Polypropylene (PP) is a thermoplastic polymer that's become the gold standard for cryogenic storage—and for good reason. Let's break down why PP is the ideal material for your cryo tubes:
First, PP is incredibly durable at ultra-low temperatures. Unlike glass or some other plastics, PP doesn't become brittle when frozen. This means it can handle the extreme cold of liquid nitrogen (-196°C) without cracking or shattering, even after repeated freeze-thaw cycles. For labs that need to thaw and refreeze samples multiple times, this is a game-changer.
Second, PP is chemically resistant. It won't react with acids, bases, or most organic solvents—so you don't have to worry about the tube leaching harmful substances into your samples. This is especially important for medical grade applications, like storing vaccine samples or fertility treatments, where purity is non-negotiable.
Third, PP is non-toxic and biocompatible. Our PP tubes are made from
medical grade plastic bottles material that meets FDA and EU regulations, so they're safe for use with biological samples. Whether you're storing human cells, animal tissue, or pharmaceutical compounds, you can trust that our tubes won't contaminate your work.
Fourth, PP is easy to customize. As a company that offers
custom mold design for plastic bottles, we can create PP cryo tubes in a wide range of sizes, shapes, and thread types to fit your specific needs. Need a tube with a unique volume? A special thread to fit your existing cryo boxes? Or even a custom logo printed on the side? We've got you covered.
Finally, PP is cost-effective. Compared to glass or other high-end plastics, PP is more affordable without sacrificing quality. This makes it a great choice for labs that need to buy tubes in bulk, or for startups that are looking to keep their costs down while still maintaining high standards.
PP cryo tubes are used in a ton of applications across different industries:
1. **Biobanking**: Biobanks store thousands of biological samples (like blood, tissue, or DNA) for research purposes. Our PP tubes are uniform in size, so they fit perfectly into standard cryo boxes, making storage organized and efficient. The barcoded option also helps biobanks track samples quickly and accurately, reducing the risk of human error.
2. **Fertility Clinics**: Fertility clinics rely on cryo tubes to store sperm, eggs, and embryos. Our 2ml PP tubes are ideal for this purpose—they're leak-proof, sterile, and have a writable surface so clinicians can label each sample with patient information.
3. **Pharmaceutical Companies**: Pharma firms use PP cryo tubes to store vaccine samples, drug candidates, and other sensitive compounds. Our tubes are pre-sterilized using ethylene oxide (EO) gas, which kills all bacteria, viruses, and fungi without leaving any residue.
4. **Lab Research**: Labs use PP cryo tubes for everything from storing cell lines to aliquoting reagents. Our 0.5ml and 1.8ml tubes are perfect for small samples, while our 5ml tubes are great for larger volumes like blood or tissue.
No matter what you're storing, our PP cryo tubes are designed to meet your needs. We understand that every sample is valuable, and we take pride in producing tubes that you can trust.
