SampleSafe seals are made of PP and are uniquely identified by a 9-digit serial number.

• Serial numbering for clear identification
• Stainless steel safety spring provides tamper protection

The seal ring (Ø 2 mm) is able to fit through small eyelets and slits. The tape is secured by a stainless steel spring with one-way tightening mechanism, which ensures a tamper-evident seal.
