This probe is especially used for the analysis of food products in liquid or near liquid state such as creams, sauces, jellies, soups and vegetable and / or fruit purees.
It consists of a base plate with a device to fix a beaker with a volume of 100 ml and a base with a diameter of 50 mm, plus an upper probe with interchangeable flat compression heads with diameters 35, 40 and 45 mm.
The beaker is mounted on the base plate, the upper probe with the selected head is lowered towards the test sample to ensure alignment between test probe and test sample, checking that the center of the upper probe and the center of the base of the beaker match. After this check, push the upper probe back to a height of about 10 mm above the top of the beaker.
Fill the sample container up to 75% of the total volume of the complete filling of the beaker and condition as required according to the test standard.
The reverse extrusion or “Back Extrusion” is a cyclical test, bringing the upper probe to the extension limit established with the METROTEST software and returning to the initial position..
This KIT of Reverse Extrusion (back extrusion) tests is mainly used for the analysis of food products in a liquid state or close to a liquid state such as gelatins, sauces, butters, pastes or other viscous liquids.
