Easy access cover

A centrifuge comprising:

• a motor shaft;
• a rotor;
• a rotor body adapter housing that removably engages said rotor;
• a rotor hold down shaft;
• a coupling assembly;
• and
• a cover having a knob;
• wherein said coupling assembly secures said cover to said rotor and secures said rotor to said motor shaft.

A centrifuge comprising:

• a motor shaft;
• a rotor that engages said motor shaft;
• a coupling assembly;
• and
• a cover, said cover having a knob with a top surface, and an indicator disposed within said knob,
• wherein said knob has a knob pin contained therein, that engages said coupling assembly, said knob pin secures said cover to said rotor, and wherein said indicator is flush with said top surface of said knob when said rotor is secured to said motor shaft via said coupling assembly and wherein said indicator projects above said top surface of said knob when said rotor is released from said motor shaft.

An attachment and release apparatus for use with a centrifuge having a rotor and a motor shaft, comprising:

• a knob having a passage therethrough;
• a cover disposed around said knob;
• an indicator pin slidably disposed within said passage of said knob, said indicator pin having a first end and a second end and an axial slot within said knob;
• a knob pin disposed within said axial slot;
• an adapter removably connected the to the rotor;
• a housing with a second axial slot that includes a coupling assembly for coupling said cover to the rotor and for coupling the rotor to the motor shaft;
• a shaft having a first end and a second end slidably disposed within said adapter, wherein said shaft has a hole located at said first end;
• a shaft pin disposed within said hole of said shaft and disposed within said housing slot;
• a first biasing element disposed within said passage of said knob;
• and
• a second biasing element disposed within said housing.

A method for attaching and releasing a rotor to a motor shaft and attaching and releasing a rotor cover to the rotor, comprising:

• attaching the rotor to the motor shaft;
• attaching the rotor cover to the rotor, wherein the rotor cover includes a knob connected thereto;
• rotating the knob in a first direction,
• wherein said step of rotating attaches the rotor body to the motor shaft and attaches the rotor cover to the rotor body via coupling assembly which secures both the cover to the rotor and the rotor to the rotor shaft.

A centrifuge comprising:

• a motor shaft;
• a rotor;
• a rotor hold down shaft for engaging said motor shaft;
• a rotor body drive adapter housing wherein said rotor hold down shaft slidably engages said rotor body drive adapter housing;
• and
• a cover having a knob with a top surface, a knob pin and an indicator disposed within said knob, wherein said knob pin connects said cover to said rotor and wherein said indicator is in a first position relative to said top surface when said rotor is secured to the motor shaft and wherein said indicator is in a second position relative to said top surface when said rotor is released from said motor shaft.

A centrifuge comprising:

• a motor shaft;
• a rotor that engages said motor shaft;
• and
• a cover having a knob with a top surface and an indicator disposed within said knob, wherein said indicator is in a first position relative to said top surface when said rotor is secured to said motor shaft, and wherein said indicator is in a second position relative to said top surface when said rotor is released from said motor shaft.
