EK-RES X4 (R2.0) is a large high-quality standalone cylindrical reservoir. The first major distinction from the RES X3 is its sheer size with 250mm in height and the use of 80mm wide borosilicate glass tube. This provides a vast volume which allows the reservoir to hold up to 0.8 liters of liquid. This updated (R2.0) version of the EK-RES X4 features a nickel plated brass pillar that holds the top and bottom part of the reservoir together and it has a new redesigned anti-vortex insert. It can be disassembled much more easily as its predecessor with the enclosed Allen key.
