NJ graphite digester pore digestion device can be used with 55ml microwave tank

  1、 Product introduction graphite digester is a representative pore digestion device, which uses graphite block as heat conduction medium
It heats, cultivates and dries the samples in a circular heating mode, which effectively increases the utilization rate of heat energy
At the same time, it occupies the front end of conventional digestion equipment with the advantages of higher temperature control accuracy, small difference between holes, high digestion efficiency, energy saving and environmental protection

2、 Application case
Ø Weigh 25ml water sample, put it into 50ml Teflon tube and shake it well

Ø Put the sample tube into the graphite digester for digestion

Ø After digestion, put the constant volume sample on the machine for detection

(sample addition: 2ml nitric acid; heating: 140 ℃, heating time: 20min, holding time: 2h; cooling: 5min; constant volume: 25ml
)
