Merck - Spectroquant® Thermoreactors

The Spectroquant® Thermoreactor TR 320 is designed for the digestion up to 12 samples simultaneously. Precisely controlled thermal digestion is a key sample preparation step during the determination of COD, TOC, total contents of cadmium, chromium, cyanide, iron, lead, nickel, nitrogen, phosphorus, silver, or zinc using our high quality Spectroquant® Test Kits.

• 8 stored standard programs
• Simultaneous digestion of 12 samples
• Features all you need for handling digestions simply and collectly

The Spectroquant® Thermoreactor TR 420 is designed for the digestion up to 24 samples simultaneously. Precisely controlled thermal digestion is a key sample preparation step during the determination of COD, TOC, total contents of cadmium, chromium, cyanide, iron, lead, nickel, nitrogen, phosphorus, silver, or zinc using our high quality Spectroquant® Test Kits.

• Free temperature and time selection
• 8 stored standard and 8 free programs
• Simultaneous digestion of 24 samples
• Thermosensor and PC cable available
• AQA documentation for control purposes
• Individual programming for future assignments

The instrument has already preinstalled all digestion programs necessary for wastewater analysis but can also be individually used in the temperature range up to 170°C and with digestion times of up to three hours.

The Spectroquant® Thermoreactor TR 620 is designed for the digestion up to 24 samples simultaneously. Precisely controlled thermal digestion is a key sample preparation step during the determination of COD, TOC, total contents of cadmium, chromium, cyanide, iron, lead, nickel, nitrogen, phosphorus, silver, or zinc using our high quality Spectroquant® Test Kits.

The Spectroquant® Thermoreactor TR 620 features two separate heating blocks, which can be individually controlled. Thereby, the Thermoreactor TR 620 enables users to set up and perform two different digestion programs at the same time – enhancing flexibility and reducing waiting times.

The Spectroquant® Thermoreactor TR 620 has the same functions like the TR 420 thermoreactor, but with two separate temperature-selectable heating zones.

• Two separate controllable heating blocks
• Possibility to run different digestion programs at the same time

It is e.g. capable of simultaneously digesting 12 COD and 12 TOC samples at different temperatures required, yielding results after just 120 minutes.
