DNase/RNase-Free Cryo Tubes Manufacturer - GMP & ISO Certified Since 2015

Let's be honest—when you're storing cells, DNA samples, or vaccine vials in liquid nitrogen, the last thing you want to worry about is whether your cryo tubes will hold up. A leak, a contamination, or a tube that cracks under extreme cold can ruin months of hard work. That's why choosing the right DNase/RNase-free cryo tubes manufacturer isn't just a purchase—it's an investment in your research's success.

Since 2015, we've been that trusted partner for labs, biotech firms, and pharmaceutical companies around the world. As a GMP and ISO 9001 certified manufacturer, we don't cut corners when it comes to quality. Our DNase/RNase-free cryo tubes are designed to keep your samples safe, intact, and ready for use whenever you need them. But we're more than just a cryo tube maker—we're a full-service pharmaceutical packaging manufacturer, offering everything from HDPE pill bottles to custom mold design for plastic bottles. Let's dive in and see why so many brands rely on us.

When it comes to cryo storage, every detail matters. Our tubes are built to address all the pain points labs and pharma companies face—from contamination risks to leaky designs. Here's what sets us apart:

GMP & ISO 9001 Certified: Quality You Can Trust
Here's what our GMP certification means for you: every single cryo tube we make is produced in a dust-free, sterile workshop. We follow strict hygiene protocols—from the moment raw materials enter our factory to the second finished products leave. Our team wears full protective gear (gloves, masks, gowns) to prevent any contamination during manufacturing. Our ISO 9001 certification ensures that our quality management system is consistent and reliable, so you get the same high-quality tubes every time you order. No surprises, no defects—just peace of mind.

DNase/RNase-Free Assurance: Protect Your Samples
Contamination with DNase or RNase is a lab's worst nightmare. These enzymes can break down DNA and RNA samples, rendering them useless. That's why we go above and beyond to ensure our cryo tubes are completely free of these enzymes. Our process includes:

• Ultrasonic cleaning with purified water to remove all traces of impurities.
• Sterile drying in a HEPA-filtered environment.
• PCR testing of every batch to confirm no DNase or RNase is present.

You can rest easy knowing your samples are safe from enzymatic degradation.

Leak-Proof Design: No More Lost Samples
There's nothing more frustrating than opening a liquid nitrogen tank and finding a leaky cryo tube. Our tubes are designed with a silicone gasket that creates an airtight seal, even at -196°C. We offer both internal and external thread options:

• Internal threads: Prevent cross-contamination by keeping the thread area inside the tube (away from samples).
• External threads: Easy to open and close, ideal for frequent use.

Every tube undergoes a rigorous leak test—we submerge them in water and apply pressure to ensure no liquid gets in.

Variety of Sizes to Fit Your Needs
We know labs have different storage requirements. That's why we offer a wide range of cryo tube sizes. Here's a breakdown of our most popular options:

Durable Material: Polypropylene (PP)
We use only high-quality polypropylene (PP) for our cryo tubes. PP is the ideal material for cryo storage because:

• It's resistant to extreme temperatures (from -196°C to 121°C).
• It's non-reactive, so it won't interact with your samples.
• It's durable and won't crack under pressure.

Unlike glass tubes, PP tubes are shatterproof—so you don't have to worry about broken tubes in your liquid nitrogen tank.

Making a high-quality cryo tube isn't just about molding plastic—it's a science. Our process is designed to ensure every tube meets our strict standards. Here's a step-by-step look at how we make our tubes:

Step 1: Design & Material Selection
We start by selecting the right material (PP) for the tube. Then, our engineers design the tube using 3D modeling software. We consider factors like thread type, gasket design, and size to ensure the tube is functional and easy to use. If you need a custom design, our custom mold design for plastic bottles service can help you create a tube that fits your exact needs.

Step 2: Injection Molding
We use high-precision injection molding machines to create the tubes. The PP material is melted and injected into a mold, which is cooled to form the tube shape. Our machines are calibrated to ensure every tube has the same dimensions—no variations, no defects.

Step 3: Cleaning & Sterilization
After molding, the tubes are sent to our cleaning department. They undergo ultrasonic cleaning with purified water to remove all traces of impurities. Then, they are dried in a HEPA-filtered environment to prevent contamination. Finally, the tubes are sterilized using either EO (ethylene oxide) or gamma radiation—whichever is best for your needs.

Step 4: Quality Control
Quality control is at the heart of everything we do. Every batch of tubes undergoes a series of tests:

• Leak test: Submerge tubes in water and apply pressure to check for leaks.
• Enzyme test: PCR testing to confirm no DNase or RNase is present.
• Dimensional test: Use calipers to check the size and shape of the tubes.
• Sterility test: Incubate tubes to ensure no bacteria or fungi are present.

Only batches that pass all these tests are shipped to our clients.

As a leading pharmaceutical packaging manufacturer, we offer a wide range of products to meet the needs of labs and pharma companies. Here are some of our most popular products:

HDPE Pill Bottles: Safe & Reliable
We are a trusted hdpe pill bottles supplier, offering a variety of sizes (60ml,100ml,225ml,500ml) for vitamins, meds, and supplements. Our bottles are:

• Child-resistant (optional) to prevent accidental ingestion.
• Tamper-evident to ensure product safety.
• Made from medical-grade HDPE plastic.

Whether you need small sample bottles or large bulk bottles, we've got you covered.
