Sterilisation Indicator Labels & Tape

Gamma Radiation for Sterilisation

Gamma rays are high energy electromagnetic waves which are only stopped by thick lead. This means they can easily pass through medical equipment, such as syringes. As gamma rays pass through the packaging they will kill living tissue such as viruses and bacteria. As long as the equipment remains in a sealed plastic pack it will remain free of viruses and bacteria.

Our Stericator Gamma sterilisation indicator labels and tape can be used as qualitative process indicators to ensure full and proper sterilisation has occurred.


• Consistent colour change on a uniform sterilisation indicator label from yellow/orange to red

• Each sterilisation indicator label batch is independently validated in a recognised Gamma plant

• The chemistry and product ranges have been completely developed in house for our sterilisation indicator labels and tapes

• Sterilisation indicator labels are supplied as 12.5mm with self adhesive backing

Also unlike many of the competitive sterilisation indicator labels and tapes, Stericator Gamma contains no heavy metals.

The Stericator-Gamma Indicator Labels are process indicators to differentiate irradiated and non irradiated products.
The Stericator-Gamma indicator labels are sensitive to the Gamma radiation process and should be used as an indicator, not as a dosimeter.


Stericator sterilisation indicator labels are self adhesive, 12mm diameter, 5000 per reel, also available in other formats or as a tape.

Order Size

Flexible order quantities are available, in multiples of 5000 sterisation indicator labels.


Lead Time

Gamma Sterilisation Indicator labels are dispatched within 48 hours from receipt of order.

Technical Specification

Sterilisation indicator labels are for use as a process indicator (Class 1), for the sterilisation of packs by gamma irradiation. There is a noticeable colour change at 5kGy with increased colour density up to 100kGy.

Shelf Life and Storage

Stericator-Gamma Sterilisation Indicator Labels have a shelf life of 24 months from the date of manufacture prior to sterilisation, provided they are stored in ambient conditions below 20°C and 50% R.H. and in the dark.
