Type 1 borosilicate glass, clear, with or without screw thread

• Saves time and minimise the waste costs when performing quantitative analysis or storing materials
• Avoid alkalinisation of contents which may occur as carbonates leach from the glass with normal weathering

These tubes are convenient and ready-to-use clean packs which are pre-processed with a silanised surface deactivation treatment which plays an important role in preserving the integrity of certain materials or extracts stored in glass containers.
