|
| ||
| Temperature Range: | The temperature range over which the thermal cycler will operate. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
| Heating Rate: | The rate at which samples can be heated. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| Cooling Rate: | The rate at which samples can be cooled. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| Temperature Uniformity: | A measure of the "equalness" of temperature over the entire thermal cycler. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
| Temperature Control: | The degree to which the thermal cycler can control temperature fluctuations. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
Block Type

|
| ||
| Block Type: | |||
| Your choices are... | |||
| Hot | The thermal cycler uses blocks that heat up. | ||
| Cold | The thermal cycler uses blocks that cool. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Gradient Heating or Cooling? | A temperature gradient can be achieved across the heating or cooling block. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||

| Peltier | The Peltier effect is used in many applications for the reliable cooling of sensitive high-temperature components without the need for refrigerants or compressors. Otherwise known as thermoelectric coolers, peltiers are a special type of semiconductor that function as a solid state heat pump. By applying a low voltage DC power source to one side, heat will be moved in the direction of the current (+ to - ). The heat is thus pumped from one side of the module to the other, so that one face will be cold while the opposite face will be heated. | ||
| Resistive | Resistive heating energy is applied to the sample through the walls of the thermal cycler. A resistive heating element is simply a coiled wire, very similar to the filament of a light bulb or the element in an electric toaster, that gets hot when electricity is through it. The heating element presses directly against the sides of the thermal cycler and conductive grease makes sure that heat transfers efficiently. | ||
| Passive Air or Water | The device does not contain a heating element. Water or air is heated outside the thermal cycler and then added to the instrument to heat the sample. | ||
| Other | Other unlisted or proprietary type. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
Capacity

|
|
| ||
| Number of Wells: | The number of wells in the microplate. Typical configurations are 96, 384 and 1536. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| Well Volume: | The volume of each individual well in the microplate. It is equal to the total capacity of the microplate divided by the number of wells. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
