NKHLB-400-3 Polymeric HLB SPE Cartridge, 400 mg/3 mL (CAT#: STEM-AL-0068-ZJF)

This product is a polymeric HLB SPE cartridge for extraction and cleanup of analytes. It contains a hydrophilic-lipophilic balance sorbent that combines hydrophobic divinylbenzene and hydrophilic N-vinylpyrrolidone functionality. The retention mechanism supports both polar and non-polar analytes. Its water-wettable sorbent helps reduce drying-related flow issues during SPE use. The cartridge is suitable for acidic, neutral, and basic compounds. It can be applied to biological, food, and environmental matrices. The macroporous polymeric structure supports broad pH stability and solvent compatibility. This model provides 400 mg of sorbent in a 3 mL cartridge format for increased sorbent loading.
