4. Finger tighten the nut onto the union.
5. Ensure that the tip of the glass capillary protrudes about 7 mm from the
front of the knurled nut, as measured from the end of the nut to the
shoulder of the glass capillary, and then full tighten the nut onto the
union.
Warning:
To avoid injury with a sliver of glass
contaminated with toxic samples, do not touch the
sharp end of the capillary.
Caution:
The capillaries are extremely fragile. Handle them with
great care from their square-cut ends. Touching their sharp end
can render the needle inoperable.
