Using the MICROSAFE Tube

CAUTION! Filling is automatic: Never squeeze the tube while sampling.

Don't squeeze the bulb; MICROSAFE fills by capillary action.

Step 1: Hold the tube horizontally, and touch the tip of the MICROSAFE® Tube to the blood sample. Capillary action will automatically draw the sample to the air vent and it will stop.

Step 2: To expel the sample, align the tip of the tube with the sample target and squeeze the bulb.

If a sample won’t expel, you probably didn't allow for the tube to fill all the way. Touch the tip to the blood sample again and allow it to fill completely. Then align the tip with the sample target and squeeze the bulb.
