During the handling of powders and bulk solids, sonic or acoustic cleaners help to remove dry particulate buildup, which increases system efficiency, reduces downtime and maintenance costs, and helps to avoid structural fatigue and damage. This sonic horn produces a low-frequency, high-pressure sound wave using compressed air to cause a titanium diaphragm to flex. The sound wave is then magnified as it is emitted through the cleaner’s bell.
The Biotage Initator+ SP Wave enables researchers to synthesize peptides, peptidomimetics, and small molecules in quantities as low as 5 µmol using single- or multi-step procedures. It can function as a standalone peptide synthesizer, or it can easily be converted to a high-specification microwave-assisted organic synthesis (MAOS) system. It is semi-automated to reduce the consumption and waste of expensive reagents (which can occur in systems that require priming or that have large dead volumes). The programmable synthesis system includes a 10-in.
These expanded polytetrafluoro-ethylene (ePTFE) membranes housed in high-density polyethylene (HDPE) cartridge filters are available in three versions with retention ratings of 0.1 µm, 30 nm and 20 nm, and they can be used as drop-in replacements for existing filters. They are said to provide superior retention and be capable of achieving a 150–400% improvement in flow capability over the best filter technology currently available (with the same retention rating and flow performance). All non-PTFE components are made of HDPE to ensure low organic and metal ion extractables.
The Allegro 200L single-use mixer handles a wide range of liquid-liquid and solid-liquid mixing applications in biopharmaceutical processing, including compounding, formulation, buffer and media preparation, and pH/conductivity adjustment. With an impeller designed for low-shear, general-purpose mixing, it is well suited for difficult mixing tasks that involve dense powders or high-viscosity materials, or that require fast, repeatable performance. Clockwise and counterclockwise rotation enables up-flow and down-flow mixing.
The FlexFill assembly enables single-use biocontainer transfer. It provides a convenient way to aseptically transfer small bottled volumes of cell culture media, sera, reagents, supplements, buffers, and microcarriers to a bioreactor. It is delivered sterile, and is available in volumes from 500 mL to 6 L. Assemblies can be customized to support aseptic connectivity with a host of fitting and tubing options to allow for a seamless integration with the process.
Nunc roller bottles for adherent cell culture applications are now available in glycol-modified polyethylene terphthalate (PETG) and polystyrene (PS). InVitro PETG roller bottles withstand freezing and thawing and come with either a smooth or pleated internal surface. TufRol PS roller bottles feature vertical pleats for easy emptying, and are indented to allow single-handed manipulation. The TufRol bottles can be used with polystyrene Nunc T-flasks and cell factory systems to create an integrated bioprocess.
Aeration basins are an excellent way to reduce the nutrient load during water and waste-water treatment, but the energy costs of such systems can be high. The Instrumentation for Aeration Control Package provides all of the sensors and transmitters that water- and wastewater-treatment engineers need to gain better control over the efficiency and economics of the aeration basin in a single package. The instrumentation measures dissolved oxygen, suspended solids, temperature, air flowrates, air pressure, water level, ammonium, pH, nitrates, and thermal mass in the aeration basin.
The Hydraulic Fracturing Water Analysis Kit provides onsite results of key water analyses during oil-and-gas and enhanced-oil-recovery operations. It is useful for evaluating the quality of source water, fracturing fluid, flowback water, produced water, and drilling fluids. The kit comes in an easy-to-use, rugged, portable case, and includes a DR/890 colorimeter, HQ40d digital meter, a digital titrator, and reagents for such parameters as alkalinity, bacteria, barium, chloride, conductivity, hardness, iron, pH, and sulfate; additional parameters can be added as needed.
This company’s mobile water-treatment services use electro-coagulation technology to remove suspended solids and heavy metals from produced and flowback water obtained during oilfield operations. The treated water is suitable for reuse onsite for drilling or hydraulic fracturing, conserving freshwater use, reducing transportation and disposal costs, and enabling regulatory compliance. The mobile treatment train can be customized based on analysis of the unique characteristics of each well or other water source.
By protecting liquid chromatography/mass spectrometry (LCMS) columns from particulate build-up, the Acrodisc MS syringe filter reduces the frequency and cost of column replacement and enables more-consistent LCMS performance. The filter contains a water-wettable polytetrafluoroethylene membrane in a high-density polyethylene (HDPE) housing. These materials offer excellent chemical resistance, good particulate retention, and minimal protein adsorption, and they allow the filter to be used with either organic or aqueous solvents.
