Environmental educators in Pensacola are acquainting kids with water filtration in a new, hands-on way. Instead of a class turtle, these students are raising baby oysters. This program is sponsored by the Pensacola Bay Oyster Company and supports a local nonprofit, the Bream Fisherman Association, in its efforts to educate a new generation on marine wildlife preservation. Students contribute to the efforts to expand oyster populations in Pensacola Bay by purchasing and raising baby oysters (spat). It is a challenging and rewarding task, as baby oysters are not easily cared for. They are sensitive to salinity and other environmental changes, and must be maintained in the proper environment 2 feet below the water’s surface. The juvenile oyster cages must be periodically monitored and cleaned. Only after nine months of attention are the oysters mature enough to be placed in reefs or farms.

What is membrane preconditioning and why is it recommended to precondition new flat sheet or spiral wound membranes prior to use? Membrane preconditioning is a filtration step using deionized water as feed solution and is typically performed at a pressure equal to or higher than the anticipated testing pressure. During this process membrane pores are wetted and the membrane structure may go through compaction or swelling, affecting both the permeate flux and the rejection values. Preconditioning will help ensure that the membrane performs according to the specs provided by the manufacturer.

In the spirit of giving, we want to give thanks to all our customers and partners who have made 2017 a wonderful and memorable year. We look forward to continuing to foster these relationships in the years to come.

Cytoclear Glass Slides have been discontinued by the manufacturer due to lack of commercial interest, and are no longer available for purchase. These slides were previously used to enhance microscopic visualization with PCTE and PETE membrane filters, using a special light diffusing coating that significantly reduces the appearance of the pore edges by minimizing pore edge shadows.

Sterlitech has a new option to consider for your vent filter applications: hydrophobic polyester track-etch (PETE) membrane vent filters. The PETE membrane has been modified using a proprietary process to be rendered permanently hydrophobic. These filters may be considered for vent applications where PTFE or polyolefin membrane filters have been traditionally used. The PETE membrane filters have superior dimensional stability compared to unsupported PTFE membrane filters and have better thermal resistance than polyolefin membrane filters. Additionally, the PETE membrane filters typically have greater water entry pressures than similar pore size rated PTFE and polyolefin membrane filters while maintaining reasonable air flow rates. Finally, the inherently uniform pore structure resulting from the track-etch manufacturing process ensures that PETE membrane filters have exceptional lot to lot consistency.

These pilot skid systems are specifically designed for pilot testing of spiral wound membrane filters or small scale filtration processes. They offer more than 200 times the filtration surface available in standard bench-top filtration systems, allowing users to increase throughput and obtain results that translate for scale-up. Digital skids enable hands-free monitoring of process parameters and eliminate the need to manually record data.

Nobuto Blood Filter Strips are the bloodiest product in Sterlitech’s catalog; get some in time for Halloween sample testing! Made from high-purity cellulose fibers, these strips are structured for uniform sampling. Each strip holds approximately 0.1 mL of blood or 0.04 mL of serum.

When introducing a new control fluid to hydraulic systems, it is important to ensure that the new liquid or mixture is of equal or superior quality to the previous fluid. If the new mixture is incompatible, precipitate may form and result in an overall inferior fluid. This can speed up clogging or damage the system.

Leave it to Google to shine a light on our next generation of young scientists! As we start getting ready for the 2017 academic year, Sterlitech decided to look back at last year’s Google Science Fair awards. One group of clever kids caught our attention by winning the 2016 Scientific American Innovator Award with a subject near and dear to our hearts: filtration. They made filters from a unique source – waste Styrofoam packing!

Ariba, Coupa, SciQuest/Jaegger, and Oracle are just a handful of the increasingly popular purchasing platforms that enable subscribers to streamline purchasing processes between customers and vendors. These platforms often offer seamless integration into enterprise resource planning (ERP) systems, allowing for increased product visibility, expedient order processing, and timely invoicing. Part of this rising trend includes the use of PunchOut Catalogs in these platforms for eCommerce. Through PunchOut Catalog a buyer can have access a supplier's Web site from the buyer's own procurement application.
