Abstract

A biosafety cabinet includes an operation, an operation space, a front plate, an operation opening, a vibration damping mechanism and an exhaust. The vibration damping mechanism is a mechanism that floats an operation object, which is disposed in the operation space, from the operation stage. The vibration damping mechanism includes a table which supports the operation object, and a magnet which is disposed in the operation stage. The vibration damping mechanism is a mechanism that floats the operation object from the operation stage by using a magnetic force.

Claims (12)

1. A biosafety cabinet comprising:

an operation stage above which an operation is performed;

an operation space in which an operator performs an operation;

a front plate that is disposed in a front surface of the operation space;

an operation opening that is connected to the operation space;

exhaust means for taking air in from the operation opening and exhausting air in the operation space outside the biosafety cabinet through air purification means; and

a vibration damping mechanism, wherein

the vibration damping mechanism is a mechanism that floats an operation object, which is disposed in the operation space, from the operation stage,

the vibration damping mechanism includes a table which supports the operation object, and a magnet which is disposed in the operation stage, and

the vibration damping mechanism is a mechanism that floats the operation object from the operation stage by using a magnetic force.

2. The biosafety cabinet according to claim 1 ,

wherein the operation stage is divided, and a connection member is disposed between one part of the operation stage on which an operation object is mounted and the other part of the operation stage to connect the parts of the operation stage to each other.
