Custom Volume Non-Pyrogenic Sterile Cryotubes (0.5ml to 10ml) | Bulk Supply

When it comes to preserving life-saving samples, every detail matters. Whether you're storing rare cell lines in a research lab, safeguarding vaccine batches for clinical trials, or archiving biological materials for future breakthroughs, the containers you choose can make or break the integrity of your work. That's where we come in—we've spent years perfecting the art of creating cryotubes that don't just hold samples, but protect them like a trusted partner.

A Range That Fits Every Need: 0.5ml to 10ml, Designed for Real Labs

No two labs work the same, and we get that. That's why our cryotube lineup spans from compact 0.5ml vials up to robust 10ml containers, each tailored to specific storage scenarios. Let's break down what makes each size a go-to choice for researchers and medical professionals:

Each size is available with internal or external threading (your call!) and either conical or round bottoms—because we know some protocols require centrifugation compatibility, while others prioritize space efficiency. No more forcing a one-size-fits-all solution into your workflow.

What Makes Our Cryotubes Stand Out? The Details That Protect Your Work

Let's get technical—but in a way that matters for your daily work. Our cryotubes aren't just plastic containers; they're engineered to survive the harshest conditions while keeping your samples 100% secure. Here's what sets them apart:

• Non-Pyrogenic & Sterile: We test every batch to ensure zero endotoxins (less than 0.1 EU/ml) and guaranteed sterility via either EO gas or gamma irradiation. No surprises when you uncap a vial—just pure, uncontaminated samples ready for use.
• Leak-Proof Sealing: Ever had a freezer disaster with leaking tubes? We've eliminated that nightmare with silicone gaskets that form an airtight seal, even after repeated freeze-thaw cycles down to -196°C (yes, liquid nitrogen temperatures are no match for these).
• Medical-Grade Polypropylene: We only use USP Class VI PP material, which means it's resistant to cracking at extreme cold, won't leach chemicals into your samples, and stands up to harsh detergents during decontamination.
• Easy-to-Mark Surfaces: Tired of smudged labels or illegible handwriting after storage? Our tubes have a frosted writing area that takes permanent markers like a champ, plus optional barcode-ready surfaces for labs using tracking systems.
