An overflow of liquid is unavoidable during vacuum filtration. However, this excess in liquid can potentially damage your vacuum pump’s motor and internal components as the overflow is sucked into the pump.
Sterlitech constantly aims to simplify your lab processes and provide innovative lab solutions, which is why we are proud to introduce a brand new line of filtration products featuring built-in Prote Overflow Protection.
Prote Overflow Protection prevents your vacuum pumps from damage caused by large amounts of liquid spilling out during your vacuum filtration applications. Not only does it protect your pump from liquid damage, but Prote Overflow Protection also prolongs the life of your vacuum pump.
Note: Vacuum pumps cannot be mounted sideways or upside down with the overflow protector.

Thin film track etched membranes, commonly referred to as polycarbonate (PCTE) and polyester (PET) filters, feature a unique pore structure and optical clarity unlike most filters. A complex, two step manufacturing process involving ion bombardment of the film followed by a chemical bath results in this attractive membrane exhibiting a smooth surface interrupted with the appearance of wrinkles, or rather waves, which may be concerning to first time users.
Waves are a structural artifact of the manufacturing process for these delicate yet durable membranes, made with very thin polymer films, less than half the thickness of a human hair. During the manufacturing process, long lengths of film are necessarily unwound and rewound into large rolls, multiple times. As a result of inhomogeneities in the material and slight fluctuations in thickness and tensile strength, waves occur while winding the material during the etching process. The more the roll is wound, the more intensive the

Knotty & Nice: New ways to treat textile wastewater
While holiday parties will be virtual this year, holiday sweaters in all their glittered, sometimes sequined, and knit glory are still making their annual appearance. Textile manufacturing is a multibillion dollar global industry, and novelty products like holiday sweaters comprise a significant market in the United States. We rely on textile products in our holiday sweaters, carpets, furniture, bedding, cars, hospitals, and more. In the United States alone, the textile market is projected to increase by 4.3% over the next seven years (1), which will lead to an increase in production waste as well. Wastewater from textile plants includes dyes, dispersants, and fixatives, or levelling agents, many of which are not biodegradable (2). In addition, dying is an inefficient process and high concentrations of textile dye never make it into the fabric. Removing the excess dye from waste water through various recycling methods

Sterlitech is pleased to announce the formal launch of the Sepa CFX Cross Flow Filtration Cell. The Sepa CFX is a member of the Developer family with an active membrane area of 140 cm2 (22 in2), the largest of bench-scale cells sold by Sterlitech.
This unit can be used at higher pressures than the previous Sepa CF, with a maximum pressure rating of 137 bar (2000 psig). The cell body ships complete with CFX plates, o-rings, bolts, and membrane. Additionally, this cell features torsion hinges and a gas spring for easy and safe operation.

Studying cell structures is the foundation of numerous fields in biology including health sciences, pharmacology, microbiology, and more. Traditional microscopic methods of observing structures within cells rely on dyes, fixatives, and/or artificial labels. The full effect that these extra components have on the functions of cell components is still unknown. For example, tacking a green fluorescent protein label to a drug receptor protein may interfere with the receptor binding site and decrease the effectiveness of the drug in the experimental cells (1). Micro-spectroscopy bypasses any interference from labels and dyes and is currently “the only technique for observing molecular activity in humans” (1).
The primary micro-spectroscopic methods currently being applied to cell biology are Raman spectroscopy and Infrared (IR) spectroscopy (2). These techniques rely on vibrational energy in chemical bonds. Raman spectroscopy is more versatile and can be used with a large range of wavelengths

Sewage and wastewater help in the fight against COVID-19
The World Health Organization declared SARS-CoV-2, known as COVID-19, a worldwide pandemic in March 2020. The world health organization has since reported 35.3 million cases and over 1 million deaths. Despite widespread efforts to social distance, wear masks, and reduce travel, infection rates keep climbing. Infectious disease researchers and public health officials are using new tools to get ahead of this deadly virus.
Aggressive community testing is the primary way for local and federal governments to obtain data on the spread of COVID-19. However, COVID-19 infections are unpredictable and testing limitations including individual costs, invasiveness, and reaching enough people pose challenges for surveilling community spread by testing alone. Recent research has discovered COVID-19 traces in sewage and wastewater, opening up a whole new avenue of testing strategies that may increase the ability to predict
