Glass Tea Filter Tube with Cork / Mini Glass Tube Infuser

  •  To ensure the safe transportation of glass test tubes, we employ a robust packaging system comprising individual PE bubble bag, shrink wrap, foam boards, and cardboard boxes. This multi-layered approach provides excellent protection against potential damage during transit. Our test tubes are uniform bottoms, fire-polished rims, consistent lengths, and convenient packaged in shrink-wrapped inner box. The shrink wrap prevents any external elements or moisture from affecting the test tubes. The foam boards act as shock absorbers, minimizing the risk of breakage by evenly distributing the weight and preventing collisions between the tubes. Finally, the sturdy cardboard boxes offer an additional layer of security during handling and transportation. Individual PE bubble bag and custom partition carton are optional for additional protective packaging measures.

  •  Tubix Test Tube guarantees that no sale is complete unless the customer is satisfied.
