draw sufficient
sample into tube L such that after wiping L clean and placing
the viscometer in the constant-temperature bath, bulb A will fill
as described above. The Cannon-Ubbelohde Semi-Micro design omits marks G and H since this viscometer is designed
both for semi-micro and dilution use; pour sufficient sample
through L into bulb A to ensure that capillary R and bulb C can
be filled as described in A2.2.6.
