The E7500-STS1 is the Standard Test Slide accessory for the Accuris E7500 QuadCount Automatic Cell Counter, per the universe price-list label, a calibration / QC slide with reference cell-count standards used to verify the QuadCount's image-recognition accuracy on a periodic schedule. accessory.
Author confidence note (MEDIUM): Brochure context for E7500-STS1 specifically is sparse. The product description below interprets the universe label "Standard Test Slide" as a calibration test slide. Note: prior Accuris batch author_notes referenced E7500-STS1 as a "stain reagent", this conflicts with the slide-based interpretation. Confirm specific product identity at first order (calibration test slide vs stain reagent vs both; possibly a kit that bundles both).

What This Accessory Does (Inferred)
Standard test slides for image-based cell counters typically include reference cell-count standards at known cell concentrations and viability percentages. Running the test slide through the QuadCount workflow:
- Verify count accuracy. Confirm the QuadCount's image-recognition algorithm reads the reference cell concentration within manufacturer accuracy spec
- Verify viability discrimination. Confirm the live/dead discrimination accuracy against reference viability percentages
- Detect drift. Identify systematic measurement drift that may indicate optical-component aging or algorithm calibration drift
- Generate calibration record. Produce a calibration log entry for institutional QM documentation
- Trigger service intervention. If accuracy exceeds spec, trigger a service request before workflow data are affected
Compatibility & When to Order This SKU
Slide pairing: E7500 QuadCount only. Order this SKU when:
- Initial chassis commissioning. Institutional QM-managed labs commission a new QuadCount with a paired test slide for routine periodic-QC workflow.
- Periodic recertification. Calibration slides have a finite shelf life; replacement slides needed at the recertification date.
- Multi-chassis QM consistency. Institutional fleets standardize on one test slide per chassis for consistent QM documentation.
Application Profile
Institutional clinical-research and clinical labs. Operations under FDA 21 CFR Part 11, ISO 17025, GLP, or similar QM frameworks where periodic cell-counter calibration is part of audit-trail requirements.
Hospital reference labs running cell counts on patient samples. Clinical labs where QuadCount accuracy directly affects patient-result quality.
Pharma R&D and bioprocess QC labs. Drug-discovery primary-screen and bioprocess-QC workflows where cell-counter calibration is part of QM workflow.
Academic core facilities. Shared QuadCount instruments where periodic calibration documentation supports user-charge billing and QM reporting.
Ordering & Configuration
Confirm at order (per author confidence note): specific product identity (test slide for calibration vs stain reagent vs bundled kit), reference standards documentation (NIST traceability, reference cell concentration, reference viability percentage), recertification interval, and software-integration workflow.
Confirm at quote: chassis pairing (E7500 in inventory), specific product identity, recertification interval, institutional QM framework requirements, and lead time.
