• All instruments are manufactured in the UK and supplied with a 3 year warranty.
• The anodised aluminium Heating Block inserts are supplied with a 1 year warranty.

Applications

• Applications include incubation, boiling, inactivation, wet washing, sample concentration, enzyme digestions, enzyme activity studies, nucleic acid hybridisations and many other clinical and industrial purposes.
• Larger three and four-block models are available for high throughput applications such as Chemical Oxygen Demand.

Countdown Timer

• Each digital unit features a countdown timer, which can be adjusted to time your experiment from anywhere between 1 minute and 100 hours, in 1 minute increments.
• To set the timer, press and hold the timer button and press the up or down buttons. Each press of the up or down buttons will increase or decrease the set time by 1 minute.
• If the buttons are held down, the time change will accelerate to 200 min per second. Release the timer button to activate the timer. An audible beep will indicate the timer is active. When the count-down has completed, an audible beep will be heard and the display will alternate between END and current temperature.
• Press the set/reset button to cancel the beeper.
• To cancel the timer, press and hold the set/reset button until STOP appears and an audible beep is heard.

Over-temperature cut-out

• In the event of a fault occurring allowing the Heating Block to overheat, a thermal fuse will cut in and remove power from the heater when the temperature reaches approximately 192°C in BH250-2, BH250-3 models and 240°C in BH250D models - eliminating any risk.

Accurate temperature control

• Highly accurate digital temperature control is made quick and easy with a bright 5-digit orange LED display.
• Each unit has a set point resolution of 0.1°C with temperature range from
  ambient + 5°C up to 100°C or 200°C depending on the model chosen.
• The Cole-Parmer® Heating Block facilitate a fast heat-up rate from 25°C to 100°C in 7-9 minutes, depending on the model chosen and all models are able to achieve a temperature stability at 37°C ± 0.1°C.
