FAQS

MICROSAFE

Can I squeeze the tube while it is filling?

The tube fills automatically by capillary action. Squeezing or aspirating the tube can cause errors in
the sample by introducing bubbles or sucking the sample past the air vent.

Can MICROSAFE® be used for other aqueous fluids?

The volume measurement should be the same no matter what fluid. All our research and claims are based on handling
blood samples ONLY. Some caustic fluids might react with the tube. We can provide samples for testing with other
aqueous fluids.

Can MICROSAFE® be used to store or ship blood?

MICROSAFE® was not designed to be a storage or transportation container.

Does blood need to reach the indicator line to fill to the proper volume?

No. The indicator line is on the tube to help the user easily locate the air vent. The placement of the air vent controls
the volume. Capillary action will cause the blood to flow to the air vent and stop automatically.

Does MICROSAFE® contain latex, DEHP or BPA?

MICROSAFE® is free of latex, DEHP or BPA. An MSDS is available upon request.

How accurate is MICROSAFE®?

MICROSAFE® has a stated accuracy of +10% (never less than the stated volume) on the Device Specification, however, the tube is often even more accurate.

Is MICROSAFE® coated with anti-coagulants?

We do not coat MICROSAFE with EDTA, or any other anti-coagulant, for the following reasons:

MICROSAFE is designed for STAT tests at the Point of Care; it is a pick-up and delivery system for micro-whole blood from a finger-stick
 
Taking into account the small volume of MICROSAFE and the minimal amount of coating that would go inside, the process would do nothing to prevent clotting
 
If the anti-coagulant has no effect on the chemistries of your test, there is no issue with using MICROSAFE  
 
The manufacturing process of MICROSAFE renders outside introduction of an anticoagulant all but impossible.

Plastic does tends to clot blood slower than glass tubes

You have up to 30 seconds to keep the blood in MICROSAFE before dispensing is inhibited
 
MICROSAFE is implemented worldwide in POC Tests by leading industry providers without the need for anti-coagulant.

Is MICROSAFE® sterilized?

We do not sterilize our tubes.  Those few companies who sterilize MICROSAFE after purchase use a process called EtO (Ethylene Oxide Sterilization Process).  This is the only approved process for sterilizing MICROSAFE due to the 320°F melting point of PEBAX—the main component used in the manufacture of MICROSAFE—and therefore the tube cannot withstand conventional high temperature steam sterilization.

What about shelf life and room temperature for MICROSAFE®?

MICROSAFE® should be stored at room temperature and is assigned a 4 year shelf life.

What certifications does MICROSAFE® have?

Yes. MICROSAFE® is CE marked and manufactured to FDA QSR., ISO 13485:2003. MICROSAFE® also is registered with
the Canadian MDR and meets other quality and safety standards.

What MICROSAFE® volumes are available?

MICROSAFE® is available in pre-set volumes ranging from 5 ul to 80 ul. Custom sizes are available within the 5ul and
80ul range.
