product key technologies
Introduction & Principle
The compact digital magnetic stirrer is a fundamental benchtop device designed for small-volume liquid blending. It is primarily applied to agitate low-viscosity fluids as well as solid-liquid suspensions.
It operates based on the magnetic rule that unlike magnetic poles attract while like poles repel. A rotating magnetic field drives the magnetic stir bar inside the vessel to spin, so as to homogenize the contents.
Advantage
1. Compact in appearance with straightforward, user-friendly operation.
2. Carbon-brushless motor design for extended service life.
3. Continuously variable speed control with a broad speed adjustment range.
4. Powerful magnetic force, effectively preventing stir bar jumping.
5. Portable form factor to accommodate diverse experimental requirements.
Working Surface, Mixing Capacity and Speed Selection
This micro digital magnetic stirrer is engineered for small-scale liquid mixing in laboratory settings. It supports mixing volumes ranging from 10 mL up to 2000 mL, covering most common sample preparation workflows. Featuring a 130 × 130 mm working plate, it provides a compact platform to hold compatible lab glassware.
Users can modify stirring conditions to suit various liquids and experimental protocols thanks to the adjustable speed range of 0–1800 rpm. Start at a low speed and increase it gradually until the desired mixing effect is obtained for improved mixing stability.
Take into account the following aspects while choosing a small magnetic stirrer:
Working surface: Verify that the 130 x 130 mm working area can accommodate the vessel base.
Sample volume: Choose a model with a reported capacity range of 10–2000 ml based on the actual liquid volume.
Stirring speed: Depending on the size of the vessel, the stir bar, and the viscosity of the liquid, select an appropriate speed.
Stir bar compatibility: Use a magnetic stir bar appropriate for the vessel and sample volume.
Operating stability: Steer clear of abrupt speed increases that could throw off the stir bar's synchronization.
Application
This compact digital magnetic stirrer fits routine lab workflows for educational institutions, analytical testing and quality control departments, benefiting from its space-saving structure and capacity for small-volume blending.
1. Biopharmaceutical and life science sample preparation
This mini magnetic stirrer works well for blending lab reagents, dissolving solutes and making small-quantity buffer solutions in biotechnology research labs. Its small footprint suits workstations running several sample-prep operations at the same time. Operators can set stirring parameters matched to sample properties and experimental schemes when handling sensitive biological specimens.
2. Chemical preparation and titration work
Magnetic agitation supports sample makeup and calibration work during chemical analysis. Its adjustable speed range allows users to set proper stirring speeds to fit different laboratory test procedures.
3. University teaching laboratories
Its slim form is ideal for teaching labs, where students prepare basic solutions, formulate reagents and carry out introductory chemistry experiments. The small footprint also makes it easy to place multiple units on shared lab bench space.
4. Routine analysis and quality inspection
QC laboratories can adopt this mini stirrer for small-batch sample preparation, solution homogenization and regular analytical tests. Model selection should be based on target operating parameters and sample volumes.
Note: Standard mini magnetic stirrers do not come with built-in heating by default. If heating is required for your tests, please select a heated magnetic stirrer instead.
Panel Protection and Routine Cleaning
When carrying out titration training and mixed-sample preparation tasks, liquid may accidentally splash during sample transfer, stirring, or handling near the equipment. When selecting a compact digital magnetic stirrer for such work, users should take into account the layout of the control panel, surface cleaning protocols, and guidelines issued by the manufacturer.
Prior to placing an order, check if the selected unit features a splash-proof control panel, protective cover or sealing construction, together with an official IP protection grade. These technical parameters apply to the complete device and cannot be judged merely based on its outer look.
To clean the equipment after use, power it down and cut off the power supply following the manufacturer's guidance. Wipe away spilled liquid promptly using approved cleaning methods, and make sure liquids cannot seep into control keys, display gaps, ports or ventilation openings.
Avoid washing the unit under running water or submerging it, unless the manufacturer has clearly stated that this operation is permitted. If your work often involves splashing liquids, wet sample preprocessing, or operation beside sinks, ask for the safety specifications of the specific model before purchase.
For labs with defined sanitation standards or special environmental demands, share details about the expected exposure conditions. Our team can then help confirm which configuration is suitable.

Selection of Conventional Magnetic Stirrer Rotor
Place the vessel holding the liquid sample on the base of the magnetic stirrer. Once the unit is powered on, a rotating magnetic field forms above the base. This field spins the stir bar inside the vessel, creating a liquid vortex for mixing. Accordingly, selecting a stirrer with sufficient magnetic strength is essential to obtain satisfactory stirring performance.
FAQ
1. What is the mixing potential of the mini digital magnetic stirrer?
The listed mixing capability of the QiweiLab mini digital magnetic stirrer sequence is 10–2000 mL. Actual overall performance relies upon on the liquid properties, vessel dimensions, stir bar size, and magnetic coupling conditions. For purposes close to the decrease stop of this range, affirm the minimal realistic working quantity with the supposed vessel and stir bar.
