Label for PCR tubes Brady B33-289-492-WT — white adhesive labels for microcentrifuge and PCR tubes

Brady PCR Tube Label B33-289-492-WT is a white adhesive label designed for marking PCR and microcentrifuge tubes. The label provides a printable surface compatible with direct thermal or compatible printers and is sized to adhere securely to small-diameter plastic tubes used in molecular biology workflows. Intended for laboratory sample identification, these labels support barcoding and clear alphanumeric marking to maintain traceability throughout PCR setup and analysis.

Advantages

These white adhesive labels offer a smooth, print-ready surface that accepts thermal print transfers for legible, high-contrast text and barcodes. The adhesive formulation is selected to bond reliably to the curved surfaces of microcentrifuge and PCR tubes without compromising tube handling or rack placement. Labels are thin and conformable to minimize interference with tube caps and automated handling systems while maintaining legibility after short-term exposure to common laboratory conditions.

Suitable for

• Labeling PCR reaction tubes and microcentrifuge tubes
• Sample tracking and barcoding in molecular biology workflows
• Temporary identification during sample preparation, amplification and storage at ambient or refrigerated conditions

Key specifications

• Color: white printable surface suitable for high-contrast text and barcodes
• Adhesive type: pressure-sensitive adhesive formulated for small-diameter plastic tubes
• Material properties: thin, conformable label material that adheres to curved tube surfaces
• Printer compatibility: direct thermal or compatible thermal transfer printing
• Application environment: suitable for typical laboratory ambient and refrigerated conditions; intended for short- to medium-term identification

How to use

Prepare the printer with appropriate media settings for direct thermal or compatible labels and design your identifier including alphanumeric text or barcode. Clean the tube surface if necessary to remove condensation or contamination, then apply the label centered on the tube body so that essential information is visible when the tube is placed in a rack. Press the label firmly onto the curved surface to ensure full contact and allow the adhesive to set before handling or placing tubes into automated systems.

Usage recommendations

For reliable printing and adhesion, store labels in a dry environment at recommended temperatures and avoid prolonged exposure to solvents or extreme temperatures. Validate barcode readability and label adhesion under your specific workflow conditions, and avoid applying labels over tube caps or sealing surfaces.
