845Z / 845Z PREP™ Injection Modules

The 845Z/845ZPREP Injection Modules give you the best of both worlds—high-throughput capacity with minimal carryover. Attaches directly to the Z-arm of the 215 Liquid Handler for aspirating sample directly into the loop.

Cat. No. GA-251551 (845Z) and GA-251552 (845ZPrep)

Features:

Shorter injection cycle times allows collection of early-eluting fractions to save significant time
No injection port means minimal carryover—less than 0.02% for analytical and prep methods
Low sample dispersion
