Let’s Dive into VWR Stirring Elements, IKA Works 513500 R 1300 Dissolver Stirrer
The VWR Stirring Elements, IKA Works 513500 R 1300 Dissolver Stirrer is a laboratory workhorse, a piece of equipment designed to tackle the often-underappreciated but critical task of mixing and dissolving. Manufactured by IKA Works, a name synonymous with quality laboratory equipment, this stirrer is specifically engineered for applications requiring high turbulence and shearing forces. It is crucial for effective particle reduction. The R 1300 Dissolver Stirrer boasts a stainless-steel construction and a design optimized for radial flow, promising efficient and consistent results.
My work in formulating specialized coatings demanded a stirrer capable of handling viscous liquids and achieving homogenous mixtures quickly. I needed something that wouldn’t bog down when dealing with high solids content or create dead zones within the mixing vessel. My previous stirrers lacked the power and design to adequately disperse pigments and additives, leading to inconsistent product quality and wasted time.
Unboxing the VWR Stirring Elements, IKA Works 513500 R 1300 Dissolver Stirrer, my initial impression was one of robust quality. The stainless steel felt solid and well-finished. It immediately conveyed a sense of durability and precision engineering.
I was choosing between the IKA Works Dissolver Stirrer, a Heidolph RZR 2051 control, and a simple overhead stirrer from VWR. The IKA Works model edged out the others due to its specific emphasis on high shear mixing, a crucial requirement for my application. The VWR stirrer, while cost-effective, lacked the power. The Heidolph, though powerful, was significantly more expensive.
My first impression was cautiously optimistic. The build quality and design suggested it would be a significant upgrade. Only rigorous testing would reveal if it truly lived up to its promises.
Real-World Testing: Putting VWR Stirring Elements, IKA Works 513500 R 1300 Dissolver Stirrer to the Test
First Use Experience
I first tested the VWR Stirring Elements, IKA Works 513500 R 1300 Dissolver Stirrer in my coatings lab, using it to formulate a high-solids epoxy primer. This application involved dispersing titanium dioxide pigment into a viscous resin blend. The goal was to achieve a smooth, uniform dispersion without any settling or agglomeration.
The stirrer performed admirably, even when the mixture became increasingly thick. The radial flow pattern efficiently pulled material from both the top and bottom of the mixing vessel. It created a powerful vortex that quickly incorporated the pigment.
The ease of use was a pleasant surprise. Adjusting the speed was intuitive. The powerful motor allowed me to easily control the intensity of the mixing. I experienced no issues with overheating or motor strain.
The most notable surprise was the dramatic reduction in mixing time. Compared to my previous setup, the IKA Works stirrer achieved a homogenous mixture in about half the time.
Extended Use & Reliability
After several months of regular use, the VWR Stirring Elements, IKA Works 513500 R 1300 Dissolver Stirrer continues to perform reliably. I have used it with a variety of formulations, ranging from thin solvents to thick pastes. It has consistently delivered excellent mixing results.
The durability is impressive. There are no signs of wear and tear on the stainless-steel shaft or the stirrer head. The motor runs smoothly and quietly.
Maintenance is straightforward. Cleaning the stirrer head after use is simple. The stainless steel is resistant to most solvents and chemicals.
Compared to my previous experiences, the IKA Works stirrer is a significant improvement. It is more powerful, more efficient, and more reliable than any other stirrer I have used. It has become an indispensable tool in my lab.
Breaking Down the Features of VWR Stirring Elements, IKA Works 513500 R 1300 Dissolver Stirrer
Specifications
- Description: R 1300 Dissolver Stirrer: This specifies the type of stirring element, designed for dissolving and particle reduction. This design is crucial for applications requiring high shear forces.
- Shaft Diameter: 8mm: The shaft diameter determines compatibility with overhead stirrer motors. A larger diameter shaft typically indicates greater strength and stability.
- Stirrer Head Diameter: 8 cm (3 1/8 in): The stirrer head diameter impacts the area of mixing and the turbulence generated. This size is suitable for medium-sized vessels.
- Shaft Length: 35 cm (13 3/4 in): The shaft length dictates the depth to which the stirrer can reach within the mixing vessel. This length is appropriate for standard lab beakers and flasks.
- Maximum Speed: 2000 rpm: The maximum speed determines the intensity of the mixing action. Higher speeds are generally needed for viscous materials or rapid dissolution.
- IKA Works No.: 513500: This is the IKA Works specific product number. It allows for easy identification and reordering.
These specifications are critical for ensuring the stirrer is appropriate for the intended application. The high maximum speed and dissolver head design make it ideal for tasks requiring vigorous mixing and particle size reduction.
Performance & Functionality
The VWR Stirring Elements, IKA Works 513500 R 1300 Dissolver Stirrer excels at creating high levels of turbulence and shear. This is essential for quickly dissolving solids, dispersing pigments, and creating homogenous mixtures. The radial flow pattern efficiently draws material from both the top and bottom of the vessel, preventing settling and ensuring thorough mixing.
A significant strength is its ability to handle viscous materials. The powerful motor and robust design prevent the stirrer from bogging down. A potential weakness, though minimal, is the relatively small stirrer head diameter. For very large vessels, a larger head might be more efficient.
