Real-World Testing: Putting VWRCryoPro Liquid Dewars, L Series L-50-WD Accessories to the Test
First Use Experience
Our initial testing took place in our biopharmaceutical research lab, where liquid nitrogen is crucial for preserving cell lines and biological samples. The dewar was used for both short-term storage during experiments and long-term cryopreservation. It was immediately evident that the design was centered around user safety and ease of dispensing.
The VWRCryoPro Liquid Dewars, L Series L-50-WD Accessories performed consistently well, even under varying ambient temperature conditions. We tested it in controlled climate rooms and also during brief periods in our loading dock with ambient temperature ranging from 60F to 85F with no significant change in liquid nitrogen consumption rate, even with frequent access. This is thanks to vacuum insulation technology.
The integrated handles made it surprisingly easy to move around the lab despite the potential weight of a partially filled dewar. The accessories, particularly the transfer hose (purchased separately), were intuitive to connect and use, reducing the risk of spills or accidental exposure. There was a slight learning curve in optimizing the dispensing rate, but that was quickly overcome with a few practice runs.
The first use revealed one minor area for improvement. While the handles are sturdy, a more ergonomic design could enhance comfort during longer transport across the lab. We did not notice this issue until the dewar was over half full, which added to the weight.
Extended Use & Reliability
After several months of continuous use, the VWRCryoPro Liquid Dewars, L Series L-50-WD Accessories continues to perform reliably. The dewar’s insulation maintains liquid nitrogen temperatures consistently, minimizing losses due to evaporation. This is crucial for our long-term storage needs.
Durability has proven to be a strong suit. The stainless-steel exterior shows no signs of corrosion or degradation despite exposure to occasional spills and frequent handling. The vacuum insulation is still holding strong.
Maintenance involves periodic cleaning of the exterior and inspection of the dispensing valve. The stainless-steel construction makes cleaning simple. We just use standard lab cleaning solutions to wipe down the exterior.
Compared to our previous dewars, the VWRCryoPro Liquid Dewars, L Series L-50-WD Accessories offers superior temperature stability and a more user-friendly design. Its reliability has reduced the frequency of liquid nitrogen refills and minimized the risk of sample degradation due to temperature fluctuations. This dewar has outperformed all expectations.
Breaking Down the Features of VWRCryoPro Liquid Dewars, L Series L-50-WD Accessories
Specifications
- Liquid Nitrogen Capacity: Although the specific capacity for accessories is not directly applicable, the dewar itself, when paired with the accessories, can handle up to 50 liters of liquid nitrogen. This substantial capacity minimizes the need for frequent refills.
- Weight Empty: The empty weight specification is not provided for the accessories; however, the dewar’s weight is a critical factor for mobility and handling. Lighter dewars are generally easier to maneuver.
- Weight Full: The full weight is similarly unavailable for just the accessories. However, a full dewar’s weight dictates the need for adequate support and cautious handling.
- Neck Diameter: Neck diameter information is not provided with the accessory details, but this measurement influences the rate of evaporation. A narrower neck generally means less evaporation.
- Overall Height x Outside Diameter: Dimensions of accessories are not provided. The dewar’s height and diameter impact its footprint in the lab.
- VWR Catalog#: 55709-286. This is the definitive identifier for ordering and referencing this specific VWRCryoPro Liquid Dewars, L Series L-50-WD Accessories set.
These specifications are important because they dictate how the dewar integrates into the workflow and affects the safety and efficiency of liquid nitrogen handling. Proper capacity, manageable weight, and efficient insulation all contribute to a better user experience.
