Laboratory Storage — four 10ml vials held separate in molded recessed slots, no mutual collision or friction. Refrigerated Programs — dual-sided sponge cushions keep vials fixed against bumps inside the fridge. Outdoor Transit — the impact- and pressure-resistant PETG shell shields fragile glass from drops, bumps and stacked-parcel extrusion.

The inner structure features four independent molded recessed slots that perfectly separate and hold individual 10ml vials without mutual collision or friction. Thick shock-absorbing sponge cushions are pre-installed on both the top lid and bottom base — the dual-sided lining tightly wraps each glass bottle, fixing it firmly in position to eliminate sliding and prevent breakage of high-value peptide samples. Food-grade PETG adds chemical resistance for long-term lab and refrigeration use.

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
