We are experiencing chemical level drops in our chemical bubbler.  Is this a temperature issue or should we be focusing on other variables?



Once the chemical bubblers are at proper levels and stable temperature the vapor deposition can start. It is important to ensure your bubbler temperature control can respond to flow changes and liquid levels quickly, to ensure a constant vapor stream for each deposition pass. If programmed flow rate changes from low to high, or chemical levels drops significantly, bubbler temperature may drop and reduce vapor pickup rate.

Update: Read our section on Chemical Bubblers in the blog, Preparing to Manufacture an Optical Fiber Preform that includes tips and prevention.
