Aluminosilicate Glass
Aluminosilicate capillary tubes are harder than borosilicate making it more suitable for penetrating tough tissues.
Aluminosilicate (SCHOTT 8252)
Aluminosilicate softens at a higher temperature (935 degrees Celsius) than borosilicate and is workable over a much narrower range. It has a tendency to continuously thin out as it is drawn which allows extremely fine tips with very short tapers. For example, we have pulled aluminosilicate tips in the 20-30 nanometer range with taper lengths of 5-6 mm. Its resistivity is several orders of magnitude higher than borosilicate, thus reducing leakage currents when used in ion-selective micropipettes. Aluminosilicate is harder than borosilicate which results in a pipette that is more suitable for penetrating tough tissues.
