Blackland Manufacturing has released a new guide explaining how chemical resistance ratings for laboratory countertops are determined and how they should be applied when selecting materials.
-- The latest guide outlines how these ratings are measured under standardized testing conditions and what laboratory managers, safety officers, and procurement teams should consider in terms of safety and durability when evaluating work surfaces exposed to acids, solvents, and cleaning agents.

Laboratory work surfaces are exposed daily to corrosive substances, making material selection a critical factor in both safety and operational performance. As the guide notes, surface failure can lead to staining, structural weakening, sanitation risks, and premature replacement, all of which can disrupt workflows and compromise experimental reliability.
“Chemical resistance ratings measure how well a laboratory countertop withstands exposure to acids, bases, solvents, and cleaning agents under controlled test conditions,” the guide explains, noting that these ratings are based on standardized ASTM and SEFA testing protocols.
The publication details how testing is conducted, from applying specific chemicals to a surface to evaluating visible and structural damage after a controlled exposure period. Results are then graded based on factors such as discoloration, softening, cracking, or surface deformation, providing a consistent basis for comparing materials.
Importantly, the guide emphasizes that these ratings are not fixed indicators of performance in every environment. Chemical concentration, exposure duration, and temperature can all influence how a surface responds, meaning that real-world conditions must be considered alongside test results.
“Not all lab countertops are created equal. The best chemical-resistant choice depends on your lab’s specific needs,” the guide notes, highlighting the importance of aligning material selection with actual usage conditions and not merely relying on generalized specifications.
The guide also addresses common misconceptions, including the assumption that “resistant” materials are immune to damage. Even high-performing surfaces can degrade if chemicals are left unattended or if seams and installation points are not properly sealed, it notes.
Blackland Manufacturing specializes in designing and fabricating laboratory countertops with precision that ensures resistance performance is maintained across the entire workspace. Proper seam integrity, edge sealing, and integration with laboratory pegboards and fixtures are details that the guide reinforces and that the company executes at the fabrication level. This expertise translates guide knowledge into reliable, installed solutions that meet the demands of challenging chemical environments.
The company is available to discuss custom laboratory work surfaces and fixtures, including epoxy and phenolic resin countertop designs.
