Let’s Dive into VWR Vial Scint Gls 20ML CS500 74503 20
The VWR Vial Scint Gls 20ML CS500 74503 20, manufactured by VWR, promises a reliable solution for scintillation counting needs. These vials are designed to be reusable, constructed from virgin polystyrene, and boast a baked-on finish to prevent sample contamination. The product aims to deliver a durable and chemically inert container for sensitive scientific applications.
My decade-plus in tactical gear might seem an odd pairing, but my work often intersects with environmental testing, specifically analyzing soil and water samples for contaminants. The challenge was consistently finding reliable vials that wouldn’t interfere with readings, were easy to handle in the field (often gloved), and could withstand multiple uses without compromising integrity. The VWR Vial Scint Gls 20ML CS500 74503 20 appeared to address all three.
Upon unboxing, the vials felt surprisingly lightweight yet sturdy. The polystyrene material had a smooth, clean finish, and the wide mouth was immediately appealing for ease of access. The packaging was simple but effective, ensuring the vials arrived undamaged.
Compared to standard polypropylene vials I’ve previously used from Fisher Scientific and Kimble Chase, the VWR vials felt noticeably more robust. While the others were cheaper, they often showed signs of wear after a few uses and sometimes even leached chemicals, skewing results. I chose the VWR Vial Scint Gls 20ML CS500 74503 20 because of the promise of reusability and minimal chemical interference, crucial for accurate testing.
My first impression was one of cautious optimism. The price point of $479.99 for a case of 500 is significantly higher than standard disposable vials. However, if the reusability and reliability claims hold true, the long-term cost savings and data integrity would make it a worthwhile investment.
Real-World Testing: Putting VWR Vial Scint Gls 20ML CS500 74503 20 to the Test
First Use Experience
My initial field test involved collecting water samples from a potentially contaminated site near an old industrial park. The VWR Vial Scint Gls 20ML CS500 74503 20 performed admirably. The wide mouth made it easy to transfer samples even while wearing thick nitrile gloves, preventing spills and minimizing exposure risk.
The vials were used in both wet and dry conditions. Even with condensation forming on the outside, the grip remained secure. No leaks were detected, and the closures held tight during transport.
The vials were incredibly easy to use; no special preparation was needed. The size was perfect for my standard sample volumes. After the first use, a simple wash with distilled water was sufficient to clean them.
The only initial surprise was the static cling of the polystyrene material. It attracted dust easily, requiring a quick wipe before sealing to avoid introducing external contaminants.
Extended Use & Reliability
After three months of regular use, the VWR Vial Scint Gls 20ML CS500 74503 20 vials have proven to be exceptionally durable. Despite being repeatedly washed and subjected to temperature fluctuations, there are no signs of cracking or degradation. The baked-on finish continues to prevent any visible discoloration or staining.
The vials have been subjected to some rough handling, including being jostled in a truck bed on bumpy roads. They have remained intact without any issues. After each sampling cycle, the vials are cleaned and autoclaved.
Maintenance is remarkably straightforward. A simple rinse with distilled water is generally sufficient for routine cleaning. For more stubborn residues, a mild detergent solution works effectively without damaging the vial’s surface.
In comparison to my previous reliance on single-use plastic vials, the VWR Vial Scint Gls 20ML CS500 74503 20 vials have far exceeded my expectations. The cost savings from reusability, coupled with the increased reliability and ease of use, have made them an invaluable asset in my fieldwork.
Breaking Down the Features of VWR Vial Scint Gls 20ML CS500 74503 20
Specifications
Description: VWR VIAL SCINT GLS 20ML CS500 – This is the core identifier for the product, specifying its use as a scintillation vial, the Manufacturer (VWR), the glass-like polystyrene material, the volume (20ML), and the quantity per case (CS500). This matters because it precisely defines the vial’s purpose and scale.
Reusable Aluminum Vials: Though technically polystyrene, the “aluminum vials” wording refers to the reflective properties of the vials used in scintillation counting. Reusability greatly reduces waste and long-term costs.
Virgin Polystyrene: Made from pure, unused polystyrene, free from lubricants, metals, or fillers. This ensures the vial won’t introduce contaminants that could skew readings and is therefore essential for accurate scintillation counting.
Baked-On Finish: The baked finish inside and out prevents chemical reactions and sample clouding. This maintains the integrity of the sample, ensuring results are consistent and reliable.
Radiation-Hardened Chromium Oxide (RCRA) Finish: Sterilized with a RCRA finish, the vials offer an excellent barrier to both visible and NIR radiation. The RCRA finish ensures the vials are safe to handle and that they will not degrade or release harmful substances during use.
Wide-Mouth Design: Allows easy access with or without gloves. This facilitates faster and safer sample handling in both laboratory and field environments.
Narrow Shoulder and Calibrated Curve: Facilitates use with a viscometric scale. Useful for aging the vial and determining its suitability for continued use.
Polycarbonate and Brass Closure: Provides financial security and easy recycling. This provides a secure seal during handling and transport and promotes sustainable disposal practices.
Steam Autoclavable: Can be sterilized via steam autoclaving with samples inside. Ensures that vials can be thoroughly cleaned between uses, preventing cross-contamination and improving data reliability.
