Bent Tweezers for Handling Wafers in Beakers

I am looking for a good way to submerge and retrieve my wafers in beakers for development. As I want to minimize my exposure risk to TMAH, I am looking for a way to hold the wafer perpendicular to the tweezers’ arms (hence I don’t need to scoop in my tweezers to try to lift the edge of the wafer and grab it. To illustrate, imagine these tweezers but bent 80-90 degrees instead. https://www.qsource.com/itemdetail/?itemCode=691B-SA-PI-E003&gclid=Cj0KCQiA15yNBhDTARIsAGnwe0XFnyeKXMm4KI8mkUOH4xe_QD2O7gKU5MljlWmDF17Vdq7C_8uAsFUaAlP0EALw_wcB

Any recommendations?
