Nova Biomedical BioProfile FLEX 2 pH/Gas Calibrator Cartridge LV

The Nova Biomedical (Part Number 57957) pH/Gas Calibrator Cartridge is a specialized consumable engineered specifically for the BioProfile® FLEX 2 Automated Cell Culture Analyzer. This "LV" (Low Volume) configuration is designed to provide the necessary calibration fluids for the system's MicroSensor™ Card, ensuring precise and drift-free measurements of critical culture parameters, specifically pH, pCO₂, and pO₂. Unlike traditional blood gas analyzers that relied on bulky external gas tanks, regulators, and humidifiers, this cartridge offers a streamlined, all-in-one solution that significantly reduces the instrument's footprint and complexity.

Functionally, the cartridge serves as the heart of the analyzer's maintenance-free operation. It houses both the calibration reagents and the waste receptacle in a single, sealed unit that snaps easily into the instrument's reagent bay. Embedded within the cartridge is a smart memory chip (RFID) that automatically communicates vital information to the FLEX 2 software, including the lot number, expiration date, and real-time fluid levels. This integration prevents the inadvertent use of expired reagents and allows the system to alert the operator exactly when a replacement is needed, ensuring data integrity during critical bioprocessing runs.

The "LV" designation typically indicates a Low Volume fill, making this specific part number ideal for laboratories with lower sampling throughputs or those running intermittent batches. This ensures that the lab consumes the majority of the fluid before the cartridge reaches its onboard expiration stability limit (typically 30 to 45 days after installation). Once installed, the system draws from this pack automatically to perform scheduled 1-point and 2-point calibrations, maintaining the sensor slope and baseline without any manual intervention from the user.
