AcroPrep 24-Well Filter Plates with 1K Omega membrane are optimized for ultrafiltration applications, offering the rapid and efficient separation of biomolecules.

Ultrafiltration is a membrane separation technique used to separate extremely small particles and dissolved molecules in fluids. The primary basis for separation is molecular size, although other factors such as molecular shape and charge can also play a role. Molecules larger than the membrane pores will be retained at the surface of the membrane and concentrated during the ultrafiltration process. Ultrafiltration can be used in a variety of applications including size exclusion, PCR clean-up, nucleic acid purification and protein separation.

The Pall Omega membrane is a polyethersulfone membrane specifically modified to minimize protein and nucleic acid binding. The low binding nature of the membrane offers numerous benefits, including high recoveries of low concentrations of biomolecules and less surface fouling, which can cause retention performance to decay. The Omega ultrafiltration membrane is available in Pall’s range of centrifugal devices as well as AcroPrep 24, 96 and 384-well filter plates.

AcropPrep 24-well filter plates allow up to 7 mL of sample to be filtered in each well, eliminating the need to process samples with other labor intense methods and resulting in time savings. Researchers can confidently incorporate Pall 24-well filter plates into their workflow without costly and time-consuming membrane evaluations.

AcroPrep filter plates are constructed from chemically resistant and biologically inert polypropylene which means that the plates themselves are low in binding to nucleic acids and proteins. A patented design and unique sealing mechanism is used to individually seal filter media into each well of the plate, preventing crosstalk and the possibility of cross contamination from one well to another. The filter plates feature a smooth well design that provides consistency in filtration times, as well as efficient sample. All plates come with a receiver plate and a lid.

AcroPrep filter plates are designed to meet the stringent requirements for high throughput applications and are manufactured in accordance with SBS guidelines, allowing plates to be run in manual, semi-automated, and automated processes. A rigid single piece construction prevents plates from flexing or jamming in robotic systems, whilst barcode labeling allows for easy sample tracking and identification.

Awful textbook
Format: Paperback
I think this is the most poorly written textbook I have ever used. The JBL site for this book is garbage. So many spelling mistakes and publishing errors. Rent this book do not buy, your program will most likely not keep this crap around for long.

An Informative Introduction Based on Current Academic Studies of Western Esotericism
Format: Hardcover
This introductory text is the fruit of a fairly new field of recognized academic studies which developed as a result of the pioneering literary efforts of scholars such as D. P. Walker (1914 - 1985) and Frances A. Yates (1899 - 1981) who took the subject of Western esotericism seriously rather than denigrate it as an area filled with superstition and irrationalism as many earlier scholars in different specialized fields had done. Other scholars of esotericism who have contributed to this growing field include but are not limited to Henry Corbin, Francois Secret, Antoine Faivre, Arthur Versluis, Joscelyn Godwin, and Wouter Hanegraaff, the last being the senior editor of the landmark Dictionary of Gnosis and Western Esotericism (2005), a collaborative effort by many scholars. Goodrick-Clarke is also a recognized scholar in this field and introduces it to the reader in his own introduction which also addresses the question of how esotericism is defined by those dedicated to studying it. As clarified in the introduction, Western esotericism is rooted in the Hellenistic philosophy of classical paganism as expressed in Alexandrian Hermeticism, Neoplatonism, and Gnosticism which have syncretized with the three Abrahamic religions of Judaism, Christianity and Islam, leaving vital traces within each. Through the Italian Renaissance, a Hermetic revival occurred as a result of the rediscovery of ancient texts which further resulted in the development of magic, astrology, alchemy, and Cabala through prominent individuals such as Marcilio Ficino, Pico della Mirandola, Johannes Reuchlin, Johann Trithemius, Henry Cornelius Agrippa, John Dee, and Paracelsus, each given significant attention. The development of German Naturphilosophie, Christian theosophy through Jacob Boehme and his followers (such as Gichtel, Pordage and Law), and Pietism are also covered before thoroughly introducing us to Rosicrucianism in the early 17th century, high-grade Freemasonry and Illuminism in the 18th century, and the ideas and practices of Emanuel Swedenborg and Franz Anton Mesmer which significantly impacted esotericism. Within the context of Rosicrucianism, the content of the manifestos are discussed along with Johann Valentin Andreae and the Tubingen Circle; in England, Michael Maier, Robert Fludd, and Comenius and the Origins of the Royal Society are covered. The impact of Rosicrucianism and theosophy on Freemasonry are explored as well as the following types of Freemasonry: "Scottish" and Chivalric, German Templar, and Egyptian. Within the context of Freemasonry and Illuminism, the following are also discussed: Martines de Pasqually and the Elect Coens, Louis Claude de Saint-Martin, Martinesism, Martinism, Willermozism, The Illumines of Avignon, and Count Cagliostro. Not only are the ideas of Swedenborg and Mesmer presented but also how they contributed to spiritualism and healing movements in the 19th century, including the United States which birthed Andrew Jackson Davis as the main theologian for spiritualism; Phineas Parkhurst Quimby, Warren Felt Evans and others who developed the New Thought Movement; and Mary Baker Eddy who founded Christian Science. A separate chapter is dedicated to ritual magic from 1850 to the present. Within this chapter, one is introduced to Eliphas Levi and the French Occult Revival, the Hermetic Order of the Golden Dawn and its members, and special attention is given to the contributions of A. E. Waite, Aleister Crowley and Thelemic magick, and Dion Fortune and the Inner Light. I was, however, disappointed to see the section on Crowley end with the following: "Gerald Gardner (1884 - 1964), the founder of modern witchcraft, introduced Crowleyan magick into the neopagan Wiccan movement." For a better understanding of the influential role of Crowley and ritual magic, including the grimoires, on Wiccan practices, I recommend Wicca: Magickal Beginnings (2008) by Sorita d'Este and David Rankine. Helena Blavatsky and her Theosophical Society are given a separate chapter which expounds on her influences, travels, developing doctrines, and legacy. The last chapter titled "Modern Esotericism and New Paradigms" discusses theosophical heirs such as Annie Besant, Charles W. Leadbeater, and Rudolph Steiner (who developed his own religious system called "Anthroposophy"). It also has a section on Fourth Way Groups, introducing Gurdjieff and Ouspensky. Additionally, it covers the scientization of esotericism, New Age science, and Carl Jung's influence on esotericism. One individual I would have liked to see introduced within the context of Steiner is Valentin Tomberg who anonymously wrote Meditations on the Tarot: A Journey into Christian Hermeticism which is recognized by some, including esoteric scholar Antoine Faivre, as a masterpiece of 20th century esoteric/mystical literature. Goodrick-Clarke's book not only includes valuable footnotes and recommendations for further reading for each chapter, but also includes a helpful index as well as over 30 illustrations comprised of portraits, diagrams, plates, charts and other relevant pictures to supplement the text. This historical introduction to Western esotericism deserves wide readership.
