on another shopping excursion, i found a 60cc (2 fl oz) syringe with
a large-bore "needle" that i think is designed to fit the duct in a
cow's nipple, rather than to puncture skin, etc. the barrel of the
syringe is just small enough to fit thru the mouth of a carboy, so
air-borne contamination is limited. my hydrometer tube needs about
3.25 fl oz, so i have to use the syringe twice to get a reading. i
think i paid $4 or $5 for needle and syringe, at a local store that
caters to farmers.
