The SPI Supplies ETFE (ethylene tetrafluoroethylene) plastic tweezers
feature long length, with thin tips that are both curved and tapered. The
particular tweezer is excellent for pulling quenched tissue samples out of
liquid nitrogen, argon or even helium. The high chemical resistance
attributable to fluorpolymers generally mean that this tweezer will not be
affected by acids or bases and will never undergo any kind of "corrosion"
process.
