Lab Labels & Marking

Low-Temperature & Waterproof · Write-On · Stays Put · Freezer and Bath Ready

Lab labels and marking consumables identify reagent bottles, sample tubes, glassware and storage vessels. Low-temperature waterproof labels keep their adhesion and legibility in freezers, water baths and damp conditions; used with a marker, they support sample traceability and record keeping as a basic part of lab organisation.

Product Description

1. Overview

Lab labels and marking consumables are basic tools for organising and tracing work. From sampling through storage, testing and retention, every step depends on clear, reliable identification, and whether a label survives low temperature, water and wear decides how trustworthy sample management is.

Common lab labels use a weather-treated face stock and adhesive. The face is usually water-resistant paper or a synthetic film, and the adhesive keeps its tack in cold and damp conditions. With a waterproof marker, writing resists removal in freezers, baths and even liquid nitrogen.

Selection comes down to environment and writing method. Freezer storage favours low-temperature labels; water baths and damp areas favour waterproof labels; frequent writing favours a write-on face. Colour coding helps identify by project, batch or hazard class at a glance.

🔬 Types & Features:
Low-temp and waterproof — works in freezers, baths and damp areas.
Firm hold — weather-resistant adhesive that will not lift over time.
Write-on — clear, rub-resistant writing with a waterproof marker.
Colour coding — separate projects, batches or grades by colour.

2. Key Parameters

  • Face stock: water-resistant paper or synthetic film
  • Adhesive: low-temperature and moisture resistant
  • Temperature: down to about -80°C depending on model
  • Writing: takes waterproof marker and ballpoint
  • Formats: rolls, pre-cut squares, many sizes
  • Colours: white, yellow, blue, red and more

3. Material & Workmanship

The face stock is usually water-resistant paper or synthetic film with a writable finish; the adhesive is a low-temperature, moisture-resistant formulation that keeps its tack when cold or damp. Rolls and pre-cut squares allow quick dispensing.

Handling tip: dry the surface before applying so oil and water films do not cut adhesion, and let the ink settle briefly before the vessel goes into a cold environment.

Choosing by environment

EnvironmentTypeNote

Water bathWaterproof labelResists moisture without lifting
Routine labellingWrite-on labelEasy to write, economical
Hazard markingIndicator labelBold and hard to remove
Micro samplesRound labelFollows the curve of small tubes

💡 Tips: Dry, then apply — a clean dry surface gives reliable adhesion.
Choose for cold — use low-temperature grades for freezer storage.
Let ink set — wait briefly after writing before going cold.
Manage by colour — use colours for projects and batches to speed recognition.

Operation & Maintenance

Operation Guide

How well a label sticks and how long the writing lasts depend on surface preparation and writing method. Typical steps follow.

03

Before Use

  • Dry the surface and remove oil and water films
  • Choose a label size to suit the vessel
  • Choose colour and type by application
  • Have a waterproof marker ready
  • For cold work, prepare low-temperature labels in advance
04

Procedure

  1. Write the required information, leaving room for number and date
  2. Wait briefly for the ink to start drying
  3. Peel the label without touching the adhesive
  4. Lay it down from one end and smooth it across to drive out air
  5. Press the edges down so the label is stuck all round
  6. Cover with clear tape for extra protection if needed
  7. Confirm it is firmly attached before cold or water-bath use
05

Cleaning & Care

  • Remove residual adhesive fully when changing labels
  • Clear adhesive with ethanol or a dedicated remover
  • Make sure the surface is clean and dry before reuse
  • Avoid repeated peel-and-stick, which weakens adhesion
  • Keep unused labels sealed and away from heat and damp

💡 Lab veteran tips: Write first — writing on a flat label is neater than on a curved surface.
Keep fingers off the glue — skin oil cuts adhesion badly.
Press the edges — a pressed edge will not lift and let water in.
Avoid the liquid line — keep labels off the level of the contents.

⚠️ Safety Notes

Surface prep

damp or oily surfaces make labels fall off

Complete info

include name, concentration and date

Stay legible

replace any label whose writing has faded

Hazard rules

warning labels should be bold and hard to remove

Do not
  • Avoid mix-ups: use clear colour differences between samples
