They had the scientific straight tube I needed, nobody local did I bought one that looked okay and it wasn't so I came here and they were awesome I got stuck with pink again but it works as a Medical user I have several layers of not caring what it looks like but they actually have 9mm wall thickness stuff which is handy because sometimes I am clumsy and I bump into stuff and at 9mm wall thickness it's much less likely to break and the connectors all fit properly! So I am pretty happy!
