RAPIDGRAPH - REPLACEMENT INK CARTRIDGE SYSTEM

 

ISOGRAPH - REFILLABLE INK RESERVOIR SYSTEM

 

What's the difference?

 

The Rapidograph Pen uses Rotring’s innovative capillary cartridge including the ink helix.  Each time you change the cartridge you get a new clean ink helix and pressure equalisation system.  You never have to clean the ink helix!  This makes the Rapidograph Pen the more popular of the two as it is a lot less messy and is less likely to get clogged up. The extra-large volume of the ink helix and the location of the ventilation opening allows for improved temperature stability.  The ink can therefore be used right down to the last drop!

 

The Isograph Pen features a refillable ink reservoir.  The patented push-on sleeve allows for easy access to and fast cleaning of the ink helix, even when the reservoir is full.  The Isograph is ideal for frequent drawing using bottled inks. This means that your colour range is more versatile with an Isograph Pen as you refill it yourself.
