ALCOR introduces iSED, a fully automated ESR analyzer that can provide results in 20 seconds using a 100-microliter sample. The analyzer uses no disposables and does not require the user to monitor it while in use. Additional features include on-board sample mixing, a built-in bar code reader, direct through-stopper sampling, automatic sample ejection, and LIS interface capability. The 20-position sample wheel accommodates single or multiple samples in any order they are received. Seditrol bi-level quality controls remain on-board and ready for testing 24/7 on command.
