Tips for keeping your Molecular Devices™ QPix 420 Microbial Colony Picking System in good working order:
Daily Maintenance:
Ensure that the interior of the instrument is free from dirt and dust. Check the surface of the x-drive drag-chain support bracket. Dust and debris collected here can be swept onto the instrument bed during operation.
Before storing or cleaning the head, wipe the exterior of the head with a cloth using 70% ethanol. To store the head, slide it into its metal cover with the pins facing inward and then secure it in place with the thumbscrew and washer.
Check the air regulator for signs of moisture. If necessary, twist the drain clockwise approximately a half turn to force out moisture. Some types of regulators might require the drain purge to be pushed up towards the regulator bowl.
Weekly Maintenance:
If you use the external air compressor, drain the accumulated moisture from the internal air tank weekly.
If the instrument door shows signs of damage, a replacement door needs to be installed.
