Magnetic Stirrer ONiLAB Lab Stirrers 3L Compact Brushless Design

Description

Product Overview

The ONiLAB Magnetic Stirrer is engineered for laboratories, research facilities, and small‑scale production environments where precise, reliable mixing is essential. Built around a maintenance‑free brushless DC motor, the unit delivers smooth, stepless speed control from 0 to 2000 rpm, allowing users to fine‑tune agitation for a wide range of liquids, from low‑viscosity solvents to moderately viscous suspensions. The magnetic coupling is powered by four high‑quality stainless‑steel stir bars, each designed to provide consistent torque transfer while resisting corrosion.

Its 3 L maximum stirring volume is housed within a robust PET (polyethylene terephthalate) top that offers excellent chemical resistance, easy cleaning, and a clear view of the mixing process. The PET material is also lightweight, contributing to the overall portability of the device. The compact chassis measures 9.25 × 6.65 × 3.31 inches and weighs just 1.21 lb, making it easy to move between benches or transport to field sites. Power is supplied via a 3 m, 12 V AC cord, enabling flexible placement in various lab configurations.

Technical specifications include a brushless DC motor rated for continuous operation, a digital speed controller with an LED display, and a safety interlock that prevents the motor from running when the lid is removed. The unit complies with CE safety standards and has earned a solid 4.4‑star rating from 47 verified customer reviews, reflecting its reliability and performance in real‑world applications.

Usage

Designed for versatility, the ONiLAB Magnetic Stirrer excels in a variety of settings. In academic and industrial laboratories, it provides consistent agitation for chemical synthesis, sample preparation, and analytical testing. Researchers can use it to maintain homogeneous solutions during kinetic studies, ensuring reproducible results across experiments.

Beyond traditional lab work, the stirrer is well suited for the brewing and fermentation community. Homebrewers and small‑scale craft breweries can employ the device to dissolve yeast starters, mix malt extracts, or maintain temperature‑controlled fermentations. Its quiet operation and low power consumption make it an unobtrusive addition to any brewing setup.

In agricultural and environmental testing labs, the stirrer assists in preparing nutrient solutions, pesticide suspensions, and soil extract samples. Its chemical‑resistant PET top simplifies cleanup after handling potentially hazardous reagents, reducing cross‑contamination risks.

Healthcare and medical research facilities benefit from the stirrer’s ability to gently mix cell culture media, buffer solutions, and diagnostic reagents without introducing shear stress that could damage delicate biological samples.

FAQ

What types of liquids can the stirrer handle?

The device is suitable for low to moderately viscous liquids, including aqueous solutions, organic solvents, and mild suspensions. It is not recommended for highly viscous substances such as thick gels or heavy oils.

Can the stirrer be used without a lid?

For safety, the motor will not operate if the PET top is removed. This interlock protects users and prevents accidental spillage during operation.

Is the stirrer compatible with standard laboratory glassware?

Yes, the magnetic coupling works with most standard beakers, flasks, and Erlenmeyer vessels that have a flat bottom. The 3 L capacity accommodates a wide range of container sizes.

How do I clean the PET top after use?

Simply rinse the PET top with water or an appropriate solvent, then wipe dry with a lint‑free cloth. The material resists most chemicals, making cleanup quick and hassle‑free.

What is included in the package?

The package contains the magnetic stirrer unit, a 3 m power cord, four stainless‑steel stir bars, and a user manual with setup instructions.
