Double 10 liter oil ultra-thin magnetic stirrer CNC

Magnetic stirrers are usually used in laboratories to stir low viscosity liquids (such as water, solutions, etc.), while peanut oil, as a high viscosity non-polar liquid, its stirring effect will be affected by equipment design, operating parameters, and oil characteristics. The following is a specific analysis:

1. Working principle of magnetic stirrer

The magnetic stirrer drives the magnetic stirrer inside the container (usually a PTFE coated magnet) through a rotating magnet at the bottom, achieving contactless stirring. Its core advantage is to avoid mechanical seals and be suitable for sealing or high-temperature environments, but its stirring capacity is limited by the following factors:

• Stir size and shapeSmall size stirrers (such as 5mm) are suitable for low viscosity liquids, while high viscosity liquids require larger sizes (such as 20mm or more) or special shapes (such as paddle or anchor).

• speed rangeThe speed of a regular magnetic stirrer is usually 0-1500 rpm, and higher speeds are required for high viscosity liquids (which may require specialized equipment).

• Torque limitThe torque of magnetic coupling is limited, and high viscosity liquids may cause the agitator to stop or slip due to excessive resistance.

Feasibility of mixing peanut oil

• Low viscosity peanut oilIf the viscosity of peanut oil is low (such as close to edible oil standards) and the stirring amount is small (such as 100-500mL), a regular magnetic stirrer combined with a large-sized stirrer (such as 15-20mm) may achieve basic mixing, but the efficiency is low. Guoli Tian provides corresponding magnetic stirring series for customers with non intrusive oil stirring needs, and the entire ultra-thin series can stir oil samples.

• High viscosity or large amount of peanut oilSpecial high torque magnetic mixers (such as industrial grade or overhead mixers) are required, or mechanical mixers (such as paddle mixers) should be used instead.

3. Operational suggestions

• Device Selection：

• Laboratory grade: High torque magnetic stirrer (such as Guoli Tian ultra-thin series) is selected, paired with large-sized stirrer.

• Industrial grade: If a large amount or high viscosity peanut oil needs to be mixed, it is recommended to use a top mounted mechanical mixer (such as a paddle or anchor mixer).

• parameter adjustment：

• speedGradually increase from low speed (such as 200 rpm) to avoid stalling of the agitator.

• temperatureHeating can reduce the viscosity of peanut oil (such as 60-80 ℃), but it is necessary to ensure the temperature resistance range of the mixer.

• Stirring designChoose paddle or anchor agitator to enhance shear force.

• Safety precautions：

• Avoid friction between the agitator and the bottom of the container to generate heat (which may cause oil oxidation).

• Ensure that the container material is oil resistant (such as glass or stainless steel) to avoid plastic container deformation.

4. Alternative solutions

If the magnetic stirrer is not effective, you can consider:

• Mechanical mixerLike a paddle mixer, the mixing paddle is directly driven by a motor, resulting in greater torque.

• Ultrasonic stirringSuitable for small-scale mixing, but may generate heat.

• manual stirringFor small amounts of peanut oil, manual stirring may be more efficient.

The core advantages of multiple magnetic stirrers

1. Multi station design

• Usually equipped with 2-12 independent mixing positions, each mixing position can independently control the speed, temperature (if equipped with heating function), or mixing direction.

• Suitable for scenarios that require simultaneous processing of multiple samples or comparative experiments (such as drug dissolution, chemical synthesis, biological cultivation, etc.).

2. Contactless drive

• By driving the agitator with a bottom magnet, the risk of mechanical seal leakage is avoided, making it suitable for sealed containers or high temperature/high pressure environments.

3. uniformity

   The independently controlled mixing position ensures consistent mixing conditions for each sample, reducing batch differences.

   
   

   2、 Typical application scenarios

• 1. Chemical laboratory

• Parallel synthesisSimultaneously conducting multiple chemical reactions (such as catalyst screening and reaction condition optimization) to improve experimental efficiency.

• solution preparationQuickly mix multiple solutions (such as buffer solution, standard curve preparation) to ensure uniform concentration.

• Extraction/SeparationAccelerate the mixing and stratification of two-phase liquids (such as organic water phase).

• 2. Biological laboratory

• cell cultureStir multiple cell culture bottles simultaneously in the incubator to ensure even distribution of oxygen and nutrients.

• enzyme reactionControl the temperature and stirring speed of different enzyme reaction systems to study reaction kinetics.

• DNA/RNA extractionMixing the lysate with the sample to improve extraction efficiency.

• 3. Food and Drug Industry

• sample pretreatmentMixing multiple food or drug samples simultaneously (such as dissolution, emulsification, homogenization).

• stability test: Simulate the product stability under different stirring conditions (such as oil-water lotion and suspension).

• 4. Environmental monitoring

• Water sample analysisQuickly mix water samples and reagents (such as heavy metal detection, COD determination) to improve analysis speed.

• Soil extractionStir the soil and extract to accelerate the dissolution of organic matter or heavy metals.
