    Digital Density Meter Model DDM 2910
    "I purchased this instrument three years ago as a replacement for a failing instrument. I have used similar instruments from Anton Paar and MT but this instrument is, by far, the least problematic. I have had zero issues in three years even though it is primarily used for measuring sulfuric acid concentration. Support and pricing are great and they are made in the USA. What else can I say?"

    7683 ALS
    "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."

    Application area: Paired with a 6890 GC in production and QC laboratories.
