Any Ink Colour You Want… As Long As It’s Black: Our Updated Cleanroom Pens BlogCleanroom28.11.2025

Over the past two years, Micronclean has completely overhauled its range of cleanroom pens. In controlled environments, even the smallest detail can make a big difference, which is why we’re excited to introduce our updated range. Every pen has been rigorously tested and proven for use in cleanrooms and other controlled environments, delivering reliable performance without compromising contamination control.

Why Update Your Cleanroom Pens?

Cleanrooms demand strict attention to contamination control. Ordinary pens can shed particles, use unsuitable ink, lack robustness when sterilised, or even smear. Our updated cleanroom pens address these challenges head-on, offering:

  • Task orientation: Each pen is designed for a specific application, including a marker pen with proven IPA resistance.
  • Smooth, reliable ink flow: Ensures clear, legible records every time.
  • Durable, cleanroom-ready design: Built to withstand the rigours of controlled environments.
  • One ink colour: All pens have black ink for uniformity and compliance.

Our updated cleanroom pens combine usability and durability, helping your teams work efficiently. Whether you’re recording critical batch data, logging maintenance or simply keeping notes, these pens are built to perform in environments where precision matters most.

With Micronclean’s updated cleanroom pens, writing in a controlled environment has never been more reliable. Explore the range today and see how small details can make a big impact on your cleanroom operations.

And as Henry Ford might have said “You can have any ink colour you want as long as it is black”
