Varian Prostar 430 Autosampler

The 430 AutoSampler’s breakthrough loop injection technique with Pressure Assisted Sampling (PAS) combines precision with simplicity in a highly reliable design. PAS eliminates air bubble problems and sample contamination because it doesn’t use a needle port that can easily wears out. The 430 AutoSampler’s high-resolution syringe drive a partition syringe movement into 0.004-µl steps and achieves incredible injection precision at 1 µl or less.

Choose from three injection modes — 1. Full loop injection mode: when there is excess sample, the 430 overfills the installed injection loop for the best reproducibility (RSD < 0.3%). 2. Partial loop-fill injection mode: programmable injections from 1 µ l to 60% of loop volume offer precision (RSD < 0.5%) and minimize sample loss. 3. Microliter pickup injection mode: the exact injection volume is sampled. Then, a wash solvent positions the sample into the loop. There is no sample loss and reproducibility is better than 1.0% RSD. This Varian Prostar 430 Autosampler is in a great condition. It has been tested at SpectraLab Scientific. A 90 day warranty is included.
