3D CAD Design Service for Custom Cell Freezing Cryogenic Tubes

Every project starts with a conversation. We'll ask detailed questions to uncover what matters most to you: Are you storing large volumes or small aliquots? Do you need compatibility with specific labeling machines or storage racks? What temperature ranges will the tubes endure? Even seemingly small details—like whether the tube needs to be stackable or have a writing surface for manual labeling—shape the design. This phase ensures we're not just creating a "custom" tube, but one that's custom-fit to your unique workflow.

Armed with your requirements, our design team gets to work on the 3D CAD model. Using advanced software, we build a digital twin of the cryogenic tube, incorporating every detail: from the thickness of the walls (critical for withstanding thermal shock) to the threading of the cap (to ensure a leak-proof seal). We then run virtual simulations to test performance: How does the material react to rapid cooling? Will the cap stay secure during transport? Can the tube withstand repeated freezing and thawing cycles? This digital testing phase catches potential issues early, saving time and resources later.

We don't move forward until you're completely satisfied with the design. We'll share 3D renderings and simulation results, walking you through every feature and explaining how it addresses your needs. If something doesn't align—maybe the neck is too narrow for your pipettes, or the base isn't stable enough—we'll revise the model on the spot. This back-and-forth is key to getting it right. We've found that clients appreciate this transparency; it gives them confidence that the final product will work exactly as intended.

Once the design is approved, we move to mold manufacturing. Our in-house tooling team uses high-precision machinery to create molds that match the 3D CAD specifications down to the micron. But we don't stop there: We offer free mold testing to ensure everything works perfectly before full production. We'll produce a small batch of sample tubes, which you can test in your lab under real-world conditions. Check the fit, test the seal, run them through your storage protocols—only when you give the green light do we proceed to mass production. This step eliminates the risk of investing in large orders of tubes that don't meet your needs.

With the mold validated, we shift to full-scale manufacturing. Our production lines are equipped to handle both small batches (for pilot studies) and large orders (for commercial pharmaceutical production). Throughout the process, every tube undergoes rigorous quality checks: dimensional accuracy, leak testing at -196°C, and visual inspections for defects. As an ISO9001 certified packaging factory, we document every step, so you have complete traceability from raw material to finished product.
