| Bubbler Cylinders Precision Fabricators produces standard and custom cylinders (DOT 39, DOT 4B and others) with widely varying dimensions and performance characteristics, tailored to each customer's needs. If appropriate and permitted by DOT regulation (DOT 4B, 180.209, 180.211), Precision Fabricators will also refurbish previously used cylinders that have been properly cleaned and prepared at a cost significantly less than that of a new cylinder. Standard material is 316L stainless [845L UK, 4401 / 4436 Germany, SIS 2343-02 Sweden] and Teflon® coated stainless steel, Hastelloy, or other materials may be selected as desired. Our cylinders are the preferred industry choice for reliable, safe and cost-effective precursor delivery. | Bubbler Cylinder Specifications | | Volume (standard) | 100 ml, 200 ml, 500 ml, 1000 ml, 2500 ml | | Volume (custom) | 100 ml - 50,000 ml (50 L) | | Dimensions | Customers may select diameter, height, mounting features | | Materials | TP 316L Stainless Steel (standard), KEL-F (PCTFE)
