Self-adhesive polyester printer labels Brady M4-82-492, black on white, 9.54 mm, 240 pcs

Brady M4-82-492 are self-adhesive polyester printer labels with black print on a white background, supplied as a roll of 240 small round labels. Each label measures 9.54 mm in diameter and is designed for durable identification and marking where compact, circular labels are required. The polyester material and permanent acrylic adhesive provide reliable attachment to smooth curved surfaces commonly found in laboratory, industrial and office settings.

Advantages

The polyester construction offers high chemical and abrasion resistance and remains stable at a wide range of temperatures. The ultra-thin label material conforms to curved and confined surfaces such as tubes, vials and cryocanes while maintaining legible print quality. A permanent acrylic adhesive ensures secure bonding to glass, polypropylene and other smooth substrates, reducing the risk of label loss in demanding environments. The labels are also compliant with RoHS requirements for restricted substances.

Suitable for

• Labeling test tubes, vials and microcentrifuge tubes
• Identification of cryogenic samples stored at very low temperatures
• Marking small components or parts where round labels are needed
• General laboratory and clinical sample tracking

Key specifications

• Material: polyester (ultra-thin)
• Print color: black on white
• Shape and size: round, 9.54 mm diameter
• Quantity: 240 labels per roll
• Adhesive type: permanent acrylic adhesive suitable for smooth curved surfaces
• Resistance: chemical- and abrasion-resistant; suitable for extreme temperatures including cryogenic storage

How to use

Load the roll into a compatible Brady handheld label printer following the printer manufacturer’s instructions. Design and print the required text or code using the printer software, then apply each label by pressing it firmly onto a clean, dry surface. For curved or small-diameter items, smooth the label from one edge to the other to ensure full contact and remove air pockets. Allow a short curing time for the adhesive to reach maximum bond strength before exposing labeled items to aggressive chemicals or extreme conditions.

Usage recommendations

For best adhesion and durability, clean surfaces of oils, dust and moisture before application. When labeling cryogenic samples, apply labels at room temperature and verify adhesion after cooling. Use printing settings optimized for polyester media to ensure sharp, long-lasting print results.
