16mm Base Freezer Vials - ISO 9001 Certified for Laboratory Storage

What Are 16mm Base Freezer Vials & Why Do Labs Need Them?

If you've ever spent time in a lab, you know how much care goes into collecting and preserving samples. A single mistake in storage can ruin weeks or months of work, not to mention the cost of lost data and materials. That's where 16mm base freezer vials come in—small but mighty containers built to protect your most sensitive samples from the harshest conditions, including the ultra-cold temperatures of liquid nitrogen.

These vials aren't just any plastic containers. Their 16mm base size is a standard in lab storage, fitting perfectly into most freezer racks and boxes to maximize space efficiency. But what really makes them indispensable is their ability to keep samples safe from contamination, leakage, and temperature swings. As a cryogenic tubes manufacturer with years of expertise, we've designed our 16mm base freezer vials to address every pain point lab professionals face when storing samples.

Let's take a deep dive into what makes these vials a game-changer for labs across the globe. From their durable material to their airtight seals, every feature is crafted with sample integrity at the forefront.

Key Features of Our 16mm Base Freezer Vials

When it comes to sample storage, there's no room for compromise. Our 16mm base freezer vials are packed with features that ensure your samples stay viable and uncontaminated, no matter how long they're stored. Here's a closer look at each one:

1. Medical-Grade Polypropylene (PP) Material

Every vial is made from high-purity medical-grade PP. This material is chosen for three key reasons: first, it's resistant to most chemicals, so it won't react with your biological or pharmaceutical samples. Second, it's incredibly durable—able to withstand rapid temperature changes without cracking or breaking. Third, it's autoclavable at 121°C, making it reusable for non-sensitive applications if needed.

Unlike cheaper plastics that can leach harmful substances into samples, our PP is tested to ensure it's free from toxins and contaminants. This is critical for labs working on clinical trials or drug development, where even the smallest impurity can skew results.

2. Leak-Proof Seal with Silicone Gasket

Leakage is one of the biggest risks in sample storage. A single leak can not only ruin your sample but also contaminate other samples in the freezer. Our vials feature a leak-proof cryotube with silicone gasket that creates an airtight seal when the cap is tightened. The silicone gasket conforms perfectly to the vial's opening, preventing any liquid or vapor from escaping—even when submerged in liquid nitrogen.

We test every batch of vials for leaks using a pressure test: each vial is filled with air, sealed, and submerged in water to check for bubbles. Any vial that fails this test is discarded immediately, so you can trust that every vial you receive is 100% leak-proof.

3. Sterile & Pyrogen-Free

Contamination is a lab's worst nightmare. That's why our vials are sterile cryo vials for liquid nitrogen , sterilized using either ethylene oxide (EO) or gamma radiation—two methods that are proven to kill all microorganisms, including bacteria, fungi, and viruses. This means you can use the vials straight out of the box without any additional sterilization, saving you time and reducing the risk of cross-contamination.

Additionally, our vials are pyrogen-free. Pyrogens are substances that can cause fever in humans, and they're a major concern in clinical and pharmaceutical labs. By eliminating pyrogens, we ensure that your samples are safe for use in sensitive applications like vaccine development or patient testing.

4. -196°C Temperature Resistance

Liquid nitrogen storage is the gold standard for long-term sample preservation because it keeps samples at -196°C, slowing down molecular activity to almost zero. But not all containers can handle this extreme cold. Our vials are specifically designed as -196°C cryogenic storage tubes , so you can store your samples in liquid nitrogen without worrying about the vials cracking or breaking.

This temperature resistance is crucial for preserving the viability of sensitive samples like stem cells, sperm, embryos, or nucleic acids (DNA/RNA). These samples need to be stored at ultra-low temperatures to maintain their structure and function, and our vials are up to the task.

5. Easy Labeling & Tracking

Keeping track of hundreds or thousands of samples can be a logistical nightmare. Our vials come with a large, frosted writable surface that allows you to label each vial with important information like sample ID, date of collection, experiment name, and researcher initials. The frosted surface ensures that your labels won't smudge or fade, even when exposed to freezer frost or alcohol-based cleaners.

For labs that need more advanced tracking, we also offer barcoded vials. These vials have a unique barcode printed on the surface, which can be scanned into a lab management system to quickly retrieve sample information. This reduces the risk of human error and makes it easier to manage large sample collections.

6. DNase/RNase Free

If you work with nucleic acids (DNA or RNA), you know how destructive DNase and RNase enzymes can be. These enzymes break down nucleic acids, rendering your samples useless for downstream applications like PCR or sequencing. Our vials are DNase/RNase free, meaning they don't contain any of these enzymes. This ensures that your DNA and RNA samples remain intact and usable for years to come.

We get a lot of questions about our vials. Here are some of the most common ones:

How to Use 16mm Base Freezer Vials Properly

To get the most out of your vials, it's important to use them correctly. Here are some tips to ensure your samples stay safe:

1. Preparing the Vial

Before using the vial, make sure it's at room temperature. If you're using a sterile vial, don't open it until you're ready to add the sample. This prevents contamination from the air or your hands.

2. Adding the Sample

Use a sterile pipette to add the sample to the vial. Don't overfill the vial—leave at least 10% headspace to prevent expansion during freezing. For liquid samples, fill the vial to about 80% capacity.

3. Sealing the Vial

Tighten the cap firmly to ensure a leak-proof seal. Make sure the silicone gasket is properly seated in the cap. If you're using the vial for liquid nitrogen storage, double-check the seal to prevent leakage.

4. Labeling the Vial

Label the vial immediately after adding the sample. Use a permanent marker to write on the frosted surface. Include important information like sample ID, date of collection, experiment name, and researcher initials. If you're using barcoded vials, scan the barcode into your lab management system.

5. Storing the Vial

Place the vial in a freezer rack or box. For liquid nitrogen storage, lower the vial slowly into the LN2 tank to prevent thermal shock. Avoid dropping the vial into the tank, as this can cause it to crack.

6. Retrieving the Vial

When retrieving the vial from liquid nitrogen, use tongs to handle it. Allow the vial to thaw slowly at room temperature or in a water bath (37°C for biological samples). Don't open the vial until it's fully thawed, as this can cause condensation to form inside and contaminate the sample.
