Labels for bottles and Erlenmeyer flasks

Flexible labels for round bottles and Erlenmeyer flasks

Labeling larger containers seems simple, until you have to deal with condensation, daily cleaning, temperature shocks, and curved glass or plastic. Media bottles, Erlenmeyers, measuring cylinders, measuring cups… each has a specific labeling solution: from self-laminating polyester and xylene-resistant polyester to nylon cloth.

Our range

Water oplosbare Laboratoriumlabels I-Label Labels voor flessen en Erlenmeyers

Water-soluble labels

When you want to temporarily label bottles/Erlenmeyer flasks or glassware and remove the labels quickly and cleanly afterwards. This material dissolves completely in warm water and leaves no adhesive residue.

  • Solved within 30 seconds, without adhesive residue
  • Print-on-demand thermal transfer
  • Quick to apply with pressure-sensitive adhesive
Incubator Laboratoriumlabels I-Label Labels voor flessen en Erlenmeyers

Polypropylene labels

For bottles and Erlenmeyer flasks used in demanding environments (long-term storage, hot water baths, autoclaves, etc.), polypropylene labels with permanent acrylic adhesive are a strong all-round solution.

  • Matte white polypropylene, suitable for thermal transfer printing
  • Gebruikstemperatuur – 80°C tot +70 °C
Labels voor vials, flesjes en buisjes Sterilisatieindicatie

Sterilization indication labels

These labels provide users with proof of sterilization. They are ideal for a wide range of laboratory processes, including sample tracking, inventory management, and identification of glassware or trays.

  • Color change as a process indicator (autoclave)
  • Useful for status labeling
  • Vermindert misverstanden en dubbele verwerking

Also indispensable for labeling in the laboratory

Labels op maat afmeting en vorm

Custom labels

If a standard permanent adhesive is not sufficient, the white polyester EXTRA permanent labels offer the solution. Thanks to their ultra-aggressive adhesive, these labels also adhere to difficult surfaces such as textured, rough, or low-energy substrates.

Labels voor vials, flesjes en buisjes Kleurcodering

Labels for vials

Labels on rolls for LC/GC headspace, blood tubes, falcon tubes, EPT tubes, cryovials, and vials.
Designed to remain adhesive in cold conditions, condensation, cleaning, and solvents.

I-Label labelprinters (Vial Label printer)

I-Label Vial Label Printer

Our Vial Label Printer is designed to label vials/tubes efficiently and professionally. The semi-automatic system means you don’t have to stick the labels on yourself. This speeds up your production process and saves you time.

Frequently asked questions about laboratory labels

Why choose I-Label for my laboratory identification?2026-08-27T15:33:35+02:00

I-Label specialises in laboratory identification: from cryogenic storage to autoclave sterilisation and chemically aggressive environments. Unlike a general label supplier, I-Label offers a comprehensive range tailored to specific applications, always using the right materials. What’s more, you always receive the combination of label, ink ribbon, printer and software as a single, coordinated package, complete with personalised advice and free samples to test in your own environment before you place your order. What’s more, you can also make use of the I-Label Test Centre.

What is the most common reason why a freezer label comes off?2026-07-14T11:16:06+02:00

The most common reason a freezer label comes loose is usually condensation or ice between the label and the surface during application, or an application temperature that is too low for proper adhesion. Even a label that can withstand -196°C in storage often needs to be applied at a higher temperature to develop its full adhesive strength. Of course, we also have labels that can be applied to already frozen materials. To determine which label is best suited for your application, we always recommend testing a few materials beforehand.

Are labels available in different colors?2026-04-01T14:11:15+02:00

Yes, for clear color-coding, we offer labels in clear, white, and yellow. This makes it easier to organize and identify samples.

Are your labels suitable for different laboratory applications?2026-03-06T10:26:59+01:00

Yes, our labels are specifically designed for a variety of applications such as labeling lab tubes, circuit boards, components and warehouse storage. With color coding and size labels, you can improve your laboratory organization.

Does a barcode remain scannable after several freeze-thaw cycles?2026-07-14T12:29:59+02:00

When the correct material is used, the text remains legible and the barcode remains scannable. It is not only the adhesive that is important, but also the combination with the correct ink ribbon, so that the print itself remains resistant to friction, condensation and repeated temperature changes.

Can labels withstand freezing and refrigeration conditions?2026-04-01T14:10:45+02:00

Our medical labels remain adhered and legible, even at sub-zero temperatures or in refrigeration systems. Ideal for samples that need to be stored for long periods.

What are the advantages of lab labels on a roll?2026-02-26T13:26:23+01:00

Lab labels on rolls are ideal for use in label printers because they can produce large quantities of labels efficiently. We offer thermal labels for fast printing and white labels for a professional look.

Can labels be applied to small surfaces?2026-09-03T13:54:39+02:00

Yes, I-Label supplies labels specifically tailored for small surfaces, ranging from cryo straws with a diameter of 0.25 mm to component labels and cable IDs. For these applications, we select thin, flexible materials that wrap neatly around a small surface without coming loose, and we print using 600 dpi printers to ensure that microtext and small barcodes remain sharp and scannable. Both the dimensions and the roll configuration can be fully customised, right down to the smallest laboratory or product identification.

What types of barcode label printers do you offer?2026-08-27T15:58:16+02:00

I-Label offers five main categories of label printers. The Brady label printers form the core of the range, with separate sub-categories for industrial, portable, safety signage and automatic labelling. In addition, we also supply our own I-Label label printers, Epson colour printers for full-colour labels, and semi– and fully-automatic systems for those who wish to eliminate manual application. Which type is best suited depends on your volume, mobility and application.

Why should I use a barcode label printer for my laboratory processes?2026-09-01T13:13:21+02:00

A barcode label printer makes every sample, tube or protocol uniquely and accurately traceable; something that is not achievable with handwritten labels or a standard office printer. You can link barcodes (1D or 2D/DataMatrix) to your LIMS or ERP system, so that a single scan retrieves the complete sample history: who took the sample, what treatment it underwent and where it is located. This eliminates manual transcription errors, speeds up batch processing and supports compliance requirements such as ISO or GLP, where full traceability is mandatory. I-Label printers also print these barcodes onto laboratory-specific materials that are resistant to freezing, autoclaving and chemical conditions, ensuring the code remains legible throughout the entire process.

Do laboratory labels remain legible when chemicals are used?2026-09-01T13:35:14+02:00

Yes. Our laboratory labels are resistant to solvents, alcohol, and other chemicals. This ensures reliable identification, even after heavy use.
