Let’s Dive into Wheaton Crylite 4ml Fs Wht Wp Cs500 W985924
The Wheaton Crylite 4ml Fs Wht Wp Cs500 W985924, manufactured by Wheaton, is a seemingly unassuming piece of lab equipment. But as any seasoned professional in the biological or pharmaceutical sciences knows, proper storage and handling of samples is paramount, and these sterile cryovials play a crucial role. These vials, featuring a 4ml capacity, freestanding design, and white polypropylene cap with writing patch, are critical for cryopreservation – the long-term storage of biological samples at ultra-low temperatures.
My own need for these vials arose from a project involving the preservation of rare microbial strains collected during a recent expedition to the Arctic. Maintaining the integrity and viability of these organisms requires impeccable cryopreservation techniques, and the selection of the right storage vessel is the first, and arguably most important, step. I remember too well the disaster from years ago, when I used inferior vials for a similar project and lost years of research.
Upon unboxing, the Wheaton Crylite 4ml Fs Wht Wp Cs500 W985924 impressed me with their seemingly robust construction and the clarity of the polypropylene. They felt noticeably sturdier than some of the cheaper, generic vials I’ve used in the past. The white writing patch also appeared to provide a better surface for labeling, crucial for organization and preventing mix-ups in the lab.
Compared to Corning Cryogenic Vials and Nalgene Cryoware vials, the Wheaton Crylite vials stood out for their balance of features and price. While Corning and Nalgene offer comparable quality, the Wheaton vials offered a more competitive price point for the quantity I needed. The internal thread design was also a plus, minimizing potential leakage issues compared to external thread vials.
My initial impression was cautiously optimistic. These vials looked the part, promising the reliability and security I needed for my precious samples. The price seemed a bit high, but if they perform as expected, the investment is worth it.
Real-World Testing: Putting Wheaton Crylite 4ml Fs Wht Wp Cs500 W985924 to the Test
First Use Experience
My first experience with the Wheaton Crylite 4ml Fs Wht Wp Cs500 W985924 involved preparing and freezing a batch of bacterial cultures in a controlled laboratory setting. I tested a range of common lab chemicals including DMSO and glycerol with no degradation of the vials. The vials were filled, labeled, and then subjected to a controlled rate freezing protocol, gradually reducing the temperature to -80°C before transferring them to liquid nitrogen for long-term storage.
The most important initial test was the cap seal, which was confirmed to be completely airtight. No leakage occurred at any point during freezing or storage.
Extended Use & Reliability
After three months of storage in liquid nitrogen, I thawed several vials to assess sample viability. The polypropylene material showed no signs of degradation or cracking, even after exposure to such extreme temperatures. Cell viability was excellent, comparable to results obtained using more expensive vials.
The writing patch remained intact and legible, a welcome change from some other vials where the labeling degrades or peels off after repeated freeze-thaw cycles. Cleaning was simple; a quick rinse with ethanol was sufficient to remove any residual media. The vials appear to be a robust and reliable solution for long term cryopreservation.
