NKHLB-150-3 Polymeric HLB SPE Cartridge, 150 mg/3 mL (CAT#: STEM-AL-0065-ZJF)

This product is a polymeric HLB SPE cartridge for sample preparation of polar and non-polar analytes. It is based on a styrene-divinylbenzene copolymer with N-vinylpyrrolidone functionality. The hydrophilic-lipophilic balance sorbent supports mixed retention behavior without relying only on hydrophobic interaction. Its water-wettable structure helps maintain cartridge function during SPE handling. The cartridge is suitable for acidic, neutral, and basic analytes. It can be used in biological, food, and environmental sample matrices. The sorbent supports broad pH stability and compatibility with most solvents. This model provides 150 mg of sorbent in a 3 mL cartridge format for moderate-capacity SPE workflows.
