A series of heating magnetic stirrers with brushless motors for routine mixing and heating of liquids. Five models cover stirring capacities from 2 L to 20 L and maximum plate temperatures from 260 °C to 550 °C, from a simple knob-controlled unit to digital models with external PT1000 temperature probe and timer.
Key Features
Brushless motor across the entire series for smooth, quiet and long-lasting stirring; counterclockwise stirring
ALAB-HS5 / HS5C / HS5Pro: φ135 mm ceramic-coated stainless steel plate, 2 L maximum stirring capacity
ALAB-HS8Pro: 160 × 160 mm ceramic-coated plate, 5 L capacity, one-click switching between forward and reverse rotation, supplied with bracket and external probe
ALAB-HS550Pro: 184 × 184 mm glass-ceramic plate, upgraded 20 L capacity and 1000 W heating power, designed for high-temperature and large-volume mixing
Maximum plate temperature 260 / 280 / 310 / 550 °C depending on model
Two ways to measure temperature on digital models: built-in plate temperature sensing, or an external liquid probe inserted into the sample to control the liquid temperature directly
Safety setting with over-temperature protection: power is automatically cut off when the safety temperature is exceeded
Three-hole probe clamp holds temperature probes, pH meter probes and other sensors
ALAB-HS5Pro: key control with 1 min-12 h timer, PT1000 temperature measurement and 0.1 °C display
