Straight adapter with inner fritted glass between an outer/female and an inner/male Standard Taper 24/40 joint. Frit appears to be very coarse but is not labeled as such.
Despite being called a splash adapter, its main use is to prevent solids from being pulled into the condenser when removing solvent from a solid-solvent mixture.
Specs (seller measurements, not exact): length, 130 mm; fritted disc diameter, 20 mm
