Sight glass

Use LJ Star’s sterile sight glass products for pharmaceutical and biotech processes where cleanliness, hygiene and efficient flow are critical.

Sight glasses and sight flow indicators are used widely in pharmaceutical and biotech applications, including on reactors, fermenters, mixers, WFI systems (water for injection systems), cryogenic vessels, tablet coaters, fluid bed dryers, centrifuges, and equipment for filtration, pilot systems, chromatography, and CIP/SIP skids and modules. Usually they are connected using stainless sanitary fittings.

LJ Star sight glasses and sight indicators meet the special concerns of pharmaceutical processing. Gaskets are FDA compliant (USP Class VI) and LJ Star’s METAGLAS products meet the standard for USP Type I glass, which is the glass most resistant to heat, chemical corrosion, and leaching. This means that our products have passed test procedures defined by USP29-661.

Also, METAGLAS fused sight glasses meet ASME BPE standards which require the seal point to be free of cracks, crevices and pits (SD-4.7.6 c). What’s more, LJ Star is the only company to offer a self-draining crevice-free bubble trap, specially designed for pharmaceutical applications.
