A flow regulator for a liquid nitrogen droplet dispenser comprises a region (R) adjacent the outlet (14) and means for creating a back pressure (P) with said region thereby to reduce or inhibit the flow of liquid through the outlet. A suitable source of pressurising gas is the "boil off" gas from a bulk liquid nitrogen vessel.
