CHROMAFIX cartridges are PP cartridges with PE filter elements. Three different sizes with different adsorbent weights - Small (0.4 mL), Medium (0.8 mL), Large (1.8 mL). Especially suited for convenient solid phase extraction of small sample volumes. Female Luer fitting at the inlet, male Luer tip as exit. Offers alternative way of handling using positive pressure by syringes or peristaltic pumps.
