Getting My Hands on the Wheaton Crylite 2ml Fs Pnk Cs500 W985865

The world of laboratory consumables can often feel mundane, filled with identical-looking vials and pipettes. However, every so often, a product emerges that, despite its seemingly simple function, stands out. The Wheaton Crylite 2ml Fs Pnk Cs500 W985865 is one such item, a set of 2ml cryogenic vials that immediately caught my eye due to its specific design and the substantial pack size. My research into reliable, long-term storage solutions for sensitive biological samples, particularly those requiring meticulous organization and easy visual identification, led me to this particular model. The promise of free-standing capability and a distinctive pink polypropylene cap suggested a thoughtful design aimed at practical lab work.

My usual go-to for cryovials often involved a standard white-capped model from a different supplier, which while functional, lacked the finer touches. I was considering other brands known for their cryopreservation products, but the bulk offering of 500 units at a competitive price point for the Wheaton Crylite 2ml Fs Pnk Cs500 W985865 was a significant draw. The idea of having such a large quantity of identical, yet easily distinguishable vials immediately appealed to my desire for streamlined lab processes. Upon arrival, the sheer volume of the case was impressive, hinting at the extended period it would supply my needs.

My initial impression was one of robust, no-nonsense construction. The polypropylene material felt durable, and the caps screwed on with a satisfying degree of resistance, suggesting a good seal. The free-standing base was a feature I was particularly keen to evaluate, as it promised to simplify handling when working with samples on a busy bench. This was a far cry from the flimsy, often difficult-to-handle vials I’d encountered previously.

First Use Experience

My first encounter with these vials was during a routine sample processing day. The scenario was standard: aliquotting patient samples into smaller volumes for long-term storage in a -80°C freezer. I placed a few of the Wheaton Crylite 2ml Fs Pnk Cs500 W985865 vials on the bench, and the free-standing feature immediately proved its worth. Unlike traditional conical-bottomed tubes that tend to tip over, these stood upright without any effort, making it incredibly easy to pipette into them without fear of contamination or spillage.

The pink polypropylene cap was a subtle but highly effective touch for sample identification. I was able to quickly differentiate between different sample types or batches at a glance, a small detail that significantly speeds up workflow, especially when dealing with numerous samples. There was no immediate learning curve; they functioned exactly as a cryovial should, but with enhanced usability. The initial surprise was how much of a difference these small design elements made to the mundane task of aliquoting.

Extended Use & Reliability

After several weeks of consistent use, incorporating hundreds of aliquots and countless freeze-thaw cycles, the performance of these vials has been consistently impressive. They have been subjected to repeated handling, vigorous vortexing, and the harsh environment of a -80°C freezer, yet they show no signs of degradation. I have yet to encounter any leaks or cracks, which is a testament to the polypropylene construction and the secure fit of the external thread caps.

Maintenance is virtually non-existent, as expected for disposable plastics. However, their clean manufacturing and the smooth interior surfaces make them easy to rinse if accidental spills occur before sealing. Compared to some cheaper alternatives I’ve used in the past that could become brittle or difficult to seal after prolonged freezing, these vials have maintained their integrity remarkably well. The consistent performance across the entire Cs500 pack has instilled confidence in their long-term reliability for critical sample preservation.

Breaking Down the Features of Wheaton Crylite 2ml Fs Pnk Cs500 W985865

Specifications

The Wheaton Crylite 2ml Fs Pnk Cs500 W985865 is a key piece of lab equipment designed for precise sample management. Its core specification is a 2ml capacity, which is ideal for creating smaller, manageable aliquots from larger stocks. The material is polypropylene, a common choice for cryogenic storage due to its excellent chemical resistance and low temperature performance.

A standout feature is its free-standing (Fs) design, meaning the base is shaped to allow the vial to remain upright on a flat surface. This contrasts with many standard vials that require a rack for stability. The vials also boast an external thread cap, which minimizes the risk of sample contamination from the inner threads.

The specific model designation includes Pnk Cs500, indicating the pink cap and that it comes in a bulk pack of 500 units. The catalog number 89125-504 and supplier number W985865 further identify this specific configuration. This combination of features makes it suitable for applications where organization, stability, and reliable sealing are paramount.

Performance & Functionality

In terms of its primary function, the Wheaton Crylite 2ml Fs Pnk Cs500 W985865 excels at securely storing samples at cryogenic temperatures. The external thread cap ensures a tight seal, minimizing evaporation and contamination risk, which is critical for preserving sample integrity over long periods. The 2ml volume is perfect for creating single-use aliquots, preventing multiple freeze-thaw cycles on the main sample stock.

The free-standing base is, without a doubt, its greatest functional advantage. It simplifies pipetting, sample labeling, and general handling on a crowded laboratory bench. I’ve also found the pink color of the cap to be surprisingly beneficial for quick visual identification and organization, especially when managing multiple projects or sample types simultaneously. This is a clear strength that enhances overall lab efficiency.

The only minor limitation I can identify is that, like most cryovials, they are intended for single use or limited reuse depending on the application and sterilization. While the material is robust, the expectation is for disposable use, which is standard for this type of product.

Design & Ergonomics

The design of these vials is both practical and user-friendly. The polypropylene material offers a good balance of durability and flexibility, ensuring they won’t crack under normal handling or freezing. The external thread design of the cap is smooth and easy to grip, allowing for confident tightening and loosening without cross-threading.

The free-standing base is ingeniously integrated, providing stable support without adding significant bulk. The clear markings on the vial body are easy to read, aiding in accurate volume assessment and labeling. Even after repeated handling and exposure to different temperatures, the finish remains intact, showing good quality control from Wheaton.

Durability & Maintenance

As disposable plastics, these vials are designed for single or limited reuse in specific laboratory protocols. Under standard cryogenic storage conditions (-80°C), I anticipate they will maintain their integrity for years. The polypropylene is inherently resistant to common lab solvents and biological fluids, preventing degradation of the material itself.

There is virtually no specific maintenance required beyond ensuring the cap is securely fastened before storage. For cleaning purposes, if a vial needs to be rinsed, the smooth interior surface is easy to wipe down or rinse out. I haven’t encountered any premature failures or signs of material fatigue, even after accidentally dropping a capped vial on a linoleum floor without it breaking.
