Custom Peptide Case: How to Design One That Fits Every Vial

Updated October 4, 2026 · 2 min read

Short answer

a custom peptide case is a hard case with a fitted pocket for each of your vials, sized to your exact count of 3 mL and 10 mL vials plus any extra bays you need. You design it in the PeptideCase™ builder, preview it in 3D, and it's 3D printed to order.

What makes a case a "peptide case"?

People use the term for a vial case built for small research-style vials, usually 3 mL and 10 mL glass vials. The case protects them from knocks and keeps them upright and organized. What matters is fit: vials that sit snugly don't chip, tip or rattle.

How to plan your layout

  1. Count vials by size. Most collections are mostly 3 mL vials with a few 10 mL.
  2. Group what you reach for together. The builder can keep one size in a single neat block.
  3. Leave room to grow. One or two spare pockets cost very little space.
  4. Add extra bays for pads, pens or tools, so nothing loose ends up in the case.

The planner arranges everything automatically and tries several layouts. It picks the one that's smallest and tidiest, with each vial size kept together where it can.

Pocket depth and grip

Every pocket is deep enough to hold the vial securely while leaving the top easy to grab. Short vials are raised so they sit level with taller ones and stay easy to lift out.

Labels and caps

If you want to tell vials apart at a glance, add custom-colored caps with an icon or letters. Read our custom vial caps guide.

Frequently asked questions

What vial sizes does a custom peptide case hold?

3 mL vials, 10 mL vials and slim 10 mL vials, in any mix, plus bays for other items.

Is a bigger case always better?

No. The best case holds what you carry plus a little spare room. A bigger case is heavier and harder to pack.

Can I add my logo?

Yes. Add text, an icon or your own logo to the lid in a second color.
