Buying Guide
Key considerations when choosing plastic test tubes with caps:
- Capacity: Match tube volume to your storage or display needs. Smaller volumes are ideal for beads and samples, larger volumes suit candies and party favors.
- Cap type and seal: Look for attached or screw caps with a reliable seal to prevent leakage, especially for liquids or powders.
- Material: PS and PET offer clarity and durability; choose non-toxic materials for kid-friendly uses.
- Diameter and length: Ensure fit with your existing racks or displays; standard sizes are typically around 16 mm diameter and 100–160 mm length.
- Rack compatibility: If a rack is included, verify hole spacing and overall dimensions to fit your setup.
- Intended use: For decor and crafts, clear visibility often matters more; for experiments, chemical compatibility and leak resistance may be prioritized.
