235 Autoinjector

235 Autoinjectors are high-throughout, small-footprint injectors which accurately deliver microliter samples onto your HPLC, LC/MS or FIA/MS system with precise reproducibility. Peltier (P) heating/cooling and septum-piercing (SP) models are also available.

Cat. No. GA-241021

 

Features:

  • Large-capacity bed capable of handling up to 1,536 samples—perfect for overnight operation
  • Offer the flexibility to interface with a variety of detectors and pumping systems
  • Accommodate a variety of sample vessels from 384-well plates to 2-mL vials
  • Peltier cooling capability reduces evaporation, enabling smaller sample sizes and improved sample integrity
  • Software includes protocols for ISTD (internal standard addition)
  • Rinsing protocols for above and below injection port seals reduce carryover to <0.003%
