What is the difference between downdraft and side-draft grossing station ventilation?

Downdraft systems pull formalin vapors down through the work surface; side-draft systems pull air horizontally toward a rear slot. Downdraft is more effective with large open specimen containers; side-draft works better when the grosser's body blocks the downdraft path.

What exhaust volume does a pathology grossing station require?

Grossing stations typically require 400–600 CFM of dedicated exhaust per station. This must be confirmed with your MEP engineer based on formalin usage patterns and room size.

Can AME Series grossing stations be customized for ME office forensic workflows?

Yes. AME Series stations can be configured with chain-of-custody documentation systems, evidence photography lighting, and ME-specific casework layouts in addition to standard surgical pathology configurations.

What lighting color temperature is recommended for specimen photography at a grossing station?

5,000–5,500K LED task lighting is recommended for specimen photography to accurately render tissue color differentiation. The AME Series overhead task light is adjustable within this range.

Configuring a Pathology Grossing Station — Where Accuracy Meets Infrastructure

The pathology grossing station is the most configuration-intensive piece of equipment in a hospital pathology lab or medical examiner facility. Unlike a standard anatomy table that ships in a finite number of sizes, a grossing station is a custom-specified system where the configuration decisions — sink placement, ventilation integration, surface arrangement, lighting position, dictation system mount, and accessory integration — directly affect the speed and accuracy of the grossing workflow that the entire surgical pathology reporting cycle depends on.

This guide walks anatomy lab directors, pathology department chiefs, and ME facility planners through the key configuration decisions for the AME Series pathology grossing station. American Mortuary Coolers & Equipment manufactures grossing stations in Johnson City, Tennessee and sells factory-direct to hospitals, forensic facilities, and university programs nationwide.

What a Pathology Grossing Station Must Do

Core Functions of the Grossing Workflow

A pathologist or PA-C at the grossing station must: receive and log surgical specimens; photograph specimens with consistent lighting; measure and weigh specimens; section tissue with scalpel and blade; select tissue sections for cassette submission; dictate gross descriptions while working; and maintain contamination barriers between the work surface and surrounding areas. The grossing station must support all of these functions simultaneously — or as rapidly in sequence as the grossing pace requires — without forcing the grosser to turn away from the specimen, reach awkwardly for tools, or break sterile/clean boundaries.

The Infrastructure Demands This Places on the Station

Supporting this workflow requires: a primary work surface with integrated scale platform and photography back-drop; a sink with foot pedal activation for hands-free water control; local exhaust ventilation to capture formalin vapor from open specimen containers; task lighting at specimen-appropriate color temperature (5,000–5,500K recommended for tissue color accuracy); electrical outlets for dictation devices, imaging equipment, and task lighting; and a drainage system sized for formalin-rich tissue fluids and large specimen washdown.

AME Series Grossing Station — Configuration Dimensions

Station Width — Single vs. Double-Bay

The AME Series grossing station is available in single-bay and double-bay configurations. A single-bay station (typically 48–60 inches wide) serves one grosser and is appropriate for lower-volume labs or ME offices with one pathologist on duty at a time. A double-bay station (84–120 inches wide) provides two simultaneous grossing positions and suits high-volume hospital pathology departments with multiple grossers working morning accession periods.

For most community hospital pathology labs processing 50–100 specimens per day, a single-bay station with a 60-inch work surface is sufficient. Academic medical center labs processing 200+ specimens per day typically specify double-bay stations or multiple single stations in a grossing suite layout.

Sink Configuration Options

The AME Series grossing station integrates a stainless steel sink in the base unit. Configuration options include:

Left-sink configuration: Sink at the left end of the work surface, with the primary work area to the right — preferred for right-hand-dominant grossers who reach to the left for water without turning from the specimen.
Right-sink configuration: Mirror image of left-sink; preferred by some labs for plumbing routing reasons.
Center-sink configuration: Sink centered in the work surface with work areas on both sides — appropriate for double-bay or horseshoe grossing suite layouts where two grossers share a central sink.

All sink configurations include foot-pedal operation per biosafety best practice — hands never touch faucet handles during active grossing. The center-sink station and 4-foot pedal sink station are standalone sink options for supplementary hand decontamination positions. Our anatomy lab sink and scrub station guide covers sink selection in more detail.

Backsplash and Rear Casework

The AME Series includes a 24-inch tall backsplash with optional rear-mounted storage: slide box holders, cassette rack, blade disposal container bracket, and dictation microphone mount. Configuring these at initial order is far more cost-effective than retrofitting after installation — plan your rear casework layout during the specification process. The custom stainless steel casework system extends the grossing station with adjacent storage cabinets and work surfaces as needed.

Ventilation Configuration — The Highest-Stakes Decision

Downdraft vs. Side-Draft Ventilation

Grossing station ventilation comes in two primary configurations: downdraft (through the work surface) and side-draft (from a slot at the rear of the work surface). Downdraft systems draw air and vapors downward through a perforated surface into an exhaust plenum, removing formalin vapors that rise from specimen containers at the work surface level. Side-draft systems draw air horizontally from the front of the grossing area toward a rear exhaust slot.

Both configurations can achieve adequate formalin capture when properly engineered. Downdraft systems are more effective when working with large open specimen containers because they capture vapors at the surface level. Side-draft systems are preferred when the grosser's body position blocks the downdraft airflow path. Discuss your specific workflow with our team to determine which configuration is appropriate for your lab. See our Grossing Station Ventilation & Safety guide for full detail.

Exhaust Connection and Fan Sizing

The AME Series grossing station connects to your building's exhaust system via a 6-inch or 8-inch duct connection at the rear or bottom of the station. Gross station exhaust requires a dedicated branch from the building's lab exhaust system — do not share a grossing station exhaust branch with anatomy table exhaust or general lab exhaust without a mechanical engineer confirming adequate exhaust fan capacity. Required exhaust volumes for grossing stations typically run 400–600 CFM per station; confirm with your MEP engineer based on your specific usage pattern.

Imaging and Dictation Integration

Photography Lighting and Backdrop

Specimen photography at the grossing station requires consistent, high-color-temperature lighting and a neutral backdrop. The AME Series includes an adjustable overhead LED task light at 5,000–5,500K color temperature, positionable to minimize shadow on the specimen surface. A rear-mounted white or gray photography backdrop can be specified as part of the rear casework configuration.

Digital Dictation System Integration

Most modern pathology labs use digital dictation systems that integrate with the laboratory information system (LIS). The grossing station should include a dedicated outlet and microphone mount at the rear casework positioned at mouth height for a standing user. Specify the microphone mount position at time of order — retrofitting is awkward. The dictation device cable should route through the rear casework to avoid dangling across the work surface.

Compliance and Regulatory Context

Pathology grossing stations in hospital labs must comply with OSHA 29 CFR 1910.1048 (formaldehyde), CAP Laboratory Accreditation Program requirements, and Joint Commission Environment of Care standards. ME office grossing stations have additional forensic chain-of-custody requirements that affect documentation systems adjacent to the station. Our Compliance Roadmap covers all relevant regulatory frameworks. See also our Pathology Grossing Stations — Gold Standard guide and Essential Pathology Lab Equipment Guide.
