STEMvision Prev. Maint. (no warranty)

Keep colony counts reproducible between runs with this Preventative Maintenance offering from STEMCELL Technologies for the STEMvision automated imager used to enumerate colony-forming units in MethoCult media and equivalent semi-solid culture assays. The on-site service visit covers optical module alignment with focus verification, imaging sensor cleaning, mechanical stage inspection, firmware review against the current release, and a functional test against supplied reference standards run inside a 35 mm dish or gridded well plate format.

Hematopoietic CFC work, clonogenic progenitor studies, and other applications that depend on consistent image classification benefit from a documented touchpoint between full calibrations, since hardware drift is the most common source of run-to-run disagreement in colony enumeration.

Maintenance scope:

• Optical calibration and focus verification
• Imaging sensor cleaning
• Mechanical stage inspection and lubrication
• Firmware version review, with updates as required
• Functional test against supplied reference standards
• Replacement of common wear parts on a swap basis
• Updated maintenance log and written pass-or-fail report

STEMvision captures high-resolution TIFF images at 2.5x magnification and distinguishes erythroid, myeloid, and mixed lineage colony classes using built-in classification. A clean optical path and an aligned mechanical stage are the simplest way to keep that workflow within specification; this preventative service delivers that scheduled visit without the cost of a full warranty contract, with parts and labor billed per occurrence under the no-warranty arrangement.
