View Ports

The strongest, most secure sanitary sight glass available, Viewport's mechanically pre-stressed windows are available in a sanitary clamp design for sight ports in processing applications or inline visual flow indicators.

Unlike some other sight glasses, Viewport sight glasses meet the USP Type 1 standard for pharmaceutical use.

Described as offering the optics of glass and the strength of steel, these glass elements provide a level of safety, and a useful service life, well beyond that provided by conventional tempered glass or plastic in sanitary service. Even at the most extreme temperatures (as high as 536&def;F) or in overpressure situations, sudden, total failure - that involving leakage or explosive shattering of the glass - essentially never occurs.

Approvals and Technical Data:
  • USP Class VI (tested to confirm biocompatibility)
  • BPE Compliant and TÜV Approved
  • Sight glass fused to metal conforming to DIN7079
  • Borosilicate glass to USP Type I and DIN7080
  • Standard surface finish of 10 Ra μ-in (0.25μm)
  • Material to ASTM/ASME, TÜV and DIN/EN standards
  • Certificate of Conformity to EN 10204-3.1B or 3.1A
  • Pressure Equipment Directive 97/23/EG
