a drip unit comprising:
an exterior wall shaped to at least partially define a drip chamber that receives a liquid from a liquid source, wherein the exterior wall comprises a generally tubular shape, wherein the generally tubular shape comprises a reduced diameter portion and an annular surface, wherein the annular surface forms a seat;
a secondary exterior wall comprising a generally conical shape, wherein the secondary exterior wall receives the reduced diameter portion to engage the exterior wall with the secondary exterior wall; and
an anti-run-dry membrane comprising a plurality of pores that are permeable to the liquid, wherein the anti-run-dry membrane is formed of a hydrophilic material configured to resist passage of air through the pores, wherein the anti-run-dry membrane is secured to and contacts the secondary exterior wall, wherein the anti-run-dry membrane is proximate the seat.
