- From DURAN® glass with its good thermal shock and chemical resistance. Filter funnels mate to the filtering flask via a conical rubber seal (GUKO).
|
- Typical applications: qualitative inorganic analysis and preparative chemistry.
|
- Due to their high chemical and thermal shock resistance DURAN® filters and the corresponding filter plates are ideal for separations, e. g. with strong acids or alkalis. Thus they offer advantages in comparison with other materials such as plastic or paper. DURAN® filter products have a maximum operating temperature of +450 °C and are therefore far superior to other materials.
|
- Uniform heating is recommended to avoid thermal stresses and resultant breakages.
|
- The heating or cooling rate should not exceed 8 °C/min.
|
- When filtering hot substances observe the thermal shock resistance and, if necessary, preheat the filtration apparatus in a drying cabinet.
|
- Wet filtration apparatus should be heated slowly up to +80 °C and dried for one hour before increasing the temperature further.
