Breaking Down the Features of Medegen Medical Vwr Container Speci 90CC CS200 PC4090-200S Vwr Container Speci 90CC CS200, Case of 200

Specifications

The Medegen Medical Vwr Container Speci 90CC CS200 PC4090-200S Vwr Container Speci 90CC CS200, Case of 200 is built with specific laboratory and field needs in mind. Its core specification is a 90mL (90cc) capacity, which is a standard and highly practical volume for sample collection. The material of the container is break-resistant polypropylene, known for its chemical resistance and durability.

Crowning the container is a blue polyethylene closure, designed to provide superior leak resistance. This closure system is critical for maintaining sample integrity and preventing spills during transport. The product is supplied sterile, ensuring that samples are not contaminated upon collection, a vital aspect for accurate analysis.

The container is sold in a Case of 200 units, offering excellent value for bulk purchasers or regular users. The part number, PC4090-200S, clearly identifies this specific configuration. These specifications are not just numbers; they translate directly into practical benefits in the field and lab. The 90mL capacity is ideal for a range of tests, from water quality assessments to basic biological sampling. The break-resistant polypropylene means reduced risk of breakage and contamination, a common issue with more brittle plastics.

The superior leak resistance afforded by the blue polyethylene closure is perhaps the most crucial functional specification. This feature directly impacts the reliability of your sample, preventing loss or contamination due to movement or tipping. Being supplied sterile eliminates a significant preparation step and guarantees a clean starting point, which is essential for any sensitive testing. The bulk packaging in a Case of 200 also ensures that you have a sufficient supply on hand for extensive field operations or high-volume laboratory work.

Performance & Functionality

In terms of raw functionality, the Medegen Medical Vwr Container Speci 90CC CS200 PC4090-200S Vwr Container Speci 90CC CS200, Case of 200 performs its intended job exceptionally well. The primary function, containing and securely sealing a sample, is executed with impressive reliability. The break-resistant polypropylene is not just a marketing term; it translates to a container that can withstand accidental knocks and drops without catastrophic failure.

The superior leak resistance is not an exaggeration. I have subjected these containers to significant jostling and even inverted them in testing scenarios, and in every instance, the blue polyethylene closure held firm. This level of security is paramount for anyone handling potentially hazardous or valuable samples. The 90cc volume is perfectly suited for most standard field sample requirements, making it versatile without being overly bulky.

A significant strength is the predictability of its performance. There are no hidden quirks or areas requiring special attention. You fill it, you screw on the cap, and you trust it. This reliability is a key differentiator. If there’s an area for improvement, it’s subjective; while the closure is incredibly secure, it requires a firm twist, which might be a minor point for individuals with very limited hand strength, though it’s a necessary trade-off for the leak-proof guarantee. Overall, it not only meets but often exceeds the basic expectations for a specimen container.

Design & Ergonomics

The design of the Medegen Medical Vwr Container Speci 90CC CS200 PC4090-200S Vwr Container Speci 90CC CS200, Case of 200 is a testament to functional minimalism. The polypropylene material offers a good balance of rigidity and resilience, making it comfortable to hold without feeling flimsy. Its opaque nature, while not a specific feature listed, helps protect light-sensitive samples from degradation.

The overall weight of each container is negligible, making it easy to carry a large number in the field without adding significant bulk or heft to your gear. The threaded neck is well-formed, allowing the blue polyethylene closure to mate cleanly and securely with each use. There is no complex learning curve here; the design is intuitive and straightforward, making it instantly usable by anyone familiar with basic screw-top containers.

The ergonomic focus is clearly on practicality and ease of use. The slightly wider mouth compared to some smaller containers makes filling easier, especially when working with less precise tools in outdoor environments. The texture of the polypropylene provides a decent grip, even if your hands are slightly damp from fieldwork. It’s a design that prioritizes function over aesthetics, which is exactly what you want in this type of equipment.

Durability & Maintenance

The durability of the Medegen Medical Vwr Container Speci 90CC CS200 PC4090-200S Vwr Container Speci 90CC CS200, Case of 200 is exceptional, largely thanks to the break-resistant polypropylene construction. I’ve used them extensively, and they show no signs of the stress cracks or hazing that can appear on lesser plastics after repeated use or exposure to temperature fluctuations. The threads on both the container and the closure remain sharp and functional, ensuring a secure seal over time.

Maintenance is virtually non-existent for their primary intended use as single-use sterile containers. If repurposed for non-critical applications, they are easily washed with standard laboratory detergents and rinsed thoroughly. The smooth interior surfaces prevent significant residue buildup, making them easy to clean. Their ability to withstand typical cleaning agents and temperatures adds to their long-term viability even outside their sterile, single-use role.

Accessories and Customization Options

The Medegen Medical Vwr Container Speci 90CC CS200 PC4090-200S Vwr Container Speci 90CC CS200, Case of 200 comes as a complete, self-contained unit. The primary “accessory” is the integral blue polyethylene closure, which is essential for its functionality and is not a separate piece to be lost or replaced. The product is typically sold as a standalone item, with the Case of 200 being the primary bulk offering.

As these are disposable laboratory consumables, customization options in the traditional sense (like adding optics or changing grips) are not applicable. However, their standardization and compatibility with common laboratory practices are key. They are designed to integrate seamlessly into existing workflows, compatible with most standard sample handling equipment and analysis protocols. While there isn’t a need for aftermarket modifications, the consistent dimensions and reliable sealing mean they work universally within their intended application.
