What are Sterlitech Refurbished Test Skids?

Sterlitech has been collaborating with renowned global names in the filtration industry for the past decade. Our most recent partnership is with Rocker Scientific, a Taiwan-based manufacturer of filtration products with a global sales network, to offer a complete range of vacuum filtration equipment. Ultimately, this partnership will help us meet your laboratory needs. To know how, you may read our Press Release.

In this regard, the additional Sterlitech vacuum filtration products that we now offer are as follows:

Vacuum Pumps

Consisting of high-quality vacuum pumps for different applications,

The Amazon region in the province of Sucumbíos, Ecuador has been affected by millions or potentially billions of gallons of oily waste brought by the activities of the oil industry operating in the region since the early ‘70s.^[1] Maricela Granda, a 25-year-old environmental biotechnology engineer from Sucumbíos, hopes to contribute in securing water supply for the region with a new idea. She observed the structure of the banana pseudostem (“false trunk” of the banana plant that is cut down and discarded during harvest period) and investigated its potential use in purifying the oil-contaminated waters in her locality.^[2][3][4] Collaborating with universities, institutions, and like-minded youth, Ms. Granda developed a filter containing banana pseudostem intended to absorb hydrocarbon contaminants from water. Currently, her team is now working on a final design that will meet all water quality parameters in accordance to standards of the World Health Organization.^[4]

Pore size rating is among the key selection criteria for membrane filters as it indicates the extent of particle size (including microorganisms) that can effectively be retained in a filtration application. With its importance, manufacturers are compelled to provide pore size ratings as accurately as possible.

For such purpose, bacterial and particle challenge testing methods are used to accurately define pore sizes of membrane filters. However, these methods have proven to be destructive to the filters, require complex apparatus, and are arduous to perform.

The Bubble Point Test method substantially addresses the issues of the c
