Which methods can be accelerated by using the HT200S?

With high speed digestion technology (HSD), the HT200S is a great solution for the busy lab, speeding up digestion times for a range of tests, saving time and money. It can produce COD results in just 35 mins, which is a massive time saving of around 2 hours and it can heat from 20°C to 148°C in just 8 minutes (20% faster than the LT200).  Cooling of the vials occurs in 13 minutes or under by m...
