Empty SPE Tubes allow you to pack your own SPE cartridges.

Retention Mechanism: Reversed-phase Sample Matrix Compatibility: Aqueous solutions (biological fluids, water) Polymerically bonded, octadecyl (18 %C), endcapped Higher 18 %C loading for increased binding capacities and higher recoveries The least selective phase: retains most…

Retention Mechanism: Normal phase Sample Matrix Compatibility: Organic solvents, oils, and lipids Unbonded acid washed silica sorbent ideal for normal phase SPE and other modified flash techniques Often used to separate or remove structurally similar molecules through successive…
