The Labmart LMMS300 Hotplate Magnetic Stirrer is a microprocessor-controlled laboratory heating and stirring system designed for simultaneous sample heating and magnetic stirring. It provides a maximum plate-surface temperature of 300°C, stirring speed up to 1250 RPM, and a maximum volume of 2000 mL.

The LMMS300 features an LCD display, digital speed control, programmable temperature and stirring parameters, 999-minute timer and automatic temperature control using an ATC temperature probe. Its 135 × 135 mm stainless-steel top plate provides a durable laboratory heating surface.

3. Detailed Product Description

Product Overview

The Labmart LMMS300 Hotplate Magnetic Stirrer combines controlled heating and magnetic stirring in one compact laboratory instrument.

The system is operated using a digital control CPU, which regulates heating up to 300°C and controls stirring speed through the keypad. The selected stirring speed is indicated on the display using a bar-graph indication.

The LMMS300 is also programmable, allowing the operator to set the objective temperature, hold temperature, stirring time and stirring speed. For more accurate temperature control, an ATC temperature probe can be connected and placed inside the glass container being stirred to measure and maintain the desired temperature.

5. Technical Specifications

6. Heating Performance

The LMMS300 provides a maximum plate-surface temperature of 300°C.

Temperature Accuracy

The microprocessor controls the heating system, while the ATC probe can be used to measure and maintain the desired temperature of the sample rather than relying only on the plate temperature.

7. Stirring Performance

The LMMS300 provides:

• Maximum speed: 1250 RPM
• Maximum volume: 2000 mL
• Digital speed control
• Keypad-based speed adjustment
• Speed indication on display
• Programmable stirring speed
• Programmable stirring time

This makes the unit suitable for controlled mixing and heating of laboratory solutions.

8. Automatic Temperature Control

The Automatic Temperature Control (ATC) function allows the temperature of the sample to be monitored directly.

How ATC Works

1. Connect the supplied ATC temperature probe.
2. Place the probe inside the glass container containing the sample.
3. Set the desired temperature.
4. The probe measures the sample temperature.
5. The control system regulates heating to maintain the desired temperature.

This provides more meaningful temperature control of the sample compared with relying solely on the hotplate surface temperature.

9. Programmable Operation

The LMMS300 allows the operator to configure:

• Objective temperature
• Hold temperature
• Stirring time
• Stirring speed

This programmable functionality makes the instrument suitable for repeatable laboratory heating and mixing procedures.

10. Control & Display

The LMMS300 uses a digital control CPU with an LCD display.

The control system provides:

• Temperature setting
• Temperature monitoring
• Digital stirring-speed control
• Stirring-speed indication
• Programmable operating parameters
• Timer control
• Automatic temperature control

The supplied catalogue also shows the instrument with a stand assembly for the ATC probe.

11. Applications

The LMMS300 is suitable for laboratory procedures requiring simultaneous heating and stirring, including:

• Solution preparation
• Reagent preparation
• Chemical mixing
• Sample heating
• Controlled laboratory reactions
