To save money on consumables, many chemists choose to reuse
silica flash cartridges. This is true but risks purification results because chromatographic separation performance will change from run to run which reduces purification quality, especially in normal phase systems.
Regardless of the cartridge brand used, repeated use of silica flash cartridges results in loss of compound resolution and therefore fraction purity.

It’s important to replace these filters to ensure proper operation and protection of the internal solvent delivery valves. This filter not only traps particulates, but also protects the valves as particulates may get trapped within and could lead to improper solvent dispensing even when the extractors are at idle.

In medicinal chemistry reactions are often carried out in solvents such as DMSO. Once the reaction is complete, it is usually necessary to separate the products of the reaction from reagents and by-products. This can be performed using strong cation exchange sorbents (e.g. ISOLUTE SCX-2 or ISOLUTE Flash SCX-2) to selectively isolate the basic compounds from the reaction mixture. (see Figure 1 for structure of ISOLUTE SCX-2 and ISOLUTE Flash SCX-2 sorbents)

One of the most common work-up techniques in medicinal chemistry is liquid-liquid extraction (LLE) using a
separating funnel. The technique is used for removal of water soluble impurities, solvent exchange, water
removal or work-up of aqueous reaction mixtures.
