SPI Supplies^® Brand PTFE Round Bottom Flasks

The SPI Supplies^® brand of PTFE round bottom flasks represents a high quality type of labware that is totally inert, as all items are manufactured from pure virgin PTFE and can be used to a temperature of approximately 280°C (536°F). The finish is very smooth to minimize the chances of anything "sticking". Tapers match standard ground glass joints without the need for sealing rings.

Available shapes:
The round bottom flasks are available in two different patterns, the "full length" that is preferred in North America and the "medium length" that is more preferred in Europe and the rest of the world.
