Custom DNase/RNase-Free Cryogenic Tubes - Meet Your Lab's Specific Requirements

If you've ever spent hours carefully preparing cell cultures or collecting precious biological samples, only to lose them to contamination or leakage during cryopreservation, you know how frustrating that can be. That's why choosing the right cryogenic tubes is non-negotiable for any lab working with sensitive materials. At our facility, we specialize in custom DNase/RNase-free cryogenic tubes designed to meet your lab's exact needs—whether you're storing cells for research, preserving vaccine samples, or managing a biobank. Let's dive into what makes our tubes stand out and how we can tailor them to your specific requirements.

First things first—our cryogenic tubes are 100% DNase/RNase-free. How do we ensure that? We use medical grade plastic bottles made from high-quality polypropylene (PP) that's inert and won't react with your samples. Then, each batch goes through a rigorous cleaning process using validated methods to eliminate any traces of enzymes that could degrade nucleic acids. No more worrying about your DNA or RNA samples getting ruined before you even start your experiments.

All our tubes are pre-sterilized using either EO or gamma irradiation—whichever fits your needs. This means they're ready to use right out of the box, saving you time and reducing the risk of cross-contamination in your lab. We know how important it is to keep your samples safe during storage and transport. Our cryotubes come with silicone gaskets that create an airtight seal, even at temperatures as low as -196°C (liquid nitrogen temperature). No more frozen leaks or sample loss—your materials stay intact, no matter how cold it gets.

We offer a range of sizes from 0.5ml to 5ml, with both internal and external thread options. Whether you need small vials for individual cell samples or larger tubes for bulk storage, we've got you covered. Our tubes are also designed to be easy to handle—with ergonomic caps that are easy to screw on and off, even when wearing gloves.

As a cryogenic tubes manufacturer, we understand that every lab has unique needs. That's why we offer a wide range of customization options to make sure our tubes fit your workflow perfectly. Let's break down what we can do:

1. Size & Capacity: Choose from 0.5ml,1.8ml,2ml,5ml—whatever your experiment requires. If you need a size that's not on this list, just let us know—we can create custom sizes for you.

2. Thread Type: Internal or external threads? We can make both, depending on your storage racks or equipment. Internal threads are great for preventing liquid nitrogen from entering the tube, while external threads are easier to handle with gloves.

3. Closure Design: Silicone gaskets for extra leak protection, or screw caps with tamper-evident seals? Let us know. We can also add child-resistant caps if you're handling sensitive materials like CBD or pharmaceutical samples.

4. Labeling & Identification: Need barcoded tubes for easy tracking? Or writable surfaces so you can mark samples by hand? We can add both. For labs that need unique identifiers, we even offer custom printing options on the tubes or caps—like your lab's logo or a specific code.

5. Custom Mold Design: If our standard tubes don't meet your needs, our team can handle custom mold design for plastic bottles (and tubes!). We support 3D design customization and even offer free test molds so you can see the final product before mass production. This is perfect for labs that have specific dimensions or features in mind—like a conical bottom for easier sample retrieval, a flat bottom for stable storage, or a unique cap design for better handling.

When you request a custom mold, our design team will first review your 3D files. We'll make suggestions to improve the design—like adding a reinforced cap to prevent cracking or adjusting the tube's thickness for better durability. Once you approve the design, we'll create a test mold. The test mold is used to produce a small batch of tubes, which we'll send to you for evaluation. You can check the dimensions, fit, and any custom features. If you need changes, we'll adjust the mold and send another sample. This iterative process ensures that the final product meets your exact requirements. Best of all, we offer free test molds so you don't have to worry about upfront costs.

When it comes to lab supplies, quality is everything. That's why we're proud to be an iso9001 certified packaging factory with a dust-free gmp compliant workshop. Let's talk about what these standards mean for you:

ISO9001 Certification: This certification ensures our manufacturing processes are consistent and meet international quality standards. Every step from raw material selection to final packaging is documented and monitored, so you get the same high-quality tubes every time. We regularly undergo audits to maintain our ISO9001 certification, so you can trust that our processes are up to date.

GMP Compliant Workshop: Our GMP-compliant workshop is a Class 100,000 cleanroom. That means the air contains no more than 100,000 particles per cubic foot (0.5 microns or larger). We use HEPA filters to purify the air, and all staff wear sterile gowns, gloves, and masks when entering the workshop. We also perform regular air quality tests to ensure that the cleanroom meets GMP standards. This level of cleanliness is essential for producing medical grade plastic bottles and tubes that are free of contamination.

Quality Control: Every batch of cryogenic tubes goes through multiple tests—leakage tests at -196°C, sterility checks, DNase/RNase-free validation, and more. We don't ship any product until it passes all our quality checks. Let's walk through our quality control process in detail:

1. Raw Material Inspection: We only use medical-grade PP plastic from trusted suppliers. Each batch of raw material is tested for purity and inertness before it's used. We also check for any contaminants that could affect the final product.

2. Mold Production: If you're using a custom mold, our team will create a test mold first. We'll send you a sample so you can check the dimensions and features. Once you approve, we move to mass production.

3. Manufacturing: Our GMP-compliant workshop ensures that all tubes are made in a clean environment. We use automated machines to reduce human contact, which lowers contamination risks. The machines are regularly calibrated to ensure that the tubes have consistent dimensions.

4. Cleaning & Sterilization: After production, tubes are cleaned to remove any debris, then sterilized using EO or gamma irradiation. We test each batch for sterility to make sure it meets our standards.

5. DNase/RNase-Free Validation: We use specialized kits to test for the presence of DNase and RNase. Only batches that are 100% free of these enzymes are shipped.

6. Leakage Test: We submerge tubes in liquid nitrogen for 24 hours to check for leaks. Any tubes that leak are discarded.

7. Final Packaging: Tubes are packaged in sterile, sealed bags to keep them clean during transport. The bags are labeled with batch numbers and expiration dates for easy tracking.

If you don't need custom tubes, our standard options are perfect for most labs. Here's a breakdown of our most popular standard tubes:

All our standard tubes are compatible with liquid nitrogen storage and meet our strict quality standards. They're also designed to fit into most standard cryo boxes and racks, making them easy to integrate into your existing workflow.

Our cryogenic tubes are used in a wide range of applications. Let's take a look at some of the most common use cases:

For cell freezing, the choice of cryogenic tube can affect cell viability. Our tubes are made from polypropylene, which is resistant to cryogenic temperatures and won't crack when frozen. The DNase/RNase-free environment ensures that the cells' nucleic acids remain intact, so you can perform PCR or other genetic tests without issues. Many of our clients use our 1.8ml internal thread tubes for cell freezing because they fit into most standard cryo boxes and racks. The screw cap with silicone gasket creates a tight seal, preventing liquid nitrogen from entering the tube and damaging the sample.

Cell storage is a critical part of many research projects. Our tubes are designed to keep cells viable for years. The sterile environment and leak-proof seal ensure that cells don't get contaminated, and the DNase/RNase-free feature keeps their genetic material intact. This is perfect for labs that are working on long-term research projects or building a cell bank.

Biobanks store thousands of samples for long-term research. Our barcoded cryogenic tubes make it easy to track each sample, reducing the risk of mix-ups. We also offer bulk orders, which is perfect for biobanks that need large quantities of tubes. Plus, our tubes are designed to withstand repeated freeze-thaw cycles, so samples stay safe for years.

Biobanks often need to store samples for decades. Our tubes are made from high-quality PP plastic that's resistant to degradation, so they won't break down over time. The DNase/RNase-free feature ensures that the samples' genetic material remains intact, which is essential for future research. We also offer custom labeling options, like barcodes or QR codes, to make sample tracking easier.

During the pandemic, vaccine storage became a critical issue. Our cryogenic tubes are used by pharmaceutical companies to store vaccine samples at ultra-low temperatures. The leak-proof seal and sterile design ensure that samples remain uncontaminated, which is essential for vaccine development and testing.

Vaccine samples are extremely sensitive. Our tubes are designed to keep them safe during storage and transport. The DNase/RNase-free environment ensures that the vaccine's genetic material (if it's an mRNA vaccine) remains intact. We also offer custom sizes for vaccine samples—like 0.5ml tubes for small batches or 5ml tubes for larger samples.

Fertility clinics rely on our tubes to store sperm and embryos. The DNase/RNase-free environment is crucial here, as any contamination could affect the viability of the samples. Our tubes are also designed to be easy to handle, which is important for clinics that need to retrieve samples quickly.

Sperm and embryo storage requires the highest level of quality. Our tubes are pre-sterilized and DNase/RNase-free, so you can trust that the samples are safe. We also offer custom sizes—like 1.8ml tubes for sperm storage or 2ml tubes for embryo storage. The screw caps with silicone gaskets create a tight seal, preventing liquid nitrogen from entering the tube.
