2ml Internal Thread Cryo Vials – Medical Grade Containers for Sample Storage

When you're storing sensitive biological samples—like cell cultures, DNA extracts, or vaccine specimens—you can't cut corners on the containers you use. That's where 2ml internal thread cryo vials come in: small, robust, and designed to keep your samples safe even at ultra-low temperatures down to -196°C (liquid nitrogen level). But not all cryo vials are created equal. If you're looking for a reliable cryogenic tubes manufacturer that delivers medical grade quality, you've come to the right place.

Let's be honest: Lab work is stressful enough without worrying about whether your samples are safe. You spend hours (or even days) collecting and preparing samples—so why risk losing them to a cheap, faulty vial? Our cryo vials are built to take the stress out of sample storage. They're made with the highest quality materials, tested rigorously, and designed to meet the strictest standards.

We use only medical-grade PP for our cryo vials. Why PP? Because it's one of the most durable plastics out there. It's resistant to chemicals (like ethanol, methanol, and DMSO), doesn't become brittle at low temperatures, and won't leach any harmful substances into your samples. Unlike some cheaper manufacturers who use generic plastic, our PP is sourced from top suppliers and comes with a certificate of analysis (COA) to prove its quality.

We also test every batch of PP for purity. We check for heavy metals (like lead and mercury), phthalates, and BPA—all of which are strictly forbidden in medical grade plastic bottles. This ensures that your samples stay pure and uncontaminated.

The internal thread design is a game-changer. Unlike external threads (which stick out and can catch on things), internal threads are inside the vial neck. This means two things: first, the cap fits more tightly, creating a better seal. Second, the threads are less exposed to dust, debris, or other contaminants. If you're working in a lab where cross-contamination is a big concern, this design is a must-have.

We've done side-by-side tests with external thread vials. Our internal thread vials had 90% fewer cases of cross-contamination when stored in a shared rack. That's a huge difference when you're dealing with sensitive samples.

Each cap comes with a silicone gasket that's custom-made to fit our vials. We test every batch of gaskets to make sure they're elastic enough to create a tight seal, even after repeated use. We've done ｄｒｏｐ tests (from 1 meter high) and submergence tests (in liquid nitrogen) to confirm that our vials don't leak. No more worrying about losing your precious samples because of a faulty seal!

The silicone gasket is also resistant to cold and chemicals. It won't harden at -196°C or break down when exposed to solvents. This means it will keep working for as long as you need it to.

Our vials have clear volume markings (0.5ml, 1ml,1.5ml,2ml) printed on the side. The ink we use is specially formulated to resist cold and solvents—so even if you wipe the vial with ethanol or freeze it for years, the markings won't fade. This makes it easy to track how much sample you have, which is critical for experiments and record-keeping.

We also offer custom markings. If you need to add your lab's name, sample ID, or any other info, we can print it on the vial. The markings are done with a high-quality printer that ensures they're legible and long-lasting.

We offer two sterilization options for our vials: ethylene oxide (EO) and gamma irradiation. Both methods are validated to kill 99.99% of microorganisms. EO sterilization is great for heat-sensitive materials, and it leaves no residue (after a short aeration period). Gamma irradiation is faster and more effective for larger batches.

Every sterile order comes with a certificate of sterilization. This certificate includes the batch number, sterilization method, date, and a signature from our quality control manager. You can use this certificate to validate your processes and comply with regulatory requirements.

These vials are built to handle the coldest conditions. We've tested them by storing them in liquid nitrogen (-196°C) for 5 years—yes, 5 years!—and they still look and perform like new. We also do freeze-thaw cycles: freezing the vials to -196°C, thawing them to room temperature, and repeating the process 100 times. The vials don't crack, warp, or lose their seal.

This level of durability is crucial for long-term storage. If you're storing samples for a clinical trial or a long-term research project, you need to know that your vials will hold up over time. Our vials do exactly that.

You might be wondering: Why pay extra for medical grade vials? Can't I just use any plastic vial? The answer is simple: Medical grade vials are designed to keep your samples safe. They meet strict standards that generic vials don't.

We're an iso9001 certified packaging factory. This means we follow strict quality management processes. Every step from raw material sourcing to final packaging is documented and audited. We have a team of quality control experts who check every batch of vials to make sure they meet our standards.

ISO9001 also requires us to have a corrective action process. If a customer reports a problem with our vials, we investigate the root cause (like a faulty mold or a bad batch of gasket), fix it, and prevent it from happening again. This ensures that our vials are always of the highest quality.

Our workshop is dust-free and GMP compliant. What does that mean? GMP (Good Manufacturing Practices) is a set of guidelines that ensure products are made in a clean, safe environment. Our workshop has HEPA filters in the ceiling that clean the air every 10 minutes. We also require all employees to change into sterile gowns, gloves, and masks before entering the workshop.

Even the tools we use (like tweezers and racks) are sterilized daily. This ensures that our vials are free from dust, bacteria, and other contaminants. If you're working in a clinical setting or a lab that requires sterile products, this is non-negotiable.

Medical grade vials are designed to preserve sample integrity. Our vials won't leach any harmful substances into your samples. We've tested them with a wide range of samples—from blood and urine to cell cultures and DNA—and found no signs of contamination.

This is critical for research. If your sample is contaminated, your results will be inaccurate. You could spend months working on a project only to find out that your data is useless because of a faulty vial. Our vials prevent that from happening.

Our cryo vials are used in a wide range of industries. Here are some of the most common applications:

Biobanks store human or animal tissue samples, blood samples, or stem cells for future research or treatment. Our vials are perfect for this because they're durable and leak-proof. They can keep samples safe for decades, which is essential for long-term biobanking projects.

For example, a biobank that stores stem cells for cancer treatment uses our vials. The stem cells are stored in liquid nitrogen, and our vials keep them viable for years. When a patient needs a stem cell transplant, the biobank can retrieve the cells and use them immediately.

Pharmaceutical companies use our vials to store drug candidates, vaccine batches, and cell lines. Our vials are sterile and meet all the regulatory requirements for clinical trials. They're also resistant to chemicals, which is important for storing drug samples.

A major pharmaceutical company uses our vials to store cell lines that are treated with a new cancer drug. The vials keep the cell lines safe so researchers can study their response over time. This helps the company develop more effective drugs.

IVF clinics store embryos and sperm in cryo vials. The vials need to be completely sterile and leak-proof to ensure the embryos stay viable. Our vials meet all the clinical standards required for IVF. They're also easy to handle, which is important for clinic staff.

An IVF clinic in Europe uses our vials to store embryos. The clinic has reported a 95% success rate with our vials—meaning 95% of the embryos stay viable after thawing. This is a huge improvement over the generic vials they used before.

Academic labs use our vials for a wide range of experiments. From cell culture to DNA extraction, our vials are reliable and easy to use. They're also affordable, which is important for labs with tight budgets.

A university lab uses our vials to store DNA samples from endangered species. The vials keep the DNA intact so researchers can study the species and develop conservation plans.

We know that every lab has unique needs. That's why we offer a wide range of customization options. Whether you need custom markings, custom colors, or even custom mold design for plastic bottles, we've got you covered.

We can print your lab's logo, name, or sample ID on the vials. We offer two methods: screen printing and laser engraving. Laser engraving is more durable (it etches the logo into the plastic), while screen printing is better for colorful logos. We can also add barcodes or QR codes to the vials so you can track them using a scanner.

For example, a lab that studies climate change uses our vials with QR codes. Each QR code links to a database that contains information about the sample (like where it was collected and when). This makes it easy to track thousands of samples.

We can make vials in any color you want. Amber vials are great for light-sensitive samples (like vitamins or essential oils). Blue or green vials are perfect for distinguishing between different types of samples. We can match any Pantone color code—just let us know what you need.

If you need a vial with a unique design (like a larger opening or a different capacity), we can create a custom mold for you. Our team of mold designers uses 3D modeling software to design the mold. We then make a prototype for testing before mass production. This ensures that the mold is perfect for your needs.

A research lab needed a vial with a larger opening to make it easier to transfer cell cultures. We designed a custom mold for them, and the prototype was ready in just 2 weeks. The lab was thrilled with the result.
