3 Inch Glass Tube with Silicone Cap | Compact and Durable

The 3 Inch Glass Tube with Silicone Cap from GlassLab303 is designed for everyday portability and clean, simple storage. This compact borosilicate piece features a fitted silicone cap that keeps the interior protected and contained when not in use. Lightweight and easy to carry, it slips naturally into pockets, bags, organizers, or trays.

Each tube includes your choice of a blue or yellow silicone cap, adding a hint of color to a clear, minimal design.

Why It Stands Out

The silicone cap adds practical protection and keeps the interior sealed when stored. It helps maintain tidiness, prevents loose material from escaping, and offers a cushioned layer around the tip. Prepare it ahead of time if you like or keep it capped between uses for a clean, ready-to-go setup.

Color Options

Blue
Cool, understated, and modern.

Yellow
Bright, bold, and easy to locate among other items.

Care and Cleaning

Remove the silicone cap before cleaning. Rinse or soak the glass with a gentle glass-safe cleaner or isopropyl alcohol. Wash the silicone cap with warm, soapy water. Allow both components to dry completely before putting them back together. Store only when fully dry to maintain clarity and long-term durability.
