The "UL" is a typewriter abbreviation for Mucro Liter or 1/1 000 000 of a Liter. Properly a Greek letter is used in place of the "U". 40 UL is 40/1 000 000 of a Liter at full capacity. 100 UL is 100/1 000 000 of a Liter at full capacity. Perhaps this is enough for the questioner.
"ul" might refer to microliter, same as cubic millimeter. When there are technical difficulties to show the "mu" symbol, it may be replaced by the letter "u", which looks somewhat similar.
