What are the advantages of an inductive magnetic stirrer?

Inductive magnetic stirrers offer wear-free operation due to the absence of moving parts, resulting in quiet performance and reduced maintenance requirements compared to motor-driven stirrers.

Can this stirrer handle viscous liquids?

While suitable for a wide range of laboratory liquids, the effectiveness with highly viscous liquids will depend on the specific viscosity and the size of the stirring bar used. Buyers should consult the seller for specific performance data.

Is it possible to control each stirring position independently?

The 'direct-controlled' feature on this model typically refers to a single control for all 15 positions, ensuring synchronous stirring. Independent control per position is usually found on more specialised, higher-end units.

What kind of vessels can be used with this stirrer?

This type of magnetic stirrer is compatible with standard laboratory glassware such as Erlenmeyer flasks, beakers, and bottles, provided they are suitable for magnetic stirring and fit the stirring plate.

What maintenance is typically required for this equipment?

Due to the inductive drive, maintenance is generally low, primarily involving routine cleaning of the stirring surface and ensuring the unit is kept free from spills and dust.

The unit is in full working condition and is ready for immediate use

The Variomag Poly 15 is a precision-engineered, 15-position direct-controlled magnetic stirrer built for laboratory applications requiring simultaneous mixing of multiple samples. Developed by Variomag-USA (2mag GmbH, Germany), this stirrer is ideal for chemical, microbiological, biotechnical, and medical environments.

Core Features

Direct-Controlled Operation: Offers simple, immediate speed control for easy use.

Inductive Drive: Wear-free and low-maintenance magnetic induction ensures quiet, long-lasting operation.

Digital Speed Control: Microprocessor-based for consistent performance, with memory recall for repeated tasks.

Soft Start Function: Prevents splash and ensures gentle acceleration to protect magnetic coupling.

Simultaneous Stirring: Ideal for processing multiple Erlenmeyer flasks or beakers at once—up to 15 × 250 mL or 6 × 1 L vessels.

Typical Applications

The POLY 15 is designed for a wide range of laboratory tasks, such as:

Growing micro-organisms (e.g., aeration and culturing bacterial cultures)

Dissolving nutrient media and solids

Preventing settling of suspended particles

Performing titrations

General liquid mixing in R&D, pharma, food science, and education labs
