12ml (131mm) vs 10ml (121mm) — How to Choose

Same ten-slot PP shell family, different cavity depth. This page is the 12ml edition: ten molded cavities cut to 131mm for 12ml-class vials. If your vials are the 10ml size (up to 121mm), choose the 10ml / 121mm edition. Always measure the vial's real length including the cap — when in doubt, size up to 131mm.

Household Skincare Fridges — layered batch storage keeps bulk peptide samples organized without wasting a shelf. Medical Beauty Salons — high-volume lyophilized powders sorted behind one clear lid, checkable without opening. Research Laboratories — bio-reagent specimens held upright in ten fixed cavities, ready for cold-room shelving.

Built from eco-friendly, BPA-free food-grade PP, the shell stays rigid and optically clear even after months of low-temperature refrigeration — no fogging, no warping, and no harmful chemical precipitation that could compromise activity-sensitive freeze-dried ingredients. The two-piece snap closure pops open in seconds for quick sample checks and seals tight again, locking dust and moisture outside while isolating all ten vials from external pollutants and physical impact.

Before any product ships, it passes our 6-station in-house QC: drop testing, compression testing, tensile strength, torque (for screw-cap accessories), climate cycling, and final dimensional inspection. See how we test every batch →/about-us.html

Send Inquiry (24h reply) → Free Design & Structural Proof (48h) → Sample (5–7 days) → Confirm & 30% Deposit → Production with QC (15–25 days) → Ship & After-support. As a professional direct manufacturer, we provide full OEM customization for bulk wholesale orders — custom UV brand logo printing, optional colored plastic shells and slight mold dimension adjustments for private-label packaging serving peptide factories, cosmetic brands and medical research institutes. All edges are finely polished without sharp burrs, ensuring safe repeated loading and unloading of glass vials for long-term cyclic use. Mixed orders with the 121mm edition are fine — both share one production run, so slot-count and size mixes don't break MOQ 20.
