14-by-40 Liqui-Cel Membrane Contactor

The 14-by-40 Liqui-Cel Membrane Contactor extends the capacity of the Liqui-Cel family of deaeration products from 400 gpm to 550 gpm (125 m3). It consists of a polyvinyl chloride (PVC) housing containing polypropylene hollow-fiber membranes knitted into an array that is wound around a distribution tube with a central baffle. During operation, the liquid flows over the outside of the hollow fibers, and the baffle directs the liquid radially across the array. A stripping gas or vacuum, either separately or in combination, is applied inside the hollow fibers.

Spinner series of jet-spray nozzles

A recent redesign has made the Spinner series of jet-spray nozzles more hygienic and more effective at cleaning tanks, drums, barrels, kegs, and ductwork. They are designed for cleaning small to mid-sized tanks, and easily fit into the narrow port holes of such vessels. The two standard models are the Micro-Spinner (for tanks up to 4 ft in dia., with a 1-in.-dia. orifice) and the Mini-Spinner (for tanks that are 4–9 ft in dia., with a 2-in.-dia. orifice).

HPR Series lab-scale reactors

The HPR Series lab-scale reactors are said to be ideal for studying catalytic, polymerization, hydrogenation, oxidation, isomerization, and dehydrogenation reactions, in applications ranging from high-pressure chemical syntheses to process development. The stirred reactors have a magnetically coupled impeller for optimal mixing. They range in size from 50 mL to 4 L, and may be operated at conditions up to 10,000 psi and 350°C. All sizes are supplied as ready-to-use instruments requiring only utility connections prior to operation.

Model HSM-100SK-1 multi-purpose laboratory mixer

The Model HSM-100SK-1 multi-purpose laboratory mixer is a bench-top unit that comes with interchangeable mixing attachments, including batch and inline rotor/stator sets, and disperser blades and propellers of various sizes. Depending on the attachment, the mixer can handle formulations with viscosities as high as 50,000 cP. It features a variable-frequency drive that provides speed control from 500 to 10,000 rpm with ±1% accuracy. With 16 in. of clearance under the mixing attachment and 12 in. of distance between the feet at the base, the mixer can be used with vessels of various sizes.

COM-1700 potentiometric titrator

The COM-1700 potentiometric titrator allows users to carry out up to four different types of titrations — including potentiometric, photometric, polarization, and conductometric titrations — in parallel. Its buret design allows for the quick, automatic exchange of reagents. The standard buret size is 20 mL, and optional buret sizes of 1, 5, 10, and 50 mL are available. Each titration station can control up to 10 burets. The new sample changer accommodates a wide selection of test tubes, beakers, and conical flasks.

MWF-SGSP-OS weigh belt feeder

The MWF-SGSP-OS ultra-sanitary open-construction weigh belt feeder has an all-stainless-steel construction, so it is well suited for processing foods and other materials where cleanability is essential. The feeder can provide closed-loop gravimetric control of the material feed rate, or it can be used in an open-loop configuration for precise conveying-rate output and totalization of an uncontrolled or intermittent material supply.

Sonic Horn

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.

Biotage Initator+ SP Wave

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.

Cartridge Filters

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.

Allegro 200L single-use mixer

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.
