Patch Clamp Glass
A-M Systems is proud to offer Schott #8250 capillary glass. This is a direct replacement for Corning's discontinued #7052. As indicated in this table, the electrical and chemical properties of 8250 glass are nearly identical to Corning's #7052 . Most importantly, #8250 glass has a lower loss factor, which is correlated with lower noise recordings (see notes). Thus, we are confident that you will find your recordings with #8250 glass will be equal or better than recordings with #7052 glass. In summary, when compared to standard Borosilicate capillary glass #7740, #8250 capillary glass provides a lower loss factor, higher resistivity, and lower softening temperature (720 °C).
