Unlike other spiral platers, the Eddy Jet 2 does not use a permanent syringe to dispense every sample. The syringe can be discarded or it can be used again to dispense from the same sample – you set the parameters. There is no risk of wear and tear damage which can affect the deposition. There is no waiting for a cleaning cycle to first administer bleach then distilled water to rinse a permanent syringe. This critically protects against cross contamination or false negative results, caused by bleach residue.
