Discrete vs Flow
Many labs are familiar with the flow instruments that were extremely popular 20+ years ago. At the time, they offered an unprecedented throughput. Their major downside was that the user had to supervise the instrument while it performed the tests. Lab technicians spent countless hours counting spikes and changing tubing.
These flow systems were also more expensive than modern analyzers as each chemistry required a dedicated manifold.
Our EasyChem Plus and EasyChem 200 Discrete Analyzers address all of the issues flow instruments suffered from.
Our instruments can be left unattended to run up to 200 tests/hour. Besides increasing the speed over manual testing, many labs program the instrument at the end of the day to run a series of tests after the lab is closed for the day and retried the collected data the next morning.
Discrete analyzers are substantially easier to maintain too. With less tubing, and few moving parts, the instruments require little maintenance. There are protocols that we recommend to extend the instrument's life which we review during training.
The biggest difference between flow instrument and discrete analyzers is the cost of operation. Discrete analyzers use substantially less reagent and the cost of consumables is almost nothing.This helps labs keep costs down while performing the tests they need to run.
Tests can be performed in parallel on the same sample. If you have a set of samples that you need to test for Phosphate, Nitrite and Cyanide, you can test all 3 parameters on the same instrument in the same test run. No additional manifolds required.
