Laboratory cabinet device for storing laboratory samples, comprising a chamber housing with a front side and a chamber opening of the front side through which the chamber interior is accessible, a chamber door for closing the chamber opening in a closed position of the chamber door, a closure device (10, 7a, 7b) for holding the chamber door at the front side in the closed position by a magnetic holding force, wherein the closure device comprises an actuating element, a first holding element and a second holding element, wherein the first holding element is fixed to the actuating element and the second holding element is fixed to the front side, and the actuating element is pivotally mounted to the chamber door so that the actuating element is pivotally movable between a first open pivoted position, in which the first and second holding elements cannot exert magnetic holding force on each other, and a second closed pivoted position, in which the first and second holding elements can exert the magnetic holding force on each other, wherein the actuating element extends parallel to the main plane of the chamber door and has an end which is formed as a grip tab portion which in the second pivoted position projects beyond the edge of the chamber door so that in the closed position of the chamber door and in the second pivoted position of the actuating element the magnetic holding force of the closure device (10, 7a, 7b) can be overcome by the user both by rotating the actuating element from the second pivot position to the first pivot position and by pulling the chamber door by means of the grip tab portion in a direction perpendicular to the main plane of the chamber door. a chamber housing with a front side and a chamber opening of the front side through which the chamber interior is accessible, a chamber door for closing the chamber opening in a closed position of the chamber door, a closure device (10, 7a, 7b) for holding the chamber door at the front side in the closed position by a magnetic holding force, wherein the closure device comprises an actuating element, a first holding element and a second holding element, wherein the first holding element is fixed to the actuating element and the second holding element is fixed to the front side, and the actuating element is pivotally mounted to the chamber door so that the actuating element is pivotally movable between a first open pivoted position, in which the first and second holding elements cannot exert magnetic holding force on each other, and a second closed pivoted position, in which the first and second holding elements can exert the magnetic holding force on each other, wherein the actuating element extends parallel to the main plane of the chamber door and has an end which is formed as a grip tab portion which in the second pivoted position projects beyond the edge of the chamber door so that in the closed position of the chamber door and in the second pivoted position of the actuating element the magnetic holding force of the closure device (10, 7a, 7b) can be overcome by the user both by rotating the actuating element from the second pivot position to the first pivot position and by pulling the chamber door by means of the grip tab portion in a direction perpendicular to the main plane of the chamber door.
