Non-Heating Magnetic Stirrer (DLAB MS-S)

PRIMARY CLINICAL & DIAGNOSTIC USES

1. General Solution Mixing and Reagent Preparation in Clinical Laboratories
Primary Use: Provides a non-heating, digital magnetic stirrer with a ceramic-coated or stainless steel work plate and a maintenance-free brushless DC motor, used for the efficient and homogeneous mixing of aqueous solutions, buffers, reagents, and clinical laboratory preparations, with a maximum stirring capacity of 20 liters and a speed range of 100 to 1500 rpm.

How it helps: For the clinical laboratory scientist and medical technologist, the MS-S’s maintenance-free brushless DC motor and powerful magnetic drive deliver consistent, reliable stirring performance ideal for preparing common laboratory reagents, buffers, and diluents. The digital display with 1 rpm resolution allows precise speed selection from gentle mixing to vigorous agitation, accommodating different liquid viscosities. The ultra-silent and vibration-free design minimizes distractions during critical work. For the patient, the consistent and reproducible mixing of reagents ensures the accuracy of diagnostic test results, supporting reliable clinical decision-making.

2. Sample Preparation for Water Quality and Environmental Monitoring
Primary Use: An ideal tool for general laboratories performing water quality analysis and environmental monitoring, the MS-S is used for mixing samples and reagents for key tests, such as Chemical Oxygen Demand (COD), heavy metal analysis, and total suspended solids measurement, and for preparing liquid cultures for microbiological analysis of environmental samples.

How it helps: For the environmental laboratory technician, the MS-S’s digital control allows precise, repeatable stirring conditions across multiple samples, ensuring consistent reagent mixing and sample homogeneity. The ceramic-coated or stainless steel work plate provides excellent chemical resistance, ensuring durability when exposed to various water quality testing reagents. For the public, reliable water quality analysis directly supports community health by ensuring safe drinking water and monitoring environmental pollution.

3. Dissolving Solids and Preparing Solutions for Drug and Food Analysis
Primary Use: Used for the efficient dissolution of solids and the preparation of standard solutions, buffers, and mobile phases in pharmaceutical and food analysis laboratories, ensuring homogeneity for quality control testing such as HPLC and UV-Vis spectrophotometry.

How it helps: For the pharmaceutical and food safety quality control analyst, the Non-Heating Magnetic Stirrer (DLAB MS-S) robust stirring action ensures that powders, tablets, or other solid samples are completely dissolved and mixed into solution before analysis. The brushless DC motor is maintenance-free, and the chemical-resistant top plate provides excellent durability against aggressive solvents and acids. For the pharmaceutical patient and consumer, accurate sample preparation is critical for verifying the potency of drugs and ensuring the safety and quality of the food supply.

4. Liquid Culture Mixing and Preparation in Clinical Microbiology
Primary Use: Enables the gentle yet thorough mixing of liquid cell cultures, microbial broths, and growth media in clinical microbiology laboratories to maintain a uniform cell suspension and optimize growth conditions, without the risk of heat damage to sensitive biological samples.

How it helps: For the clinical microbiology technologist, the MS-S’s digital speed control allows for precise agitation, ensuring that bacterial and yeast cultures are evenly oxygenated and mixed without damaging the cells. The brushless motor produces no sparks, making it safer for use in environments where flammable solvents or volatile reagents may be present. For the patient, the careful preparation of culture media and the incubation of samples are essential steps in the accurate identification of pathogenic microorganisms, leading to timely and appropriate antibiotic therapy.

SECONDARY & SUPPORTIVE USES

1. Electrochemical measurements: Provides stable and consistent stirring of solutions during electrochemical experiments, such as pH calibration and measurement, ion-selective electrode analysis, and titration, ensuring a uniform ion concentration around the electrode for fast, accurate readings. The digital speed control allows repeatable stirring conditions across multiple measurements.

2. Pharmaceutical quality control and dissolution testing: Used in pharmaceutical QC laboratories to prepare solutions and standard dilutions. The MS-S can be used as a stirring platform for dissolution test vessels, maintaining consistent agitation for drug release studies when paired with appropriate temperature control from a water bath.

3. Food and beverage quality analysis: Serves as an essential tool in food and beverage analysis laboratories for mixing food extracts, preparing chemical reagents, and dissolving samples before analysis for components such as caffeine, total polyphenols, vitamins, nitrates, and preservatives.

4. Preparation of buffers, mobile phases, and standard solutions: Prepares precise chemical solutions for high-performance liquid chromatography, gas chromatography, and other analytical chemistry techniques by thoroughly dissolving solids and ensuring a homogeneous mixture, with digital speed control for repeatability.

5. Titration and analytical chemistry: Provides continuous and uniform sample stirring during manual and automated titrations, which is critical for the accurate determination of reaction endpoints and the reproducibility of analytical results. The digital display allows the user to set and document the exact stirring speed used.

6. Heavy metal and trace element analysis: Prepares liquid and digested samples for heavy metal analysis using atomic absorption spectroscopy or inductively coupled plasma mass spectrometry by maintaining solid particles in suspension for accurate sampling, with chemical-resistant top plate for acidic solutions.

7. BOD and COD water testing: Prepares samples and reagents for essential water quality tests like Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) by ensuring the complete dissolution and uniform mixing of the strong oxidizing agents and other chemicals used, with consistent stirring for reproducible results.

8. General and educational laboratory use: Serves as an economical, user-friendly digital teaching tool for demonstrating the principles of solution preparation, mixing, and chemical reaction kinetics in high school and university chemistry and biology laboratory courses, with an intuitive interface.

9. Research and development: Provides a reliable, hands-on stirring solution for research scientists performing small-scale chemical synthesis, media optimization, or other reaction studies requiring precise, repeatable agitation over extended periods, with the ability to run continuously for hours.

10. Viscosity testing of liquid samples: Maintains liquid samples under controlled, constant stirring for viscosity measurement using viscometers, supporting quality control in pharmaceutical, chemical, and food industries where sample homogeneity is critical.
