Temperature Range: 4-99°C, Block Heating Rate: 3°C/sec, Block Cooling Rate: 2°C/sec, Block Uniformity: +/-0.4°C, Heated Lid Temperature Range: 115°C, Tube Control / Block Control / Simulated Tube Control / Simulated Block Control / Simulated Slide Control, 24.5x33x20.3 cm
| The ATC 401Thermal Cycler is a high performance, sub ambient, gradient thermal cycler.
 |  |  | 
|  | 
| It takes advantage of many of the new technological innovations embodied in the 701 and 801 models, while mintaning a very high economiical pricing structure.
 Features in the 401 include the unique helically controlled lid, the \"iQ-Therm\" dynamic temperature control modules and the largest full color, touch screen LCD currently available.
 The ATC 401 will accept the full range of interchangeable block and temperature control option and is gradient compatible.
 The ATC 401 offers a highly sophisticated thermal cycler at a very affordable price.  APOLLO CYCLER CHART
