Electropolished Stainless Steel Cleanroom Tables

Terra Universal manufactures the most advanced lines of electropolished 304/316 stainless steel work benches available for high-technology cleanrooms. For the cleanest tables, order BioSafe® rod-top or perforated-top work stations with easy-to-clean surfaces; fewer laminar flow air obstructions, and decreased accumulation of contaminating particles.

Vertical Laminar Flow Station  
Features Key
  Standard
  Option

A Electropolished stainless steel rods, 1/4" (6 mm) “float” on non-outgassing elastomer to minimize noise and vibration
B Select recessed “C” base (shown) or “A” base
C One-piece bullnose front edge enhances comfort and cleanliness
D Nylon leveling feet resist broad range of chemicals and eliminate wobbles for high-precision work


perforated table  
Features Key
  Standard
  Option

A Hidden reinforcements minimize dead spots, add strength and eliminate deflection (“oil can effect”)
B Select recessed “C” base (shown) or “A” base
C One-piece bullnose front edge enhances comfort and cleanliness
D Nylon leveling feet resist a broad range of chemicals and eliminate wobbles for high-precision work

Why is Electropolishing Critical?
Removes iron and other surface impurities that cause corrosion
Draws chromium and nickel to form a hard, protective finish
Removes irregularities (pits and burs) for an ultra-smooth surface that's easy to clean

Rods or Perforations?    
Both rod and perforated tops are designed to optimize the vertical laminar flow of particle-free air inside a cleanroom. From that point of view, both are superior to solid tops, which block air flow and create significant turbulence both above and below the work surface.
QuietTop™ Rod Top Benches   QuietTop™ Rod Top Benches
Rods create virtually no turbulence, but their open structure leaves little space to support small tools and parts. To solve this problem, Terra offers clip-on equipment mounts. Terra's standard QuietTop™ design uses 0.25" (6 mm)-diameter rods on 1" (25 mm) centers. Call for other rod sizes and configurations.   Perforations provide more surface area for supporting parts, but they do generate some turbulence in the gaps between the cut-outs. Terra's standard OpenTop™ perforations have a 0.25" (6 mm) diameter and open up 40% of the total benchtop for the air flow. Other hole patterns and sizes are available.
