For coloured fluids the level of higher meniscus is taken as the indicator of volume though for colourless fluids amount of the reduced meniscus is taken.
These tubes are joined for the upper end by a plastic or rubber bulb and taper right down to a little orifice at The underside finish. Teat pipette is actually a expression for combining a glass Pasteur pipette along with a rubber bulb.
