The Hanna Hanna Instruments-839800 thermo-reactor is an easy to use test tube heater with the capacity to perform up to 25 simultaneous digestions.

Complete with a countdown timer, it can be used for timed or infinity testing procedures.

Robust and durable, the main body is machined from a single block of metal.

Temperature within the block is controlled using a sophisticated electronic thermostat and can be verified by placing a thermometer in the temperature well provided.

The reactor is equipped with 6 pre-defined and 2 user-defined °C profiles.

Dedicated temperature profiles for COD and total phosphorus reactions are pre-set to 150°C.

The total nitrogen analysis temperature is pre-set to 105°C

In adjustable temperature mode (50 to 150°C), the heater can be used for other samples that require different digestion temperatures.

Key features:

Heater block temperature is continuously evaluated and displayed on the LCD

Low temperature alert indicates that temperature is below set value

High temperature alert warns when temperature rises above the set value

Reactor has a thermal fuse that prevents overheating by disabling the heater

Countdown timer shows time remaining until heating element shuts off

A three hour countdown timer is ideal for timed digestion

The sound of a 'beep' indicates when the timer has expired and the heating element turns off

To operate in infinity mode, the timer can be used without the shut-off feature

Visual power indication Green LED indicates power on Blinking red LED warns if heater exceeds 50°C Yellow LED indicates heating is active
