GENERAL INFORMATION | STANDARD OPERATING PROCEDURE
The Laurell spin processor housing has been machined from Natural Polypropylene. Nitrogen purged process chamber is standard. 20 program / 51 steps are available, step time from 0.1 seconds to 99 minutes 59.9 seconds. Repeatability specification is <0.5 RPM with no accumulation of error

OPERATION
Since new spinners are available in the designated hoods. The laurell spinner is now used for non-standard materials coating such as PDMS etc. After a substrate is loaded on to the chuck, vacuum hold-down is engaged from the side mounted control panel and the lid closed, a preprogrammed process is selected and initiated. When in program mode (with safety interlocks satisfied), any step can be viewed, changed, or activated. When the spin is completed "END" is displayed and must be cleared by opening the door (presumably to change substrates) or changing programs. This can be bypassed for running the same process twice.
