Apparatus to neutralize static electricity present on the surface of containers (100; 100') and/or nests (200; 300), in which said containers (100; 100') form an ordered group of containers (100; 100'), each container (100; 100') of said ordered group of containers (100; 100') having a body that develops along a main axis of longitudinal extension of the container and in which a nest (200;300) has a plurality of seatings (212; 312) disposed according to an ordered matrix, each seating (212; 312) being configured to house, resting on it, a respective container of said ordered group of containers (100; 100'), and developing along an axis of symmetry substantially vertical and parallel to, preferably coincident with, said main axis of the container (100; 100') housed in said seating (212; 312), the axes of symmetry of said plurality of seatings (212; 312) being reciprocally parallel; said apparatus comprising: - an extraction member configured to engage at least one part of said ordered group of containers (100; 100') housed in said nest (200; 300), said extraction member being configured to perform a relative lifting movement with respect to the nest (200; 300) so as to at least partly extract from the respective seatings (212; 312) of said nest (200; 300) said at least one part of said ordered group of containers (100; 100') previously engaged, and to maintain said at least one part of said ordered group of containers (100; 100') extracted from the respective seatings (212; 312) in a raised condition, so that the seatings (212; 312) of said nest (200; 300), previously occupied by the containers, are left at least partly free; - at least one ionizing device configured to be relatively mobile with respect to the containers extracted and/or with respect to the nest (200; 300), while said at least one part of said ordered group of containers (100; 100') extracted is in said raised condition and said nest (200; 300) has the seatings left at least partly free by the respective containers (100; 100') extracted, along a path that develops in the proximity of the containers (100; 100') extracted and/or in the proximity of said nest (200; 300), so as to ionize the surrounding space and neutralize static electricity present on the surface of the containers (100; 100') in the raised condition and/or of the nest (200; 300) having the seatings left at least partly free by the respective containers (100; 100') extracted, said apparatus being characterized in that said extraction member comprises a plurality of inter-spaced arms, parallel to each other and defining at least one gripping loop, said at least one gripping loop being configured to house the containers (100; 100'), wherein said extraction member is configured to perform, before said relative lifting movement, at least one relative engagement movement with respect to the nest (200; 300), in order to house said at least one part of said ordered group of containers (100; 100'), laterally aligning said at least one gripping loop with at least one respective row of said ordered matrix of seatings (212; 312) and moving said at least one gripping loop in a direction of engagement, said direction of engagement being transverse with respect to said axes of symmetry of said seatings (212; 312), so as to house and hold said at least one part of said ordered group of containers (100; 100') in the at least one gripping loop. - an extraction member configured to engage at least one part of said ordered group of containers (100; 100') housed in said nest (200; 300), said extraction member being configured to perform a relative lifting movement with respect to the nest (200; 300) so as to at least partly extract from the respective seatings (212; 312) of said nest (200; 300) said at least one part of said ordered group of containers (100; 100') previously engaged, and to maintain said at least one part of said ordered group of containers (100; 100') extracted from the respective seatings (212; 312) in a raised condition, so that the seatings (212; 312) of said nest (200; 300), previously occupied by the containers, are left at least partly free; - at least one ionizing device configured to be relatively mobile with respect to the containers extracted and/or with respect to the nest (200; 300), while said at least one part of said ordered group of containers (100; 100') extracted is in said raised condition and said nest (200; 300) has the seatings left at least partly free by the respective containers (100; 100') extracted, along a path that develops in the proximity of the containers (100; 100') extracted and/or in the proximity of said nest (200; 300), so as to ionize the surrounding space and neutralize static electricity present on the surface of the containers (100; 100') in the raised condition and/or of the nest (200; 300) having the seatings left at least partly free by the respective containers (100; 100') extracted,
