Reagent bottles, also known as media bottles or graduated bottles, are containers made of PTFE (Teflon), and topped by PTFE caps and are intended to contain chemicals in liquid or powder form for laboratories and stored in cabinets or on shelves. Appropriate for most chemicals and solvents, the show requisite inertness, and are acid and alkali resistant. PTFE bottles are chemically inert, non-contaminating, and are thermally stable in the range of -200°C (390°F) to + 280°C (+536°F). The bottles also have a “super smooth” finish making it virtually impossible for anything to “stick” to the surface of these fine laboratory products.

The bottles are isostatically 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 base is precision machined for good heat transfer on a hot plate. The screw cap houses a PTFE encapsulated “O” ring seal for total leak-free performance. In addition, there are  mini-hand grips also for ease of handling.
