Laboratory liquid viewer for varying light conditions

In the pharmaceutical industry, you must inspect liquids in vials or ampoules for air bubbles or particulate contamination. Some of these particulates are difficult to detect with the naked eye and without special lighting. A simple and non-destructive testing technique with special lighting will offer an optimal solution to your lab environment to inspect glass containers for particles in liquids.

Detection of visible particulates in ampoules, vials, and transparent glass bottles

Apollo II Liquid Inspection Unit from The Adelphi is a simple unit designed to effectively detect particles in transparent glass bottles, vials, and ampoules. It is fully compliant with the European Pharmacopoeia Specification 2.9.20 & US Pharmacopoeia USP chapter 41 (1790), section 6.1. It has an adjustable lamp unit for comfortable working height. It comprises two energy-efficient LED lamps having light levels between 2,000 and 3,750 Lux. The intuitive assembly is operated by merely moving the container under inspection in front of both panels in a whirling motion. Consequently, light-colored particulates will be visible in front of the black panel, while dark-colored particulates will be visible in front of the white panel.

The unit has a removable diffuser for use with colored glass. Bulbs are rated to have a high service life of 50,000 hours, which would be more than 17 years when used in an 8-hour shift.
