Let’s Dive into VWR Reservoir Ambr Glass 250ML 844082
The VWR Reservoir Ambr Glass 250ML 844082 is a crucial piece of laboratory equipment designed for sample collection and preservation. This amber glass reservoir, manufactured by VWR, boasts features like a magnetic closure, a hinged top, and a “Smart Cap” meter, making it a seemingly ideal solution for sensitive sample handling. I’ve spent years dealing with samples in the field, often battling contamination and degradation, which is why this product immediately caught my eye.
My work frequently involves collecting environmental samples in remote locations. The primary issue I face is maintaining sample integrity from collection to analysis. I was looking for a reservoir that offered superior protection against light degradation and accidental contamination.
Upon unboxing, the VWR Reservoir Ambr Glass 250ML 844082 felt substantial and well-constructed. The amber glass has a reassuringly thick feel, and the magnetic closure seems like a genuinely smart design choice. The hinged top operates smoothly, and the integrated “Smart Cap” meter looks promising.
Compared to standard clear glass beakers and disposable plastic containers, the VWR Reservoir promised a significant upgrade in terms of sample protection. I also considered the Pyrex amber glass beakers and Kimble Chase media bottles. I chose the VWR Reservoir Ambr Glass 250ML 844082 because of its unique features like the magnetic closure and Smart Cap.
My initial reaction was cautiously optimistic. I was excited about the potential for improved sample integrity, but also slightly concerned about the practicality of using a glass reservoir in rugged field conditions. The $109.99 price tag set a high bar for performance.
Real-World Testing: Putting VWR Reservoir Ambr Glass 250ML 844082 to the Test
First Use Experience
I field-tested the VWR Reservoir Ambr Glass 250ML 844082 during a water quality monitoring project in a remote mountain watershed. The reservoir was used to collect stream water samples for dissolved organic carbon (DOC) analysis. These samples are extremely sensitive to light and contamination.
The reservoir performed admirably in damp conditions. The magnetic closure ensured a tight seal, preventing any accidental spillage or contamination during transport in my backpack. The hinged top, which can be easily opened with one hand, proved useful when I was taking samples while holding my position on a steep slope.
The initial experience was very positive, and the features felt thoughtfully designed. The sample integrity, as measured by lab analysis, seemed better than with my previous sampling containers.
Extended Use & Reliability
After three months of regular use, the VWR Reservoir Ambr Glass 250ML 844082 has held up remarkably well. There are no signs of cracks or significant wear and tear on the glass. The magnetic closure continues to function reliably.
Cleaning the reservoir is surprisingly easy. A simple rinse with distilled water is usually sufficient, and the wide mouth facilitates thorough cleaning. The glass does require careful handling to avoid breakage, but this is an acceptable trade-off for its superior sample protection.
In comparison to my previous use of disposable plastic containers, the VWR Reservoir has significantly improved the reliability of my sample collection process. The amber glass provides far better protection against light degradation. The magnetic closure has eliminated accidental contamination issues.
Breaking Down the Features of VWR Reservoir Ambr Glass 250ML 844082
Specifications
- Description: VWR RESERVOIR AMBR GLASS 250ML. This reservoir is specifically designed for collecting and storing samples that are sensitive to light.
- Material: Amber Glass. The amber glass provides crucial protection against UV and visible light, preventing degradation of light-sensitive samples.
- Capacity: 250ML. This volume is suitable for a range of sampling needs, balancing portability with sufficient sample volume for many analyses.
- Closure: Patented Automatic Magnetic Closure. This offers an extra layer of safety against accidental opening and contamination.
- Top: Hinged Top. This feature allows for easy one-handed operation during sample collection, especially useful in field conditions.
- Additional Features: Metered metal catch, reusable “Smart Cap” meter, all-glass stopper with “Forward Flow” design, compatibility with magnetic stirring attachment, and magnetic sensor in the InScentTM mouse trap design.
These specifications are critical because they directly address the primary concerns of sample collection: preventing contamination and degradation. The amber glass protects samples from light, the magnetic closure ensures a secure seal, and the hinged top facilitates easy use in the field.
Performance & Functionality
The VWR Reservoir Ambr Glass 250ML 844082 excels at its primary job of preserving sample integrity. The amber glass effectively blocks light, and the magnetic closure prevents leaks and contamination. The Smart Cap is an interesting touch, but its actual utility in the field is limited, as I typically rely on other calibrated instruments for precise measurement.
The reservoir’s strengths lie in its robust construction and thoughtful design features that prioritize sample protection. One potential area for improvement is the weight; the glass reservoir is heavier than plastic alternatives, which can be a consideration for extended field work.
The VWR Reservoir meets and even exceeds my expectations for a high-quality sample collection container. It significantly reduces the risk of sample degradation and contamination.
Design & Ergonomics
The VWR Reservoir is constructed from durable amber glass. The glass feels thick and robust, providing confidence in its ability to withstand typical field handling.
The design is generally user-friendly, although the glass construction necessitates careful handling. The hinged top and magnetic closure are intuitive to use.
Durability & Maintenance
The amber glass construction suggests that the VWR Reservoir is built to last. The glass is resistant to most chemicals.
Cleaning and maintaining the reservoir is straightforward. A simple rinse with distilled water is typically sufficient.
Accessories and Customization Options
The product description mentions compatibility with a magnetic stirring attachment. This could be useful for maintaining homogeneity of the sample prior to sub-sampling.
I am unaware of any readily available customization options for the VWR Reservoir. Its design is fairly specific to its intended purpose.
Pros and Cons of VWR Reservoir Ambr Glass 250ML 844082
