20L LCD Digital Hotplate Magnetic Stirrer Stainless Steel Plate with Timer, 340℃
Product Overview
The MS-H-ProT is an LCD digital magnetic hotplate stirrer with timer, designed for controlled laboratory heating and mixing. It offers a maximum stirring capacity of 20 L, speed range of 100-1500 rpm and heating from room temperature to 340°C. Its Ø135 mm ceramic-coated stainless steel work plate provides excellent chemical resistance and efficient heat transfer.
Key Features
- Combines digital heating, magnetic stirring and timed operation in a compact benchtop unit
- LCD displays actual speed, temperature and operating time for convenient process monitoring
- Timer range: 1 minute to 99 hours and 59 minutes
- Heating stops while stirring continues when timer ends, protecting temperature-sensitive samples
- Brushless DC motor provides stable, low-noise operation with minimal maintenance
- PT1000 sensor enables liquid temperature control with accuracy of approximately ±0.2°C
- Overheating protection and "HOT" warning flashes when work plate temperature exceeds 50°C
- RS232 interface supports computer connection for remote control and data transmission
Applications
- Timed heating and mixing of liquid samples
- Preparation of laboratory solutions and reagents
- Dissolving powders and chemical compounds
- Buffer and culture-media preparation
- Chemical synthesis and reaction experiments
