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 of the blood sample again and allow it to fill completely. Then align the tip with the sample and squeeze the bulb.

About this Product
MICROSAFE® is so much more than a plastic capillary tube. It is a one-piece, single-use device designed for collecting and dispensing micro samples of whole blood at the point of care.
MICROSAFE® is extremely easy to use and ensures that the correct volume of blood is delivered every single time. No more throwing away strips due to oversaturation or insufficient samples
We take all of the guess work out of the equation.
You handle the science. Let us handle the blood.
