Safety Stock. For critical applications where performance with MINIMUM downtime is required,
Barnstead/Thermolyne recommends that the USER maintain a local stock of those parts listed under
“General Maintenance” and "Safety Stock.” In the event of component failure, this stock can be drawn
upon by USER or Barnstead/Thermolyne technicians, thereby, avoiding unnecessary delays in delivery of
replacement parts.
