User Profile for extractiontub
Recent Trends and Recommendations on extraction tubes wholesale: Recent trends in vacutainers include tubes made up of polyethylene terephthalate and use of various types of blood collection needles. Vacutainer tubes of recent introduction are made of a special formulation of the plastic, polyethylene terephthalate that is extremely strong, dimensionally stable, and resistant to chemicals and breakage. The manufacturers specify that all non-gel blood collection tubes, including those that contain heparin, EDTA and non-gel serum tubes can be centrifuged at ?1300 RCF for 10 minutes. There are also tubes that should be spun at room temperature at a speed of 1000 to 1300 RCF for 10 minutes in a swinging bucket centrifuge and 15 minutes in a fixed-angle centrifuge. These recent tubes are coated with silicone and micronized silica particles to accelerate clotting. A silicone coating reduces adherence of red cells to tube walls. The silica coating can sometimes cause the inner tube wall to appear cloudy and/or filmy. This cloudy appearance does not make the tubes unacceptable for use. Most Tubes are packaged 100 tubes/box and 1,000 tubes/case (10 boxes). The expiration date on the tube label is stated as a month and year. The tubes expire at the end of the month that is stated on the label. Vacutainer blood collection tubes have a sterile interior. Tubes are sterilized by gamma radiation (Wayman, 1994). These tubes are under a specific negative pressure. During the re-sterilization cycle: this negative pressure may be disrupted and therefore the tubes may not draw the proper blood volume. Thus, these tubes are sterile on the interior only. The manufacturer does not recommend re-sterilizing the tubes with ethylene oxide or autoclaving, due to pressure changes that take place during the re-sterilization cycle. Some manufacturers do offer a sterile peel-apart pouch that contains a 10 mL glass red top serum tube and 7 mL glass lavender top EDTA tube. 3mL and 6mL plain tubes with no added additives used as discard tubes are also available and find utility when drawing blood directly from an indwelling line or catheter. The tubes should be stored at 4-25'C (39-77'F) and requires inversions after a draw. An inversion is one complete turn of the wrist, 180 degrees, and back.
