In the range of flow-meter™ products used in hospital suction applications, the MAK series large size containers for suctioned liquids has a long history, full of positive praises for their versatility, safety and economy. These devices have been designed and manufactured for “high flow and high vacuum” applications and are available with a capacity of 1000 ml with screw cap, of 2000 ml with screw and pressure lid and 4000 ml with pressure lid. Versions having capacities 1000 ml and 2000 ml can also be supplied, as an option, with a special lid with direct thread connection to the vacuum regulator. Jar and lid are made of polycarbonate, and two straight inlet/outlet connectors are integrated into the cover (except in the above mentioned version having direct connection to the vacuum regulator that fits one chrome-plated brass nipple with polycarbonate connecting nut). All containers are equipped with an overflow valve, are supplied with two spare elbow connectors, to set up any possible connection between the jar, the suction line and the patient, and are obviously autoclavable (121°C - 15 min ). If higher sterilization temperatures are required, a PSU version is also available for the three sizes (134°C - 18 min). An external graduated scale gives indications about the level of filling. In conjunction with the various supports and accessories available on request, the MAK collection jars grant simplicity in use, versatility and an important operating economy.
