When it goes through Tygon tubing, it comes out right. Laboratories don't specify Tygon lab tubing just for what it does. Because it's what Tygon tubing doesn't do that makes their tests come out right. What Tygon t u b i n g doesn't d o is alter or affect the nature of most solutions or gases it carries. So you're assured that your analyses won't fall victim to your tubing. That's especially important for successful reproducibility. Of course, there is a lot that Tygon tubing does do. It does safely handle most lab chemicals. It resists aging, hardening and cracking. It bends to tight curves without pinching. It cleans quickly due to its smooth, polished inner wall. And it allows immediate visual inspection, because of its glass-like clarity. So whether you need Tygon tubing for what it does or what it doesn't, just make sure it's Tygon tubing you're using. Look for the Tygon brand along every foot. There's one more thing that Tygon tubing doesn't do. It doesn't take long to get, because it's available at every major lab supply house.
