Heathrow Scientific Microscope Slide Tough-Tags Polyester Laser Labels 2400/Pack

Standard paper labels dissolve in xylene, curl off slides in immersion oil, and smear when wet — the routine hazards of a histology or pathology workflow. Heathrow Scientific Microscope Slide Tough-Tags are made from polyester: chemically resistant to xylene and organic solvents, waterproof, and autoclavable. The 7/8 × 7/8 in (0.88 × 0.88 in) format is sized specifically for the frosted label area of standard microscope slides.

Laser printable in sheet format (96 labels per sheet, 25 sheets per pack, 2,400 labels total) — print specimen ID, patient information, stain type, date, and any other required fields directly from a standard laser printer without special label software. Available in White, Blue, Green, Orange, Red, Yellow, and Rainbow (one sheet each of 5 colors) for color-coded specimen organization across departments, stain protocols, or collection periods.

Features and Benefits

• Polyester — Chemical Resistance to Xylene and Solvents: Polyester label material withstands xylene, alcohols, and other organic solvents used in standard histological processing, clearing, and coverslipping — labels remain adhered and legible through the full staining protocol.

• Autoclavable: Polyester labels survive standard autoclave cycles — use on slides processed in autoclaved solutions or in sterile tissue culture workflows.

• Laser Printable in Sheet Format: Standard sheet layout compatible with laser printers — print from any label software, Word, or Excel using standard 96-label sheet templates. No special printer required.

• 7/8 × 7/8 in — Sized for Microscope Slide Label Area: The 0.88 × 0.88 in square format fits the standard frosted area on the end of a 25 × 75 mm microscope slide without overhanging the slide edge.

• 2,400 Labels per Pack (25 Sheets × 96 Labels): High-volume pack for labs with ongoing slide preparation — 2,400 labels covers approximately 2,400 slides, appropriate for clinical labs, biobanks, and research facilities with continuous specimen preparation.

• 7 Color Options for Color-Coded Organization: White, Blue, Green, Orange, Red, Yellow, and Rainbow — use color coding to differentiate stain types, departments, collection dates, or specimen categories without relying on text alone.

Specifications

Laboratory Applications

• Histology and pathology labs — specimen labeling through full xylene-based staining protocols where paper labels would dissolve or detach

• Biobank and archival slide collections — laser-printed specimen IDs that remain legible and adhered through long-term storage and repeated handling

• Clinical microbiology — autoclave-compatible labels for slides processed in sterile conditions or autoclaved alongside equipment

• Multi-department color coding — using different label colors (or Rainbow packs) to differentiate specimens by department, stain protocol, or technician without additional annotation

Frequently Asked Questions

Are Tough-Tags compatible with inkjet printers?
Tough-Tags are laser printable — polyester label material is designed for laser toner fusion. Inkjet ink does not bond adequately to polyester and will smear or wash off. A laser printer is required.

What is the Rainbow pack (HEARNBW-3300)?
The Rainbow pack contains 25 sheets with 5 colors (Blue, Green, Orange, Red, Yellow) — approximately 5 sheets of each color, 480 labels per color, 2,400 total. It is priced slightly below the single-color packs ($70.50 vs $71.00) and is useful when moderate quantities of multiple colors are needed without purchasing 5 separate packs.

Do these labels fit the frosted area of all standard slides?
The 7/8 × 7/8 in (0.88 × 0.88 in) format fits the standard frosted label area on most 25 × 75 mm (1 × 3 in) microscope slides. The frosted area dimensions vary slightly by slide manufacturer — measure your slide frosted area before ordering if exact fit is critical.

Quality Assurance

Heathrow Scientific Tough-Tags are manufactured from polyester with adhesive formulated for chemical resistance to xylene, alcohols, and aqueous processing solutions. Autoclave compatibility is verified for standard 121°C steam cycles. Laser printability is confirmed for standard monochrome and color laser printers.
