Im just wouldering cuz my house just got brand new carpit installed and my test kit leaks a little from the cap, almost like a drop or two. How come these kits do that? Any one know any replacment tubes that wont leak?
Well im still not to sure if they stain but i was able to get medical blood viels.. they had stuff inside them but i was told just to wash it out... they are sealed tight and i have about 500 of them so i can just throw them out
