NKHLB-250-3 Polymeric HLB SPE Cartridge, 250 mg/3 mL (CAT#: STEM-AL-0067-ZJF)

This product is a polymeric HLB SPE cartridge for solid phase extraction of analytes from complex matrices. It uses a hydrophilic-lipophilic balance sorbent composed of styrene-divinylbenzene copolymer with N-vinylpyrrolidone. The sorbent provides combined hydrophobic and hydrophilic retention for a broad analyte range. Its water-wettable behavior helps maintain uniform SPE processing after conditioning. The cartridge is suitable for acidic, neutral, and basic compounds. It is applicable to biological, food, and environmental sample cleanup. The polymeric network provides broad pH stability and compatibility with most solvents. This model provides 250 mg of sorbent in a 3 mL cartridge format.
