A centrifuge device and method for use are presented. The centrifuge device includes a housing, a chamber, a channel, and a cover. The housing includes a first port and a vent opening and is designed to rotate about an axis passing through a center of the housing. The chamber is defined within the housing and is coupled to the first port. A first portion of the chamber has a width that tapers between a first width at a first position and a second width at a second position within the chamber, the first width being greater than the second width. The channel is coupled to the second position of the chamber and arranged such that a path exists for gas to travel from the channel to the vent opening. The cover provides a wall that seals the chamber.

The invention is characterized in that the locking element 50 is formed by a tilt lever which has the actuating member 56 mounted on its upper end and the latching element 58 mounted on its lower end, with its pivot axis being aligned perpendicular to the rotor axis R.

A rotor 10 of a centrifuge 100, having a receiving chamber 18 for samples to be centrifuged, a concentrically mounted seat 20 which is associated with a support 106 of a drive shaft 104 of said centrifuge 100, a lid 40 which limits the receiving chamber 18 at the top, which is mounted concentrically relative to the rotor and which has, on its side remote from the receiving chamber 18, a handle 44 for carrying the rotor and the lid 40, and a locking mechanism 50, 34b of lid 40 and rotor, which locking mechanism 50, 34b comprises a locking element 50 which can be moved between a locking position and an unlocking position thereof. In accordance with the invention, part of the handle 44 is adapted to be movable and is operatively connected to a retaining element 48b, 48c, which retaining element 48b, 48c can be moved, by the handle 44, between a first position which prevents actuation of the locking element 50, and a second position which releases the locking element 50.

A fixed angle centrifuge rotor includes a rotor body having a circumferential sidewall and a plurality of circumferentially spaced tubular cavities. Each tubular cavity has an open end and a closed end, and is configured to receive a sample container therein.
