COD Test Tube Heater with 25 Vial Capacity

COD Test Tube Heater with 25 Vial Capacity

The HI-839800 thermo-reactor is made of sturdy materials and has a vial capacity of up to 25 simultaneous digestions. The reactor has three stored and three programmable (custom) temperature programs.

HI-839800 is supplied with:

• HI-740217 Laboratory safety shield
• Power cable
• Quick reference guide with instructions for manual download and instrument quality certificate

The stored programs support analysis methods at:

• 170 °C (all COD methods)
• 150 °C (all COD methods, Iron Total, Phosphorus Acid Hydrolyzable, Phosphorus Total methods)
• 105 °C (Chromium and Nitrogen Total methods)

Laboratory safety shield included

• The included safety shield is highly recommended to use during vial digestion procedure to maintain a safe working environment

Reactor block temperature continuously evaluated and displayed

• Built-in Countdown Timer
• A timer of up to 180 minutes is included for applications that require timed digestions. The end of the digestion time is signalled by an acoustic signal (5 short beeps) and “DONE” message is displayed. The heating is turned off and the block begins to cool off.

Status Indicator Lights

• POWER (on)
• HOT (surface)
• HEATING (in progress)

Overheating Prevention

• A thermal fuse in the reactor prevents overheating by turning off the heating element.

Reference temperature probe well

• A small temperature well can accommodate a temperature probe, useful for verifying the heating block.

Warnings and Error Messages

• The instrument displays warning messages when erroneous conditions appear and when values are outside the expected range such as high or low temperature, hot surface, or heating system malfunction.
