Standard Test Slide for QuadCount™ , pk of 1

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).

Key Specifications

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:

1. Verify count accuracy — confirm the QuadCount's image-recognition algorithm reads the reference cell concentration within manufacturer accuracy spec
2. Verify viability discrimination — confirm the live/dead discrimination accuracy against reference viability percentages
3. Detect drift — identify systematic measurement drift that may indicate optical-component aging or algorithm calibration drift
4. Generate calibration record — produce a calibration log entry for institutional QM documentation
5. 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:

1. Initial chassis commissioning — institutional QM-managed labs commission a new QuadCount with a paired test slide for routine periodic-QC workflow.
2. Periodic recertification — calibration slides have a finite shelf life; replacement slides needed at the recertification date.
3. 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.
