The potential of covalent organic frameworks (COFs) for molecular separations remains unrealized because of challenges transforming nanoscale COF materials into large-area functional COF membranes. Herein, we report the synthesis of large-area (64 cm2), ultrathin (24 nm), β-ketoenamine-linked 2D COFs using a facile interfacial polymerization technique. Angstrom-level control over single-digit

The Acrodisc syringe filter with GHP membrane is amenable to any solvent or aqueous solution used in the lab. The GHP membrane is compatible with acids and bases, as well as aggressive organic solvents and halogenated solvents. These unique characteristics of the GHP membrane allow the Acrodisc syringe filter to serve as a universal membrane

However, some organic solvents can absorb into the membrane material, especially when in contact for long periods. This absorption makes the material swell, reducing pore size and affecting the performance of the filter. Some solvents might also chemically attack the material, releasing extractables into the filtrate.
