Do you have the casting tray for 7 cm X 7 cm gel? I bought size 7 cm X 10 cm that did not fit our tank.
The manufacturer does not have any gel casting trays that are 7cm x 7cm. They did advise that they have multiple sizes for item # JSB-30 Jordan Mini Gel-O Submarine Horizontal Electrophoresis System but they can only be used for the JSB-30system. The smallest for the JSB-30 system is 7.5cm x 7.5cm .
