Chemically Resistant/Cleanable Materials

Chemically Resistant and Cleanable Materials are engineered to withstand aggressive chemicals, frequent cleaning cycles, and strict hygiene requirements while maintaining mechanical strength, dimensional stability, and long-term reliability. These materials are essential for robotic and automation systems operating in medical, laboratory, semiconductor, food, and chemical processing environments.

At Norck Robotics, chemically resistant and cleanable materials are carefully selected and engineered materials that can resist corrosion, degradation, and contamination when exposed to chemicals, solvents, disinfectants, and cleaning agents. They are also designed to support easy and thorough cleaning, reducing the risk of residue buildup or cross-contamination.

Typical materials include:

• High-performance plastics such as PEEK, PTFE, PPS, and UHMW
  
• Stainless steels such as 316L
  
• Aluminum with chemical-resistant coatings or anodizing
  
• Advanced composites and engineered polymers

Chemical resistant materials are very important factor for lab automation systems - the fact is that almost all automation equipment is exposed to harsh chemicals, reagents, and solvents in one way or another during testing and analysis. Any material not chemically resistant is either going to break down, corrode, or leach to create contamination in the samples, thus damaging the equipment as well as the results. Strength and performance are maintained in chemically resistant materials, similar to stainless steel, PEEK, PTFE, or POM, even if repeatedly exposed to aggressive materials. The continuous chemical exposure ensures that the part will not degrade; the surface finish and smoothness allow for cleaning while preventing the buildup of residual matter and preventing cross contamination - and this is key to sterilizing and having consistent conditions in sensitive laboratory environments.

Prevents wear-and-tear on materials - Chemically resistant materials will not corrode or break down the material, and therefore preserves the long-term reliability under the aggressive lab environment.

Preserves sample chemistry - Non-reactive surfaces protect against adsorption or other chemical interactions with reagents.

Maintains cleanroom compliance - Smooth surfaces facilitate cleaning and reduce residue buildup and microbial growth for hygiene standards.

In terms of general lab automation systems , material options with high chemical resistances are crucial to give maximum durability and promote the protection of degradation and contamination of the automation components. Selecting material options with high chemical resistance will give the maximum compatibility with many of the most commonly used lab reagents and cleaning agents typically encountered in lab workflows.

• Stainless steel resistant to many acids, bases and solvents; Strong choice for many structural and mechanical components in automation systems.
• PEEK (polyetheretherketone) a high-performance plastic with good chemical resistance and thermal stability; Commonly made into liquid handling components.
• PTFE (polytetrafluoroethylene) have a very strong resistance to most chemicals and exhibit very low friction; Commonly used to make seals, tubing, and gaskets
• POM (polyoxymethylene, or acetal) has good resistance to many organic solvents and bases. Offers good mechanical strength and dimensional stability.
• Glass or borosilicate glass is mostly used in analytical devices and equipment because of its good thermal and chemical resistance.

Easy cleanability is important for laboratory-use components to ensure high hygiene standards, avoiding cross-contamination, and delivering repeatable and consistent test results. All automated processes use and track sensitive biological and/or chemical specimens and the seconds traces of residue can alter: the results, assay processes, or the experiments' span of time from test to assay settings.

• Smooth, non-porous surfaces prohibit the build-up of residues, and compatibility with disinfectants speed the cleaning and sanitizing process.
• Easy cleanability diminishes downtime between runs, and helps ensure compliance with a lab's safety and cleanliness protocols.
• In instances where biohazards, reagents, or pharmaceuticals are in use, regular cleaning is required, too - materials and finishes must endure intense cleaning cycles repeatedly without degradation.
• Cleanability helps ensure sterile conditions and maintain clean surfaces in laboratory environments, mainly clinical, diagnostic, and pharmaceutical laboratories. It also:
• Affects microbial growth, corrosion, or deterioration to some extent on a surface, as these can impact a systems ability to provide accurate measurements.
• Maintains the above requirements such as compliance with regulatory and governing bodies worldwide or the standards of the industry they work in (GLP, GMP, or ISO certification, etc.) that promote laboratory hygiene and safety.
