What is an immersion dissection table?

An immersion dissection table holds cadavers in a fluid bath — typically a preservative solution — when not in active dissection use. This immersion method preserves tissue quality between lab sessions and eliminates the need for constant re-application of topical preservatives.

What is the difference between electric and manual immersion tables?

Electric immersion tables use a motorized mechanism to raise and lower the fluid tank or the cadaver platform, making the immersion and emersion process effortless. Manual tables require staff to physically operate a mechanical system to change the immersion level — more effort but lower cost.

What preservative fluid is used in immersion dissection tables?

Most anatomy programs use dilute phenol-based or formalin-based solutions, or proprietary commercial preservatives like Thiel fluid. The specific solution used affects tissue texture and preservation quality. Consult with your anatomy lab director on fluid selection.

How many cadavers can a single immersion table hold?

Most immersion dissection tables are designed for one cadaver per table. Anatomy labs typically have one table per dissection team of 4-6 students. Contact AMC for specific table dimensions and tank volume specifications.

Dissection Table Guide for Anatomy Labs — Electric vs. Manual Immersion Systems Compared

May 31, 2026 4 min read

Why Immersion Dissection Tables Are the Standard for Medical Education

Human anatomy education depends on well-preserved cadaveric specimens that maintain tissue quality throughout a full academic semester or year. Traditional surface preservation methods — repeated application of topical preservatives, plastic sheeting, and refrigeration — are labor-intensive and produce variable tissue quality. Immersion dissection tables solve this problem by maintaining cadavers in a continuous preservative fluid bath when not in active dissection use, providing consistent tissue preservation with minimal staff intervention between lab sessions.

AMC offers both electric immersion dissection tables and manual immersion dissection tables for anatomy education programs. For a broader view of anatomy lab equipment, see our anatomy lab dissection equipment guide and our anatomy lab equipment and immersion tanks guide.

How Immersion Dissection Tables Work

The Fluid Bath System

An immersion dissection table integrates a sealed fluid tank beneath or around the cadaver platform. When the cadaver is not in use, the platform is lowered into the tank (or fluid is raised to cover the cadaver) so that the entire specimen is submerged in preservative solution. The tank has a sealed lid to minimize evaporation and vapor release. Before each lab session, the cadaver is raised above the fluid level, excess fluid drains from the tissue, and dissection proceeds on the moist, preserved specimen.

Tissue Quality Benefits

Continuous immersion preservation maintains tissue hydration and pliability in a way that surface preservation methods cannot match. Anatomical structures remain recognizable and manipulable throughout extended dissection programs. Nerves, blood vessels, and fascial planes — the structures that students most need to identify and trace — retain their integrity through dozens of dissection sessions when properly immersed between uses.

Electric Immersion Tables: Features and Benefits

Motorized Platform Control

AMC's electric immersion dissection table uses a motorized mechanism to raise and lower the cadaver platform. The operator controls the platform height via a switch or control panel — no manual effort required for the immersion or emersion process. This motorized control is particularly valuable for anatomy programs where multiple lab sessions occur daily: the time and effort required to prepare multiple tables for each session is substantially reduced compared to manual systems.

Height Adjustment Integration

Many electric immersion tables also incorporate working height adjustment, allowing the raised platform to be positioned at the optimal dissection height for each instructor or student group. Combined fluid level control and working height adjustment in a single motorized system provides maximum ergonomic flexibility. See our electric immersion dissection table guide for detailed feature specifications.

Best Applications for Electric Tables

High-volume anatomy programs with multiple lab sections per day
Programs with larger cadaver inventories requiring frequent immersion/emersion cycling
Programs prioritizing staff ergonomics and reduced manual effort
Facilities with ADA-compliance requirements for motorized equipment operation

Manual Immersion Tables: Features and Benefits

Mechanical Simplicity

AMC's manual immersion dissection table provides the same fluid bath preservation benefit as the electric model through a manually operated mechanism. A hand crank, lever, or screw-jack system controls the platform height relative to the fluid level. Manual tables have no electrical components in the lift mechanism, reducing maintenance complexity and eliminating the failure mode of motor or control system malfunction.

Cost Considerations

Manual immersion tables offer a lower initial capital cost than electric models, making them the preferred choice for programs establishing an anatomy lab on a constrained budget, programs with lower cadaver volume (fewer immersion/emersion cycles per day), and programs where staff physical capacity is adequate for manual operation. The lower cost per table can be particularly significant for programs equipping a complete anatomy lab with many tables simultaneously.

Best Applications for Manual Tables

Programs with lower cadaver inventory and fewer daily immersion cycles
Budget-constrained initial lab setups
Programs in facilities where electrical service at each table position would require significant infrastructure investment

Making the Decision: Electric vs. Manual

Volume and Frequency Analysis

The primary decision factor is the number of immersion/emersion cycles required per day. If each table is immersed and emersed once daily (one lab session per day), manual operation is manageable with minimal staff effort. If tables are cycled two or three times daily (multiple sections), the cumulative effort of manual operation across all tables in the lab becomes significant — and the electric system's labor savings justify the additional cost.

Total Cost of Ownership

Factor both capital cost and operating cost over the expected lab life (typically 15-20+ years for stainless equipment). Electric tables have higher initial cost but lower labor cost over the facility life. Manual tables have lower initial cost but require ongoing staff time for each immersion cycle. Quantify both costs to determine which is the better investment for your specific program volume.
