Customer Reviews
Real, verified reviews and photos from VialCase customers.
Keep the air inside your vial case dry. This vial-shaped holder fills with standard silica gel beads and drops into any spare vial slot of your case, so the desiccant lives right next to what you are protecting instead of loose in the lid. The hex-cage walls, floor and cap let air pass through while the beads stay put.
Capacity & sizes:
- 3 mL size: 16.5 mm × 39 mm — fits any 3 mL vial slot of 17.5 mm or larger
- 10 mL size: 25.4 mm × 54 mm — fits any 10 mL vial slot of 26 mm or larger
Key features:
- ✅ Hex-cage openings about 1.3 mm across — standard 2–5 mm silica gel beads cannot fall out
- 🔒 Screw-on cap with a printed buttress thread; the cap sits flush with the body so the holder fits between neighbouring vials
- ♻️ Refillable — ships empty; fill with any 2–5 mm silica gel beads (colour-indicating beads let you see when it is time to dry them out and reuse)
- ❄️ Fridge and freezer safe
- 🏠 Made to order in Las Vegas, NV
Care instructions: 🧼 Hand wash only with cold water · 🚫 Not dishwasher safe · Dry the beads, never the holder, in the oven.
Compatibility notice: ✔️ Designed for the current VialCase pocket sizes. Check that your case has a free 3 mL slot at least 17.5 mm across, or a 10 mL slot at least 26 mm across. In the 10-Slot 3 mL case the holder sits right beside the neighbouring vials.
General disclaimer: This product is a storage accessory only. Silica gel beads are not included. No medical, pharmaceutical or humidity-control performance claims are implied.
