Laboratory Labels
Sample identification in laboratories demands precision. A single mislabelled vial can invalidate months of research or compromise patient diagnostics. Laboratory labels from Positive ID Labels survive the conditions found in scientific environments – cold storage, autoclave sterilisation, and aggressive chemicals including xylene, acetone, and concentrated acids.
We supply both printed labels and complete in-house printing solutions. If your lab needs on-demand label production, we provide thermal transfer printers, blank label stock, and software to print variable data including barcodes whenever you need them. Call 01332 864895 to discuss your requirements with our team.
Why Standard Labels Fail in Laboratories
Ordinary adhesive labels cannot withstand laboratory conditions. They peel in freezers, dissolve in solvents, and become illegible after autoclaving. Paper labels absorb liquid spills, causing print to run and obscure critical sample information. Common adhesives fail when exposed to alcohol, acetone, or xylene used routinely in laboratory processing.
The consequences extend beyond inconvenience. In diagnostic pathology, a lost or swapped label means a patient sample cannot be correctly identified. In research, years of work can be invalidated by compromised sample traceability. Laboratory accreditation standards including ISO 15189, require robust identification throughout every process.
Chemical-Resistant Materials for Laboratory Labels
We use polyester and polypropylene face materials. These synthetic substrates resist penetration by acids, bases, alcohols, and organic solvents commonly used in laboratory procedures. Print stays legible, and adhesive maintains bond strength throughout the sample lifecycle.
Cold Storage Laboratory Labels
Frozen storage creates unique challenges. Standard labels become brittle and crack, and adhesives lose tack. Our freezer-grade formulations maintain flexibility through cold-chain conditions, suiting domestic and commercial freezer storage. For ultra-low temperature applications such as biobanking, we can source specialist materials – call to discuss your temperature range.
Autoclave-Resistant Labels
Steam sterilisation subjects labels to 121-134°C plus saturated steam conditions that destroy conventional materials. Our autoclave labels material and adhesives withstand repeated cycles without degradation. Print quality remains excellent and labels stay attached throughout decontamination – maintaining sample traceability through your sterilisation workflows.
Thermal Transfer Printing for Labs
Most laboratories use thermal transfer printers for on-demand label production. The technology creates permanent, chemical-resistant print using resin ribbons that bond to synthetic materials, withstanding chemical exposure, temperature extremes, and physical abrasion.
We supply blank label stock compatible with Brady, Zebra, and other major printer brands. Available in 25mm, 38mm, 44mm and 76mm core sizes, perforated or continuous, matched to your application requirements.
Barcode Quality for Laboratory Labels
Automated sample tracking depends on reliable barcode scanning. Our materials produce crisp barcodes that scan consistently after chemical exposure and temperature extremes. All common formats supported including Code 128, Code 39, DataMatrix, and QR codes used in laboratory information systems, with barcode quality meeting GS1 standards for scan grade. These can be printed on demand using labelling software or we can print variable data barcode labels to ease the processing of items through laboratory processing.
Laboratory Labels and LIMS Integration
Laboratory Information Management Systems require accurate tracking from collection through disposal. Barcode labels enable automated identification and reduce transcription errors. We help specify formats compatible with your LIMS requirements, ensuring seamless integration with your workflows.
Specimen Container Labels
Different container types need different solutions. Curved surfaces like tubes require aggressive adhesives and flexible materials that conform without wrinkling. Microscope slides need labels that survive xylene and alcohol washes during histological processing – see our dedicated slide labels page for details. Tissue cassettes must withstand paraffin embedding temperatures while maintaining adhesion. We supply sizes suited to common specimen containers, with custom sizes on request.
Colour-Coded Identification Systems
Many laboratories use colour coding for sample categorisation or workflow management. We can produce labels in multiple colours for these systems, with bright, consistent tones that remain stable through chemical exposure and temperature ranges – keeping your colour-coding effective throughout.
Complete Laboratory Labelling Solutions
Beyond labels, we supply complete systems for laboratory identification: thermal transfer printers from entry-level to industrial models, label design software, ribbons optimised for laboratory materials, and technical support to minimise downtime. This integrated approach gives you reliable identification without compatibility issues.

We’ve had a great experience working with this supplier, especially with Natalie - she is always very responsive, professional, and friendly. The pricing is highly competitive and the sales service has been excellent from start to finish. If I could offer one suggestion, it would be to improve the account and invoice management process. It would be really helpful if there were a system for clients to easily track their past orders and invoices in one place. Overall, very pleased with the service and look forward to continuing our collaboration.
Absolutely brilliant service from start to finish. The team are brilliant and the product was excellent quality and exactly what I wanted. Natalie is amazing as are her colleagues. Will definitely be a returning customer. Thank you
Ive used Positive ID Labelling Ltd for all our egg box labels for many years now. Natalie is always above and beyond helpful and the service is exceptionally fast and efficient.
I inadvertently ordered the incorrect label guns which was quickly sorted by Natalie. She was excellent, customer service at its best! Thank you once again
Frequently Asked Questions About Laboratory Labels
Will your labels survive freezer storage?
Yes. Our freezer-grade adhesives maintain bond strength and flexibility through cold-chain and commercial freezer conditions. For ultra-low temperature freezers used in biobanking, we can source specialist materials – call us to discuss your specific temperature range.
Can I print barcodes that scan after autoclaving?
Absolutely. Thermal transfer printing with resin ribbons creates barcodes that survive steam sterilisation cycles. Scan quality remains excellent after multiple autoclave exposures, ensuring your automated tracking systems continue to read every sample reliably. We are happy to supply samples for testing before committing to an order – and all products are guaranteed.
What’s the minimum order quantity for laboratory labels?
Blank label stock typically starts at one roll, allowing you to test materials before committing to larger quantities. Pre-printed labels may have higher minimums depending on customisation. Our digital presses keep short-run printed orders cost-effective even at low volumes.
Do you supply thermal printers as well as labels?
Yes. We provide thermal transfer printers, label design software, and ribbons as complete systems with guaranteed compatibility – eliminating trial-and-error testing. Technical support is included to ensure reliable operation in your environment.
Can laboratory labels be applied to already-frozen vials?
Certain low-temperature adhesives bond to chilled surfaces without requiring the sample to thaw. These specialist adhesives form secure bonds at sub-zero application temperatures. Discuss your workflow with our team to confirm the right material selection.
Are your laboratory labels suitable for GLP or GMP environments?
We supply materials appropriate for regulated laboratories and can provide certificates of conformity on request. Our ISO 9001 quality management system ensures consistent manufacturing standards across every production run.
