Indeed, the use of L instead of (lower-case) l, to avoid confusion with "1" (one) is a specific exception called out in the instructions for the use of SI abbreviations. Here is a reference: http://mathforum.org/library/drmath/view/64237.html

When using handwriting I tend to use the "cursive" form of the lower-case L to avoid ambiguity.

Personally I prefer the units be separated from the numeric value by a space, but the argument for connecting them includes avoiding the problem of accidental separation over a line break, viz. 3
mL

where 3mL would not ever get split.

Hmmm ...

To handle this situation you mention, I capitalize the 'L' ... i.e., show it as "1L". I have also used "mL" to represent milli-liters rather than "ml".

I.e., the comment inre "Liters" shortened to 'L' here: https://www.mathsisfun.com/measure/metric-volume.html seems right to me (space or no space).

So a one-liter flask is a 1l flask? Sure looks like eleven to me. (I'm using Courier right now.)
