Abstract
A laboratory centrifuge including at least one bucket receiving sample liquids and mounted in a swing-out manner on a rotationally driven rotor and further including a noise abatement system to reduce the bucket-generated noise. The system has at least one turbulence generator mounted on the external surface of the bucket.
Claims10
A laboratory swing-out type centrifuge comprising at least one swing-out bucket (5, 5′, 5″) receiving sample liquids and supported on a rotationally driven rotor (1) and further comprising a noise abating system (9, 9′) to reduce bucket-induced noise, wherein said system consists of at least one turbulence generator (9, 9′) mounted on the external surface of the bucket (5, 5′), wherein the turbulence generator is configured as an offset (9′) between two milled-out segments (12) that runs parallel to an axis of the bucket (5″).
The laboratory swing-out type centrifuge as claimed in 1, wherein the turbulence generator (9, 9′) is configured transversely to an air flow direction (8) in a region of a largest diameter of the bucket (5, 5′).
A laboratory swing-out type centrifuge comprising at least one bucket (5, 5′, 5″) adapted to receive at least one sample receptacle and supported on a rotationally driven rotor (1), said bucket further comprising a noise abating system (9, 9′) to reduce bucket-induced noise, wherein said system comprises a first and second turbulence generators (9, 9′), said first and second turbulence generators being at opposite sides of the bucket (5, 5′) and disposed on an external surface of the bucket, wherein at least one of the first and second turbulence generators comprises a recess formed in the bucket external surface.
A laboratory swing-out type centrifuge comprising at least one bucket (5, 5′, 5″) adapted to receive at least one sample receptacle and supported on a rotationally driven rotor (1), said bucket further comprising a noise abating system (9, 9′) to reduce bucket-induced noise, wherein said system comprises a first and second turbulence generators (9, 9′), said first and second turbulence generators being at opposite sides of the bucket (5, 5′) and disposed on an external surface of the bucket, wherein at least one of the first and second turbulence generators comprises an offset (9′) between two milled-out segments (12) that runs parallel to an axis of the bucket (5″).
