iStir HP 5M Five-Position Hotplate Stirrer

The iStir HP 5M is a digitally controlled multi-position hotplate stirrer designed to heat and mix up to five laboratory samples simultaneously.

Each position can accommodate up to 400 ml, providing a combined maximum stirring capacity of 2 litres. Synchronous operation maintains consistent stirring conditions across all five positions, making the instrument ideal for parallel sample preparation and comparative procedures.

A maintenance-free brushless DC motor, programmable pulse mode and digital control of speed, temperature and operating time provide dependable and repeatable performance for research, quality-control and routine laboratory workflows.

• Digital display provides clear viewing of the operating parameters
• Timer from 1 to 999 minutes with an additional continuous operating mode
• Programmable pulse mode with adjustable intervals from 30 to 99 seconds
• Brushless DC motor provides quiet, consistent and maintenance-free operation
• Microprocessor-controlled performance maintains reliable operation under changing loads
• Waterproof heater with an integrated safety cut-off
• Stainless-steel heating plate with a silicone sheet for vessel stability
• Closed, spill-resistant construction simplifies cleaning and protects internal components
• Non-slip rubber feet provide stability during higher-speed operation

The five stirring positions operate synchronously, allowing multiple samples to be processed under the same speed, temperature and time settings.

This helps improve consistency between samples and reduces the amount of equipment and bench space required for batch preparation, comparative testing and repetitive laboratory procedures.

The stainless-steel working plate provides homogeneous temperature distribution across the five positions. Temperature can be set from ambient conditions up to 120°C, allowing samples to be mixed with controlled heating.

A silicone anti-slip sheet helps keep vessels stable and protects the working surface during routine use. The waterproof heating system incorporates a safety cut-off for additional operational 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 the sample and procedure.
