Amber Boston Round Bottles
By Qorpak
Attached thermoset caps prevent dust and dirt from contaminating bottles before use and ensure that cap sizes match bottles. Choose caps that are pulp/vinyl lined, Polyseal, 14B white rubber, or PTFE lined. For the most demanding applications, the foam-backed PTFE liners resist virtually all chemicals at room temperature and provide resilience for a tight seal. Glass bottles also resist chemical attack, protect against permeation of gases, provide visibility for observation, and will not deteriorate with age.
