|  | Hot Bonnet® heated lid - with clamp-arm 
              action - keeps reaction vessels tightly sealed for reliable 
              oil-free cycling. These 'HB' models are available to fit either 
              0.5ml or 0.2ml tubes; retrofits are available. | 
              |  | Sophisticated Peltier-Joule heat pump - designed for 
              many years' service - delivers the expanded temperature range of 
              -9° to 105°C electronically, without the need for any bulky 
              mechanical refrigerator inside. | 
              |  | Extremely fast cycling, with ramping speeds that 
              average 1.8°/sec in the 50°-100°C range (max: 2.4°/sec). In 
              addition, any temperature may be held indefinitely, which allows 
              refrigeration of samples after a run. | 
              |  | Unparalleled thermal uniformity: ±0.4° within 12 sec, 
              ±0.3° within 40 sec of arrival at 90°C (well-to-well). | 
              |  | NIST-traceable thermal accuracy, with average of all 
              wells within ±0.3° of NIST-traceable standard at 90°C. | 
              |  | Compact, lightweight & portable - unit measures only 
              22x28x11cm high and weighs just 3 kilograms. | 
              |  | 'Instant Incubation' for digestions, ligations, etc. - 
              just a few keystrokes send the block to any temperature. | 
              |  | Large memory & amiable software with 32-character LCD 
              display. Memory stores up to 80 programs; rates of ramping or 
              incremental changes in the time/temp. of incubation can be 
              programmed with ease. | 
              |  | Interchangeable sample-block/heat-pump assembly with 
              choice of format (designed for occasional change): 16 x 0.5 ml tubes, for the ease of working with readily-available 
              microfuge tubes that you can write on;
 25 x 0.2 ml tubes, for use with the same thin-walled vessels that 
              are popular in the 96-well formats.
 | 
              |  | Optional in-sample probe allows control of reactions 
              through representative-sample temperature.
 | 
              |  | Power-failure protection so program execution will 
              resume after power interruptions of up to 12 hours. | 
              |  | Universal power circuitry allows operation anywhere in 
              the world without adjustment (100-240 VAC). | 
              |  | Two-year parts & labor warranty, optional extended 
              warranties; CSA-certified, & CE-marked. |
