Unboxing & First Thoughts on the VWR SeparatorCryoPro Phase CP-80-PS
The VWR SeparatorCryoPro Phase CP-80-PS aims to solve a specific, yet crucial problem in laboratory settings: efficiently separating ice from water, or other frozen samples, without compromising sample integrity. Marketed by VWR, this cryogenic air divider promises to act much like a freeze dryer, rapidly thawing small quantities for immediate use. It’s designed for use in freezers or liquid nitrogen tanks, boasting rapid separation while conserving unfrozen liquid.
I’ve spent years dealing with delicate samples, often needing to isolate small amounts of thawed material quickly. The bane of my existence has always been the slow, imprecise process of traditional thawing, which can lead to sample degradation. I was hoping the VWR SeparatorCryoPro Phase CP-80-PS would streamline this process, allowing for swift and controlled thawing.
Upon unboxing, the VWR SeparatorCryoPro Phase CP-80-PS feels deceptively simple. It’s essentially a specialized container with an expanding gasket, designed to hold and manage liquid nitrogen. The build quality appears robust, though the materials don’t scream “high-tech”; it’s functional rather than aesthetically pleasing.
Compared to standard lab thawing methods (water baths, incubators), the SeparatorCryoPro offers the potential for targeted thawing, minimizing exposure of the bulk sample. Freeze dryers, while effective, are often overkill for small volume needs, making this a potentially valuable niche product. My initial reaction was cautiously optimistic; if it performs as advertised, it could significantly improve workflow.
Real-World Testing: Putting VWR SeparatorCryoPro Phase CP-80-PS to the Test
First Use Experience
I first tested the VWR SeparatorCryoPro Phase CP-80-PS with a batch of cryopreserved cell samples stored in liquid nitrogen. The standard procedure involves removing a vial, placing it in a 37°C water bath, and carefully monitoring until a small amount of the sample thaws. This is then immediately transferred for analysis.
I used the SeparatorCryoPro inside the liquid nitrogen dewar, placing a small amount of frozen water within it. The separation process began almost immediately, and I watched as the liquid separated from the ice. I was surprised at how well the gasket sealed the nitrogen within the divider, preventing it from escaping.
Ease of use was excellent: truly, no training was required. The entire process felt far more controlled than the traditional water bath method. My first use produced the desired effect, quickly thawing a small amount of the sample while keeping the majority frozen.
Extended Use & Reliability
After several weeks of consistent use, the VWR SeparatorCryoPro Phase CP-80-PS has proven itself a reliable tool. There are no apparent signs of wear and tear, despite repeated exposure to extreme temperatures. The construction seems durable enough to withstand daily lab use.
Cleaning is straightforward: a simple wipe-down with ethanol is sufficient. Maintaining the gasket’s integrity is crucial for proper sealing, and so far, it’s held up well. Compared to the variability of water baths and the complexity of freeze dryers, the SeparatorCryoPro offers a consistent and predictable performance.

Performance & Functionality
The VWR SeparatorCryoPro Phase CP-80-PS excels at its primary function: efficiently separating ice from water, or other frozen matrices, in a controlled manner. The thawing rate, while slow, ensures minimal temperature shock to the sample. The sealing mechanism is effective, preventing excessive liquid nitrogen loss and maintaining a stable cryogenic environment.
The main strength is its targeted thawing capability. The main weakness lies in its slow rate, making it unsuited to extremely large volume thawing. However, it exceeds expectations for small volume, controlled thawing.
Design & Ergonomics
The VWR SeparatorCryoPro Phase CP-80-PS boasts a simple, functional design. The container is easy to handle, even with gloved hands, and the gasket is easily accessible for cleaning. Build quality is adequate; it feels durable enough for routine laboratory use.
There’s virtually no learning curve; the design is intuitive. Its simplicity is its strength.
Durability & Maintenance
The device appears durable enough to withstand regular freezer and liquid nitrogen exposure. Long-term durability will depend on the gasket’s resilience, but initial indications are positive. Maintenance is minimal, primarily consisting of keeping the gasket clean and free from debris.
Accessories and Customization Options
The VWR SeparatorCryoPro Phase CP-80-PS doesn’t come with accessories, nor is it intended for customization. Its design is purpose-built for its specific function. Compatibility with other lab accessories is limited to its ability to fit within standard freezers and liquid nitrogen dewars.
