Reaction Vessel Assembly, 3 ml, New Style, Includes wrench, 5 umole, 10 umole, 20 umole scales
The RV Body is made from Kel-F which is the material that ABI originally made this item from. This material is translucent so you can see what is in it if you have a light behind it.
It has been our experience that the Kel-f material that is available currently is not very durable. We have experienced premature cracks in these reaction vessels. Our warranty is 3 months and we do not offer any extended warranty on these because of the issues we have experienced. We have tried to source Kel-f material from other vendors but we learned that all Kel-f come from the same source. 
We also offer the body made from PPS which is a more durable material however it is NOT translucent
