4-Channel Independent Control Digital Magnetic Hotplate Stirrer 280°C for Labs
Quick Overview
The MS-H280-S4 is a four-channel LCD digital magnetic hotplate stirrer designed for parallel laboratory experiments. Each position can be controlled independently for starting, stopping, heating and stirring. It supports up to 3 L of water per position, with a speed range of 200-1500 rpm and a heating range of 25-280°C.
Product Description
The MS-H280-S4 integrates four independently controlled heating and stirring positions into one space-saving instrument. Each channel has its own LCD, control knob and operating indicators, allowing users to run four samples with different temperature and speed settings simultaneously.
The ceramic-coated aluminum work plates provide rapid heat transfer and excellent corrosion resistance. PID temperature control ensures stable heating, while the brushless DC motors offer quiet, spark-free and maintenance-free operation.
Each channel can be connected to a PT1000 external temperature sensor for direct sample-temperature monitoring with an accuracy of approximately ±0.2°C. The instrument includes comprehensive safety features such as overheating protection, independent safety circuits and a "HOT" warning when work plates remain above 50°C.
Different heating blocks and reaction-vessel adapters can be installed to support a wide range of parallel experiments.
