Cleanroom Pens & Pencils

Cleanroom pens and pencils are essential for maintaining strict hygiene standards in controlled environments. Designed for cleanrooms, these writing instruments ensure contamination-free documentation, which is critical in labs and manufacturing facilities.

These pens and pencils feature specialized, low-particulate materials that prevent contamination. Cleanroom pens often have alcohol-resistant ink, allowing for durable, smudge-free writing even when wiped with cleaning solutions. Lab markers and cleanroom markers come in various colors and tip sizes, providing versatility for labeling and detailed notes. Alcohol-resistant markers are particularly useful for labeling vials, slides, and equipment that undergo frequent cleaning.

Available options include fine-tip, medium-tip, and broad-tip markers, as well as retractable and capped pens. Each variant is designed to meet specific needs, ensuring precise and reliable writing on different surfaces. Some cleanroom markers come with additional accessories like pen holders or clips, making them easy to carry and access during use.

Cleanroom pens and pencils offer reliable performance, contamination control, and durability, making them indispensable in maintaining cleanroom standards.

Thomas Scientific also offers a variety of other office supplies, such as cryogenic markers and notebooks.
