuracy in 1 °C increments) and a stirring speed range of 100 to 1500 rpm (±1 rpm accuracy) with a maximum stirring capacity of 20 litres of water.

Every LCD Digital Enhanced Magnetic Hotplate Stirrer is individually factory‑calibrated and supplied with a calibration certificate traceable to international standards. The high‑resolution LCD display simultaneously shows set and actual values for temperature, speed, and timer, providing complete operational visibility at a glance. The ceramic‑coated aluminum work plate resists strong acids, strong alkalis, and organic solvents, providing rapid, uniform heating without localised hot spots. Crucially, enhanced magnets and a high‑torque brushless DC motor guarantee outstanding stirring performance even with highly viscous liquids (e.g., 50 % glycerol, polymer melts), preventing stir bar decoupling and ensuring smooth, stable mixing.

Key user‑focused features for industrial and clinical workflows include three selectable heating modes (fast, standard, and steady) for optimal thermal control; a fully integrated programmable timer (1 min to 99 h 59 min) for fully unattended automated operation – with automatic heating shut‑off while continuing stirring to protect heat‑sensitive samples; an optional PT1000 external temperature sensor (±0.2 °C accuracy) for precise regulation of the actual sample liquid temperature; an RS232 remote control and data‑logging interface for GLP‑compliant experiment documentation; and the ability to run the instrument as a combined heating/stirring unit, a stirring‑only unit, or a heating‑only unit.

Safety is exemplary with TÜV certification (CE, cTUVus, FCC), dual independent safety circuits providing redundant over‑temperature protection (420 °C hardware cutoff), automatic short‑circuit power shut‑off via a second independent safety circuit, an independent residual heat warning indicator (“HOT” flashes on the display at >50 °C and continues even after the unit is turned off, including unplugged, until the plate is safe to touch), and IP21‑rated housing offering basic splash and dust protection. Smooth‑start technology and controlled deceleration of the enhanced magnetic drive minimize splashing and sample loss, even with heavy stir bars.

With a compact footprint (280 × 160 mm) and moderate weight (2.8 kg), the MS‑H‑ProM occupies minimal bench space while delivering high‑performance suitable for demanding industrial and clinical workflows. The instrument is backed by a 2‑year manufacturer’s warranty and is supported by a global distributor network.

For the pharmaceutical bioprocess scientist, industrial chemist, clinical laboratory technician, and trace element analyst, the LCD Digital Enhanced Magnetic Hotplate Stirrer delivers the high‑throughput versatility (20‑litre stirring capacity), high‑temperature performance (340 °C), advanced timer automation, and true regulatory‑grade safety required for sample digestion for trace element analysis (heavy metals, blood lead, urine cadmium), high‑viscosity formulation development, quality‑control sample preparation, and general‑purpose heating and mixing. For the patient, the reliable performance of this advanced, TÜV‑certified instrument ensures that diagnostic tests and pharmaceutical products are accurate, reproducible, and processed efficiently, directly supporting effective clinical decision‑making, appropriate treatment selection, and patient safety.
