The “Reverse pipetting” function is used to ensure enough liquid is loaded if it is viscous, or after a Multi-Dispense (MD) command. There might not be enough liquid at the last dispense when you use MD command to transfer the liquid. So, it is recommended that "Reverse pipetting" be used to ensure the aspiration of more liquid to increase the accuracy of the last dispense.
After the APM dispenses the set volume of liquid, "Blow-Out" will dispense a little air. This “Blow-Out” function is used to ensure there will be no liquid remaining inside the tip after dispensing. A small amount can be left in the tip especially if the liquid is viscous. In such a situation "Blow-Out" should be used to push the last of the liquid out of the tip.
After APM has aspirated the liquid, “Air Gap” will aspirate a little air which will form an air gap in the tip. This “Air Gap” function is used to ensure the liquid will not drip when the APM does a liquid transfer. For example, an alcoholic liquid could easily drip and evaporate. A little air in the tip below the liquid can help to prevent this.
When using the Multi-Dispense (MD) command, the first and last dispense volume is always less accurate, due to the mechanical characteristics of the motor. For applications that require high accuracy, we recommend the selection of “Loading First Dispense to Source”, “Discard Last Dispense Back to Used Tip Tray” and “Loading Last Dispense Back to Source” in Advanced Setting.

Yes, EzStarter can import protocols as .csv/.txt format files. Users can set up LT (liquid transfer) and MD (multi-dispense) commands in this import protocol. Please contact us for detailed information.
- APM calibration needs to be done once a year.
- the X, Y, Z Rails and the APM driving rod need to be lubricated once a year.
- the UV lamp needs to be replaced every two years.
- the HEPA filter needs to be replaced every year or after 1,000 hours of use.
We recommend that the path length be set to the 0.5mm position for an unknown sample. The absorbance range of the 0.5mm path length is from 0.04 to 30A which covers almost all sample quantitative needs. If the measurement data >30A at 0.5mm pathlength, switch the selector to 0.05mm and measure again.
The lifetime of the Xenon lamp is approximately 10^9 flashes, it can last for 10 years or more. Xenon Lamp are very stable and the flash intensity changes very little over the lifetime of the lamp.
EzDrop 1000C will only accept an FAT or FAT32 formatted USB. Check the USB format before use.
