Features and Benefits

Workstations with Static-Dissipative Tops
Workstations with Static-Dissipative Tops
  • Static-dissipative laminate (10^7 ohms/sq) safely dissipates charges to reduce ESD danger
  • Sealed undertop and clean materials— compatible with Class 100 / ISO 5 cleanroom
  • Adjustable “A” base is standard. Custom recessed “C” base shown
  • Custom modular overhead fluorescent light fixture provides shadow-free viewing
  • Nylon leveling feet resist a broad range of chemicals and eliminate wobbles for high-precision work
  • Other options include modular drawer unit, casework, shelves, power strip

This work station is ideal for static-sensitive materials that can be degraded or destroyed by the charges generated by conventional benchtops.

It features a dissipative laminate top bonded to a 1.25" (32 mm) high-density, epoxy-bonded fiber core. Edges are covered with plastic, and backing is provided on the bottom of the work surface to meet ISO 5 cleanroom standards.

Static-Dissipative Plastic Laminate combines the chemical- and heat-resistive properties of plastic laminate with a controlled path to ground for dissipation of static charge without voltage suppression ambiguity. This laminate has a micro-thin layer of aluminum oxide (moho hardness of 9; diamond - 10) integrated directly into its surface, creating an extremely hard protective layer, which provides long-term resistance to surface abrasion. This material has also been specifically tested for particle trapping (see test results below.) Each sheet used in fabrication is individually certified to meet the values set forth below:

  • General Thickness: .040 Nominal
  • Chemical Resistance: Resistive to common solvents such as Acetone, Trichloroethylene, Solder Flux, Isopropyl Alcohol, and Naptha
  • Thermal Resistance: 350°F with no charge per NEMA LD 3.06 and NEMA LKD 3.08; molten solder will not mar surface
  • Abrasion Resistivity: Typical NEMA Value—1550 cycles; Wear Rate of .006 gm/100 cycles
  • Cleaning: Clean with water only, or with a mild, nonabrasive, ammoniated detergent and rinse; DO NOT use wax or other coatings

These counts are very low. Under the same test conditions, a material which does shed particles would give off thousands of particles in the 10- and 5-micron range. This material is thus certified as cleanroom safe.

Non-Conductive Laminate shares many characteristics with static-dissipative laminate, except surface resistivity. In surface resistivity tests, this laminate material measured between 4.1 x 1011 and 7.4 x 1012 Ω/sq. It is generally resistive to most solvents as well as hot solder; however, mineral acids (such as hydrochloric, sulphuric, or nitric acid) should not be allowed to contact to laminate. This material is suitable for cleanroom use and will not outgas.

Clean, Versatile—and Static Safe

The dissipative laminate tops safely dissipate electrostatic charges to allow operations on static-sensitive devices—these benches meet MIL-B-81705-B specifications. They also resist a wide range of chemicals. Standard color is non-glare white.

Like our standard work stations, this station also features a heavy-duty bench frame made of all-welded square tubing. The heavy-wall tubing used in the construction allows the factory-mounted benchtop to support much heavier loads than conventional benches without sagging. The "A" base, adjustable from 25" to 34" (635 mm to 864 mm) floor-to-top feature a white epoxy enamel or powder-coat finish. Finished "A" bases are available with a 304 stainless steel lower leg member to provide this additional scuff protection. Include leveling feet to provide stability.

Other system options include easy-clean Modular Cleanroom Drawers and casework for efficient document and supply organization, with convenient access.

Many other models available: including static-dissipative and acid-resistant work surfaces, vibration-isolation systems, ErgoHeight™ and UltraClean™ work stations!

UL-Tested Cleanroom Workbenches for Highest Quality and Safety

Ensuring the safety of your personnel and equipment is essential. UL is recognized around the world as the leader in product safety testing and certification. Terra’s stainless steel cleanroom workbenches are tested by UL to meet the strictest safety and stability standards.

Adjustable Telescoping Legs

Workstations include telescoping legs to enhance ergonomics, reduce shipping cost, integrate with existing tables or casework, and support multiple operators who require different work surface heights. Each telescoping workstation is tested to ensure a weight load of 1,200 pounds.

Clean and Durable Powder Coat Finish

Terra’s signature white powder coat finish provides a high quality, durable barrier to protect against corrosion, plus a clean and attractive aesthetic. The advanced heat-fused formulation exceeds ASTM and ISO paint standards to resist chipping, scratching, fading, and wearing.

Cleanroom Non-Dissipative Table

Cleanroom tables with sealed dissipative or non-dissipative laminate tops are durable and cleanroom-compliant; powder-coated steel base with telescoping legs.

Cleanroom Table Work Surface Design

Laminate covers 100% of the fiberboard core; preventing mechanical damage that might cause the laminate to peel off

High Caliber Hardware

Seemingly small details like latches, ports, glides and hinges are often overlooked or ignored by other manufacturers, and later become the point of costly recurring maintenance or equipment failure. Terra’s products are made of long lasting, cleanroom compatible, top tier hardware. Individual components are carefully designed and rigorously tested to guarantee the highest quality, durability, and craftsmanship.
