The results of the ink bottle capacities are summarized in the table maintained on this page. What we measure is not the total capacity of the bottle (which will be marked for reference) but the capacity to allow the pen to be filled leaving the lowest residue when the contents are exhausted. The measurement methods are described in [https://www.penciclopedia.it/6933/fino-allultima-goccia/ this article (in italian)] on the blog and discussed in [https://forum.fountainpen.it/viewtopic.php?f=12&t=20844 this topic (in italian)] on the forum, where the results of the various measurements are also explained. Only the summary of the results is given here.

The results of the ink bottle capacities are summarized in the table maintained on this page. What we measure is not the total capacity of the bottle (which will be marked for reference) but the capacity to allow the pen to be filled leaving the lowest residue when the contents are exhausted. The purpose is to check how reliable the claim to fill "to the last drop" is.

 

 

 

The measurement methods are described in [https://www.penciclopedia.it/6933/fino-allultima-goccia/ this article (in italian)] on the blog and discussed in [https://forum.fountainpen.it/viewtopic.php?f=12&t=20844 this topic (in italian)] on the forum, where the results of the various measurements are also explained. This page is mainly used to report the summary of the results, we will limit ourselves to a brief summary.

 

 

We regarded (apart from the last case) as the limit of passage between one filling mode and another the step in which, maintaining that mode, the pen cannot be filled in a significant way, assuming as "significant" the amount of 0.8 ml of ink, basically the content of a short cartridge.

The table lists the capacities for three different filling modes:

The table lists the capacities for the four different filling modes:

* ''normal filling'': it is loaded with the bottle is placed horizontally in the ordinary position where it is also resting, inserting the pen from the mouthpiece without any shrewdness. This is the normal way to load a pen, the simplest and most convenient.

In the following table are listed only the value of the residue. For all of them an experimental error of 0.02 ml is applied with respect to the measurement (due to the systematic error of the balance, which has an accuracy of the centigram), but given the relative arbitrariness of the above definitions, consider a real accuracy of an order of magnitude less (i.e. 0.2 ml)
