Using sample volumes below the minimums specified
could result in:
• Insufficient sample being aspirated for testing.
• The pipettor striking the bottom of the sample receptacle,
causing damage to the product or receptacle.
NOTES
• For best performance when using low volume insert tubes, it is rec-
ommended that they be placed in a 75 mm tall primary tube.
• The minimum volumes listed must be present above the gel separa-
tion layers of serum collection tubes after centrifuging.
• To ensure proper liquid level detection when testing liquids with
extremely low dielectric properties, such as de-ionized water, use a
primary tube filled to near capacity with the liquid.
• To ensure proper liquid level detection when testing samples con-
tained in ampules, use a lint-free cloth or swab to carefully remove
any liquid film present at the ampule opening.
