KSK2 Scientific, LLC · Model K225SDFSSBB
25 Cu. Ft. High-Performance Laboratory, Solid Door, Stainless Steel, Blood Bank Freezer. Features an intelligent microprocessor controller with a digital display. Preset to the ideal temperature of -25°C with a standard temperature range of -10°C to -30°C. Environmentally friendly, natural refrigerants are fully compliant with new EPA/SNAP/UL regulations. The K225SDF-SS-BB is Approved as a Class II Medical device and is manufactured under the highest quality standards: ISO 13485 – 2016.
Intended use: An electrically-powered device intended to be used to store and/or transport whole blood and/or blood components (e.g., blood cells, plasma) while keeping them cold (temperatures from 1° to 6° Celsius), or alternatively frozen (-18° to -30° Celsius). It includes refrigeration and freezing compartments with internal shelving, controls, sensors and alarms to signal out-of-range temperatures and power failures; its interior is typically corrosion-resistant (typically stainless steel or synthetic materials) to minimize the risk of adulteration, contamination, and/or corrosion of contents. The refrigeration unit is typically equipped with a safety thermostat to protect the products from freezing.
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Symptoms: Aspiration error, short sample, carryover.
Root cause: Clot/crystal obstruction.
Symptoms: Clogs, high blank, QC fail.
