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.
