The Problem

Light is killing your compounds.

Every time you open your fridge, light floods in. Research compounds are sensitive to light. Even brief, repeated exposure degrades them, and most people store their vials loose, directly in its path.

The Solution

Dark inside. Every time.

Stidra cases are 3D-printed in opaque PETG, a material that blocks light completely and holds its shape at refrigeration temperatures. Seal your vials inside, place the case in the fridge, and your vials stay in the dark, even when the door swings open.

Why Proper Storage Matters

You invest real money in every vial. Proper storage keeps them organized, shielded from light, and secure wherever they go.

Total Light Block
Every time you open your fridge, light hits your vials. Stidra's opaque PETG walls block 100% of light exposure, protecting compounds between every use.
Built to Last
Unlike brittle plastics, PETG resists cracking, handles refrigeration well, and maintains its shape over repeated use. It is the right material for a long-term vial storage case.
Keep Every Vial Organized
Precision-fit inserts hold each vial upright and reduce movement inside your refrigerator, cooler, or travel bag. Your case stays neat whether at home or on the go.
Made for You
Every case is printed after your order so you receive a freshly manufactured product in your chosen size and color. No sitting in a warehouse, no compromises.

02
We Print in PETG
Your case is printed to order in high-performance PETG — temperature-resistant, durable, and opaque to block 100% of light.
03
Load, Seal & Refrigerate
Snap your vials in, lock the clasp, and place it in the fridge. Your vials stay cold, dark, and protected every time the door opens.

Everything You
Need to Know.

PETG, a rigid, opaque thermoplastic that blocks 100% of light. No UV degradation, no transparency, no soft silicone that flexes and lets light creep in.

Three: Mini Case (2 vials), Standard Case (6 vials), Pro Case (10 vials). Each is sized precisely for its vial count. Nothing rattles.

Standard 2ml and 10ml lab vials. If you're running a standard protocol, it fits.

Anything you want kept dark, cold, and organized: research compounds, hormones, vitamins. If it matters enough to store properly, it fits.

Completely. Matte black, no external branding, no markings. It looks like nothing from the outside.

The case. That's it. No padding to lose, no accessories to track down. Just the case.

Choose your size above, add to cart, check out. Ships within 3-5 business days.
