Hi Anyone,

I would be pleased if you could explain & justify me the following sentence in detail.

If we use "ordinary" plastic tubes instead of glass tubes for blood grouping and crossmatching it will be very difficult to dislodge the cell button as plastic tubes have static electricity, because of this protein/albumin or antibodies get attracted to the plastic tube.

Thanks in advance

Regards

It might be a good idea for you to read the posts in a similar thread about plastic tubes. Go to the "Quick Search" area (near the top lefthand area of this screen) and type in "Plastic Tubes" and press the magnifying glass to do a search. Then read the thread titled "Hospital wanting to switch from glass tubes to plastic for serologic testing". There's some info in those posts that will probably be helpful to you.

Thanks L106 for the help, actually before posting my thread I did see the thread you have mentioned, but I didn't get any satisfied answers. So I had summarized what I felt was the message that the thread was trying to give me. And thought that someone would give a better & clear answer for the question or a detailed justification for my summary. Anyways, once again thanks for the help.

Fiza,

The answer you seek lies in the molecular surface of each type of vial. Plastic vials have a more open and charged molecular surface then glass. This property resides in the molecular construction of each type of tube. The open and charged surface of the plactic tubes is what generates the static electricity which causes variable attraction of what every liquids are dropped into the tube. The liquids we use are also charged so there are attracting and repelling charges which causes the variation in drop sizes and binding to the plastic. The molecular face of glass is much less charged and much more inert (ie does not react with other substances). I hope this sheds some light on your question.

Yeah, I'm happy with your answer & that's what I wanted.
