Let’s Dive into VWR Black Vacuum Rubber Tubing 8591 93/4″ Coil Length
The VWR Black Vacuum Rubber Tubing 8591 93/4″ Coil Length may seem like a humble piece of laboratory equipment, but it’s a critical component in many scientific and industrial applications. Manufactured by VWR, this tubing is designed to withstand vacuum pressures while maintaining flexibility and resistance to various chemicals. With its specific dimensions and material properties, it aims to offer a reliable solution for connecting different parts of a vacuum system.
My journey to this product began with a frustrating search for reliable tubing for a custom vacuum setup I was building for a freeze-drying project. I needed something robust enough to handle a significant vacuum without collapsing, yet flexible enough to route through tight spaces. Upon unboxing the VWR Black Vacuum Rubber Tubing 8591 93/4″ Coil Length, my initial impression was of sturdy, well-made tubing. The rubber felt dense and resilient, promising a good seal and resistance to kinking.
Compared to cheaper, generic rubber tubing I’d used in the past, the VWR offering immediately felt superior. I had previously considered silicone tubing for its flexibility, but silicone often lacks the chemical resistance and vacuum performance needed for my specific application. Ultimately, the VWR Black Vacuum Rubber Tubing 8591 93/4″ Coil Length was selected for its combination of durability, chemical resistance, and specific dimensions ideal for my project. My first impression was optimistic; the tubing appeared to be precisely what I needed to complete my vacuum setup.
Real-World Testing: Putting VWR Black Vacuum Rubber Tubing 8591 93/4″ Coil Length to the Test
First Use Experience
I tested the VWR Black Vacuum Rubber Tubing 8591 93/4″ Coil Length in my laboratory while setting up a small-scale freeze-drying system. The system involved connecting a vacuum pump to a drying chamber, and the tubing was essential for creating a leak-proof seal. During the initial pump-down, the tubing performed admirably, maintaining its shape without any noticeable collapse.
The laboratory environment presented a relatively clean setting, but the tubing was exposed to isopropyl alcohol during the cleaning process. It handled the exposure without any apparent degradation or swelling. The tubing was easy to cut and connect, and I didn’t need any specialized tools to achieve a secure fit. After the first use, I was very pleased with the ease of use and the performance under vacuum.
Extended Use & Reliability
After several weeks of consistent use, the VWR Black Vacuum Rubber Tubing 8591 93/4″ Coil Length has proven to be highly reliable. There are no signs of cracking or hardening. Routine cleaning with mild detergents hasn’t affected its flexibility or sealing capabilities.
The VWR tubing has exceeded my expectations in terms of durability. My previous experiences with lower-quality rubber tubing often led to premature failure due to cracking and loss of flexibility. This tubing feels significantly more robust and capable of withstanding long-term use.
Breaking Down the Features of VWR Black Vacuum Rubber Tubing 8591 93/4″ Coil Length
Specifications
- The VWR Black Vacuum Rubber Tubing 8591 93/4″ Coil Length boasts an inner diameter (I.D.) of 5/16 inches and an outer diameter (O.D.) of 13/16 inches. These dimensions are critical because they ensure compatibility with standard fittings commonly used in vacuum systems.
- It also features a 1/4 inch wall thickness, adding to its durability and resistance to collapse under vacuum pressure. This is a key specification that sets it apart from thinner-walled tubing, which may be more prone to deformation.
- This tubing is constructed from high-quality natural rubber, which provides a good balance of flexibility and chemical resistance. Natural rubber is known for its ability to maintain a seal under vacuum and withstand moderate exposure to acids and solvents.
- The manufacturer, VWR, states a durometer hardness of Shore A, 50. This indicates the rubber’s resistance to indentation, influencing its long-term durability and sealing effectiveness.
- The tubing has a tensile strength of 2500-3500psi, crucial for handling the stress associated with vacuum applications and potential stretching or bending. This ensures the tubing can withstand substantial force without tearing or failing.
