Description

15ml Glass Filter Crucible with Sintered Disc, 5 grade porosity

Glass type: Borosilicate 3.3 according to DIN 12348 - Glassco brand

Standard specification for glass in laboratory apparatus: ASTM E 438, TYPE 1, CLASS A - low-expansion borosilicate glass

The thermal resistance is significantly lower than that of standard Glassco glass, so they cannot be subjected to excessive temperatures or direct contact with flame or fire.

As far as the weight consistency of the crucible is concerned, from room temperature onwards it can be placed in a drying oven at 150 °C, even though the temperature of 110 °C is generally used.

The crucible can be safely heated in the drying oven to 500 °C provided that the incorporation of the temperature and heating is gradual

Items with grade 4 and 5 porous plate if cold and wet should not be subjected to a sudden change in temperature as the water vapour pressure may be sufficient to break the filter.

The crucible should be turned upside down inside the furnace or sterilizer.
