Product Overview

Laboratory Magnetic Stirrer

A laboratory magnetic stirrer is a versatile instrument used for liquid mixing, dissolution, suspension, and homogenization of reaction mixtures. It uses a magnetic stir bar to mix liquids without direct mechanical contact, helping reduce contamination risks associated with mechanical seals. Magnetic stirrers are widely used in chemical, biological, pharmaceutical, and materials science laboratories.

Working Principle

A motor rotates a magnet located beneath the stirring plate, driving the magnetic stir bar inside the container to rotate and generate fluid circulation for uniform mixing. Many models feature an integrated heating function and use a built-in PT1000 temperature sensor for precise temperature control. The maximum heating plate temperature can reach 300–350°C, depending on the model. Combined with a timer function, these instruments provide convenient simultaneous heating and stirring.

Applications

Laboratory magnetic stirrers are suitable for a wide range of applications, including chemical synthesis (reaction mixture mixing and catalyst dispersion), biopharmaceutical research (culture medium preparation and cell suspension), environmental monitoring (water sample mixing), food testing, and university teaching laboratories. They are particularly suitable for long-term, temperature-controlled stirring of small- to medium-volume samples.

Selection Guide

When selecting a laboratory magnetic stirrer, several factors should be considered. A stirring capacity of 1–30 L can accommodate applications ranging from small-scale experiments to pilot-scale work. A stepless speed range of 50–2,000 rpm allows adjustment for different liquid viscosities and mixing requirements. Memory programming with up to 10 program sets helps improve experimental repeatability, while RS485 remote control supports integration with automated systems. Some models offer reversible stirring to help prevent sediment accumulation. Other important considerations include heating power, stirring plate material (ceramic or stainless steel), and safety features such as overheat protection.

Customer Photos/ Customer Review

The laboratory purchased 20 heating magnetic stirrers at one time. The customer service was very professional and recommended suitable models based on the space on our experimental bench and the specifications of commonly used beakers.

Whether processing liquid samples or performing chemical reactions, the stirring effect is very uniform, extremely efficient, and the temperature control is also precise. It supports constant temperature stirring and the temperature error is controlled within ±0.5°C.

The running sound is very quiet, it does not shake when working, and it is stable even after being turned on for a long time. It is not easy to malfunction, which is quite good. A small disadvantage is that there is no free beaker.

The operation is very smooth, the speed adjustment range is wide, the magnet does not jump at low speeds, and the high-speed operation is also very stable. The digital speed display has clear readings and the stirring strength is sufficient, so that all types of aqueous solution samples can be mixed evenly.
