"The 7683 ALS is a well-built sampler that has performed well in our production and Quality Control laboratories. In one of our production laboratories, run close to 10000 samples per year on our GCs. The 7683 handled the injections well for the first 5 years before giving us many "turret errors". Most errors were easily corrected with gentle cleaning of the turret. Eventually, it was discovered that the "turret errors" are caused by a worn roller on the vial stripper. This part is not sold separately as it was with prior generations of samplers. My only recourse seems to be to send the sampler in for refurbishment. If every part were available for purchase I would have given it an overall rating of 5 stars."
