Lachat’s precision autodilutor, the PDS200, used with the QuikChem 8500^® Series Instruments, shines with numerous advantages:

• Uses a single, rather than dual piston system, decreasing the time per dilution.
• Improves accuracy—the PDS200 performs dilutions over the range of 1.6- to 4000-fold within 10% accuracy. Used with 13 x 100 mm tubes (21200) 90 position rack (21301L)
• Eliminates carryover issues.
• Easy to access tubing connections.
• Easy to clean and maintain.

Can be used to prepare standards from a stock solution, dilute samples known to be over range; and when the software detects an over range sample, it will be diluted automatically.
