Let’s Dive into VWR Red Vacuum Rubber Tubing 9777 50″ Coil Length
The VWR Red Vacuum Rubber Tubing 9777 50″ Coil Length isn’t exactly the kind of gear you’d find strapped to a plate carrier or tucked into a bug-out bag. This is a specialized piece of laboratory equipment, but my decade of experience has taught me that even the most niche tools can find unexpected applications in the field. VWR is a well-known supplier of lab equipment, and this tubing promises a balance of quality and value.
My initial interest stemmed from a unique need during a remote research project. I needed a reliable way to create a makeshift vacuum system for collecting delicate samples, and standard tubing just wouldn’t cut it. I was looking for something with robust walls, excellent resilience, and the ability to withstand significant pressure differentials.
The VWR Red Vacuum Rubber Tubing 9777 50″ Coil Length arrives neatly coiled, its bright red color immediately noticeable. The rubber feels substantial, with a noticeable thickness to the walls. It’s immediately apparent that this isn’t your average hardware store tubing.
Compared to standard silicone tubing or the thinner-walled latex options, the VWR tubing is in a different class. It’s clearly designed for applications where maintaining a vacuum is paramount. I chose this particular model because of the specified wall thickness and the positive reviews regarding its tensile strength.
My first impression was a mix of relief and cautious optimism. The quality seemed evident, but I was eager to put it to the test in a real-world scenario. At a price of almost $2000, this stuff better work like a charm.
Real-World Testing: Putting VWR Red Vacuum Rubber Tubing 9777 50″ Coil Length to the Test
First Use Experience
My initial testing ground was a makeshift lab set up in a remote field station during that research project. I needed to create a closed system for collecting volatile organic compounds (VOCs) from soil samples. The tubing was used to connect a vacuum pump to a collection chamber.
The VWR Red Vacuum Rubber Tubing 9777 50″ Coil Length performed admirably, maintaining a consistent vacuum even under varying temperature conditions. Its thick walls prevented collapse, a common issue with thinner tubing. There was a slight rubbery odor initially, but it dissipated quickly.
Getting the tubing onto the fittings was initially a bit of a struggle, due to its thickness and rigidity. However, a bit of silicone lubricant solved the problem. There were no leaks or any signs of deformation after the first use.
Extended Use & Reliability
After several weeks of continuous use in the field, the VWR Red Vacuum Rubber Tubing 9777 50″ Coil Length continued to impress. It showed no signs of cracking or degradation, even after being exposed to sunlight and fluctuating humidity. The bright red color also made it easy to spot in cluttered environments.
The tubing proved remarkably durable, resisting abrasion from rough surfaces and accidental impacts. Cleaning was simple, requiring only a wipe-down with a damp cloth. The resilience of the rubber allowed it to return to its original shape even after being compressed or bent.
Compared to my previous experiences with standard vacuum tubing, the VWR product was a significant upgrade. It delivered superior performance, reliability, and durability, justifying the higher price point. I was confident that the VWR Red Vacuum Rubber Tubing 9777 50″ Coil Length would be a valuable asset for any application requiring a reliable vacuum seal.
Breaking Down the Features of VWR Red Vacuum Rubber Tubing 9777 50″ Coil Length
Specifications
- I.D. x O.D.: 3/4 in. x 1 1/2 in. These dimensions are crucial for compatibility with standard laboratory fittings and equipment.
- Wall Thickness: 3/8 in. This is a critical specification, as it determines the tubing’s ability to withstand vacuum pressure without collapsing.
- Coil Length: 50 in. The 50-inch length provides sufficient material for various applications and allows for some flexibility in setup.
- Material: Natural rubber. The use of natural rubber offers high resilience, good tensile and tear strength.
- Durometer Hardness: Shore A, 50. A durometer of 50 Shore A indicates a moderate level of hardness, providing a balance of flexibility and resistance to deformation.
- Tensile Strength: 2000-2600psi. This impressive tensile strength ensures that the tubing can withstand significant stress without tearing or breaking, essential for maintaining a reliable vacuum seal.
These specifications are essential because they directly impact the performance and reliability of the tubing. A thicker wall and high tensile strength guarantee the tubing can maintain a strong vacuum, even under demanding conditions. The durometer hardness also plays a role, striking the correct balance between flexibility for easy manipulation and rigidity to prevent collapse.
Performance & Functionality
The VWR Red Vacuum Rubber Tubing 9777 50″ Coil Length excels at its primary job: maintaining a reliable vacuum. The thick walls prevent collapse, ensuring consistent suction. Its resilience and tensile strength make it resistant to tearing or punctures.
The main strength is its ability to hold a strong vacuum without any noticeable leaks or deformations. One area for potential improvement is the initial rigidity, which can make it difficult to attach to fittings without lubrication. Overall, the tubing meets and exceeds expectations for its intended purpose.
Design & Ergonomics
The build quality is excellent, with a uniform wall thickness and smooth inner surface. The natural rubber is durable, yet still retains a degree of flexibility. The bright red color provides excellent visibility in lab or field settings.
The tubing is relatively user-friendly, although the initial rigidity can pose a minor challenge. A heat gun could be used to warm the rubber and improve flexibility.
Durability & Maintenance
The VWR Red Vacuum Rubber Tubing 9777 50″ Coil Length is built to last. The thick walls and high tensile strength ensure resistance to wear and tear. Regular cleaning with a damp cloth is typically sufficient to maintain its performance.
Repairing the tubing is possible in some cases, but it is generally recommended to replace damaged sections. This is especially crucial when dealing with vacuum systems, where even minor leaks can significantly impact performance.
Accessories and Customization Options
The VWR Red Vacuum Rubber Tubing 9777 50″ Coil Length doesn’t come with any specific accessories. Its primary customization option lies in cutting it to the desired length for a particular application. It’s compatible with standard laboratory fittings and connectors, allowing for easy integration into existing setups.
While it doesn’t support traditional “customization” in the sense of adding aftermarket parts, its compatibility with various connectors makes it adaptable to a wide range of experimental designs. Clamps, connectors and adapters from brands like Swagelok and Cole-Parmer work seamlessly with the VWR tubing.
