The Tamper-Clear Syringe Seal provides a tamper-evident seal with clear visibility of syringe graduations. It’s easily applied over the syringe cap and maintains the integrity of the medication and packaging, even when refrigerated. Once removed, the seal can’t be reapplied. Removing the syringe cap destroys the seal. Designed to withstand freezing temperatures down to -20 degrees Centigrade, Steri-Tamp’s powerful adhesive seal has been shown to be over three times stronger than others on the market, and it provides a 100% sterile barrier.
