We believe that great cryogenic tubes start with great conversations. Our process—from your initial idea to a finished product—isn't just about manufacturing; it's about collaboration. Here's how we turn your vision into a tangible solution:
1. Understanding Your Needs: Collaborative Consultation
Every project starts with a conversation. We'll sit down with you (virtually or in person) to understand the specifics of your application: What samples will you be storing? What volume do you need? Do you require special features like child-resistant caps (for pharmaceutical use) or calibrated markings? Even seemingly small details—like whether you need conical or round bottoms—matter, and we take the time to get them right.
One of our clients, a leading biotech firm, once approached us needing a custom 2ml cryogenic tube with a unique barcode placement for automated tracking. By listening closely to their workflow challenges, we designed a tube that integrated seamlessly with their existing systems—saving them hours of manual data entry each week.
2. Precision in Design: Custom 3D Modeling & Engineering
Once we understand your needs, our engineering team gets to work creating detailed 3D models using advanced CAD software. This isn't just about making a tube look good—it's about ensuring functionality, durability, and compatibility with your storage systems. We'll share these 3D drawings with you for feedback, making adjustments until the design aligns perfectly with your requirements.
For example, if you need a tube that fits into a specific cryo storage rack, we'll model the dimensions to ensure a snug, secure fit. If you're concerned about sample retrieval, we might adjust the cap design for easier opening at ultra-low temperatures—because frozen fingers shouldn't have to struggle with stubborn lids.
3. Bringing Designs to Life: Custom Mold Design & Development
With your approved 3D drawing in hand, we move to custom mold design—a critical step that determines the quality and consistency of the final product. Our in-house mold shop uses high-grade steel to create molds that can withstand the rigors of high-volume production while maintaining precision down to 0.01mm tolerances.
Unlike many manufacturers who outsource mold making, we keep this process in-house, giving us full control over quality and timelines. This means if we notice a potential issue during mold testing—like a slight imperfection that could affect the tube's seal—we can adjust immediately, rather than waiting for a third party.
4. Production Excellence: Manufacturing in Controlled Environments
Production takes place in our state-of-the-art, dust-free GMP compliant workshop. We use medical-grade polypropylene (PP) resin, selected for its exceptional cold resistance, chemical inertness, and ability to maintain structural integrity at -196°C. Our injection molding machines are equipped with real-time monitoring systems that track temperature, pressure, and cycle time, ensuring every tube is identical to the last.
But we don't stop at the tubes themselves. Caps and closures are just as critical—our leak-proof silicone gaskets are tested under extreme pressure to ensure they create a hermetic seal, even after repeated freeze-thaw cycles. We know that a tube is only as good as its cap, and we treat both with equal care.
5. Rigorous Testing: Quality Assurance at Every Stage
Before any product leaves our facility, it undergoes a battery of tests. We randomly ｓｅｌｅｃｔ samples for leak testing (submerging capped tubes in liquid nitrogen and checking for moisture ingress), temperature cycling (exposing tubes to -196°C and room temperature repeatedly to test durability), and sterility checks (ensuring our pre-sterilized options are free from contaminants).
We also test for less obvious factors, like how easy the cap is to open when frozen—a small detail that makes a big difference for researchers working with gloves in cold rooms. If a batch doesn't meet our standards, it doesn't ship. Simple as that.
