The PTFE separating funnels are isostatic ally moulded from pure virgin PTFE resulting in a highly inert material, with very heavy wall construction, one that could stand up to nearly everything one might want to put into them. The super smooth internal finish means that virtually nothing really sticks to it. The bottom is precision machined for good transfer of material. The stopcock  houses a PTFE encapsulated “O” ring seal for total leak-free performance. In addition, there are  mini-hand grips also for ease of handling.
