iStir HP 15M Fifteen-Position Hotplate Stirrer

The iStir HP 15M is a high-capacity multi-position hotplate stirrer designed for laboratories that need to heat and mix large numbers of samples under consistent operating conditions.

Fifteen stirring positions each accommodate up to 400 ml, providing a combined maximum capacity of 6 litres. All positions operate synchronously, helping ensure that each sample receives the same stirring speed, temperature and processing time.

A maintenance-free brushless DC motor, digital control, programmable pulse mixing and uniform heating make the iStir HP 15M an excellent solution for high-throughput research, quality-control and sample-preparation workflows.

• Closed, spill-resistant housing helps protect the internal components
• IP42-rated construction for dependable routine laboratory operation

The fifteen-position working surface enables complete batches of samples to be processed together. All positions use the same speed, temperature and timer settings, helping reduce variability between vessels.

This makes the instrument particularly useful for repetitive sample preparation, comparative experiments, formulation work and laboratory procedures where multiple samples must be treated under identical conditions.

The stainless-steel heating surface is designed to provide homogeneous temperature distribution across the complete working area. Heating can be adjusted from ambient temperature up to 120°C.

A silicone anti-slip sheet helps secure vessels during operation, while the waterproof heater incorporates an integrated safety cut-off for added protection.

Pulse mode periodically changes the stirring direction to promote improved liquid circulation and more thorough mixing. The pulse interval can be programmed between 30 and 99 seconds to suit different samples and procedures.
