High RCF (36,530 xg〜20,850 xg) Fixed angle rotor (for conical tubes)

Even at high centrifugal force, conical tube is less likely to get broken and high-viscosity proteins can be
clearly separated. (patented)
It is not necessary to reduce rpm to prevent damaging the tubes nor to select a specific conical tube.
Commercially available conical tubes can be used.

・ 50mL conical tubes (polypropylene [PP]), whose diameter of cap is up to 36 mm,
manufactured by Iwaki, Greiner,Corning, Sarstedt, Falcon, Fisher, Labcon,
Sumilon, Violamo and Nunc can be used.
・ A-508C rotor supports the use of 15mL conical tubes (PP) manufactured by Greiner,

Corning, Labcon and Nunc.
Tubes from other manufacturers can be used at 10,000 rpm or less.
A-6512C rotor supports the use of 15mL conical tubes (PP) from any
Autoclavable ＊ manufactures.

＊Code No. 055-1250 adaptor is required.

By utilizing the click mechanism for A-type fixed angle rotors, it is easy to handle on the level
of tightening of the rotor cover.
