Test fluid collection system

A test fluid collection system for a collection of metered quantity of a test fluid to be diluted for analysis, the system comprising:

• a housing comprising:
• i) a collection tip;
• ii) a collection port;
• iii) a dispensing inlet;
• and
• iv) a dispensing nozzle;
• wherein the collection tip is at a first end of the housing and is adapted to contact a sample of the test fluid;
• wherein the collection port is proximal to and in fluid communication with the collection tip and comprises two spaced members having opposing hydrophilic surfaces;
• wherein said surfaces define a volume between them which corresponds to the metered quantity of test fluid to be collected;
• wherein the distance between the spaced members enables the test fluid from the sample tip to be drawn into the volume by capillary action;
• wherein the collection tip and dispensing nozzle are at opposite ends of said housing;
• wherein the dispensing inlet is proximal to the collection tip, and in fluid communication via a dispensing channel to the dispensing nozzle which runs through said housing;
• wherein the housing is adapted to be fitted into the opening of a liquid container containing liquid for diluting the metered quantity of the test fluid, with said collection port and said dispensing inlet within said container, and with a seal fit between said opening and said housing;
• and
• wherein the dispensing channel decreases in diameter between 10-21% over the height of the dispensing nozzle and wherein the dispensing nozzle is flared at the dispensing nozzle exit to dispense drops of the diluted test fluid in a uniform manner from the container when the volume of said container is reduced and the diluted test fluid in said container is forced into said dispensing channel.
