Overview

Precellys® 24 Touch is the ideal lab homogenizer to prepare any kind of biological sample, from the softest to the hardest, regardless of its origin (animal tissues,plant tissues, microorganisms…). It can treat up to 24 samples at a time and has been validated on more than 1,500 different samples: from brain, muscle and heart samples, to very hard material such as bones, hair and seeds. The intuitive touchscreen interface of Precellys® 24 Touch makes it really easy to use. Thanks to its exclusive vacuum-based tube locking system and its specific design, Precellys® 24 Touch is compliant with safety requirements of the harshest lab environments, such as BSL3. With its powerful figure-8 multi-directional motion, Precellys® 24 Touch provides high energy to the beads contained in the tubes, allowing the homogenization of the samples in a few seconds (~30 sec) at speeds ranging from 4000 to 6800 rpm. Samples can then be processed for further analysis amongst a wide variety of techniques dedicated to DNA/RNA (PCR, electrophoresis, NGS, chips, etc), protein (blotting, mass spectrometry, etc.), or metabolites analyses (chromatography, etc.).

The Precellys utilizes a figure-8, multi-directional motion which conveys a very high kinetic energy to the beads, causing intense collisions which break apart samples.  In many homogenizers, mechanical impacts between beads or between beads and the sample can generate heat. With the Precellys 24, the homogenization process is so fast that the temperature does not reach denaturation levels.

The Precellys has established protocols and various consumables for the processing of soft tissues, hard tissues, or microorganisms.  Users can simply change the speed and beads to accommodate a number of applications, such as:

  • Dry grinding
  • Micronisation
  • Homogenization from fresh or snap-frozen tissues
  • Lysis of micro-organisms
  • Dissociation of living bacteria

The Precellys has been designed specifically for biological sample preparation.  Processing space is sealed off from the mechanical parts preventing any inside contamination, and individual sealed tubes prevent cross contamination between samples.  Once your protocol is validated, the sample preparation process remains exactly the same with no variability.  The Precellys was specifically developed and designed to be used in a BSL3 laboratory under high throughput conditions: 50 to 100 runs per day.

A 1-year warranty is standard with the Precellys.  Extended 2-year or 3-year warranties are optional.  For each additional year of warranty, a maintenance kit is provided which includes 2 vacuum joints, 1 anti-rotation tubing kit, and 1 containment seal.

Want the power but don't need the throughput?  Take a look at the inexpensive Minilys.  Want even more power and the flexibility to accommodate larger samples?  Check out the Precellys Evolution.

FAQ

What are the primary differences between the Precellys 24 and the Precellys Evolution?

There are three main differences:

  1. ​Power. The Precellys Evolution has almost 50% higher max RPM than the Precellys 24.
  2. Flexibility with regards to sample size. The Precellys 24 holds 24x 2ml tubes. The Precellys Evolution also comes with an adapter that does the same, but there are additional, optional adapters that hold either 12x 7 ml tubes or 6x 15 ml tubes, allowing processing of larger samples.
  3. If you're interested in keeping samples cool, the Cryolys cooling unit is much better for the Precellys Evolution. The Cryolys for the Precellys 24 is a standalone item which takes up about an equivalent amount of bench space to the Precellys 24 and requires a compressed air connection (or house pressurized air). The Cryolys for the Precellys Evolution is a relatively small "cap"-like device which sits on top of the Precellys Evolution so it doesn't take up any additional bench space and it does not require an air hookup.

 ... and of course there's the cost difference.

 

What are the safety features of the Precellys 24 which make it suitable for BSL-3 labs?

  1. Top and pressure alarm: If the lid is not securely closed or the blocking plate is not placed correctly on the tube holder to lock the samples in place, the unit will not start the run.
  2. Compatibility with vaporized hydrogen peroxide decontamination (see picture below). Vaporized H2O2 can be used to decontaminate the unit in case of tube breakage.
  3. Containment seal which isolates the homogenization chamber from both the external environment and the internal mechanical parts.

One of the most poignant books I have read in a long time.
Format: Paperback
One of the most poignant books I have read in a long time. “Southern communities, lawmakers, and courts recognized slave-owning women as individuals able to acquire and exercise mastery over enslaved people, s is evident from laws passed throughout the South. Laws dating back to the colonial period routinely recognized the mistresses owned enslaved people in their own right, and these same laws acknowledged the fact that these women were capable of exercising mastery over the enslaved people they owned.” Stephanie E. Jones - Rogers. They were referred to as Southern Belles’. Revered for their ladylike daintiness. But… there was nothing dainty about their dealings for they too, owned human property. These white southern mistresses were heavily involved and often owned more property than their male counterparts even being the breadwinners. These women were barbaric and wore the crown of cruelty. Dr. Rogers gave the enslaved a voice in this text – allowing our ancestors to share with us their story and experiences under the thumb of white mistresses. This text uncovers the extent of the involvement that white women had with slave ownership. There was discord in marriages due to white women struggles to maintain control of their financial gains of human property. These women utilized the judicial system to protect their pecuniary interests. The parents of these white girls/women bequeathed slaves to white females i.e. as young as newborns – which leads us to mistresses in the making – that is the education of young white women of the mastery of slave ownership. My heart broke as I was able to envision the accounts of atrocities inflicted upon our ancestors. Our people were raped and forced into being breeders and wet nurses to ensure the livelihood of these white mistresses and their families. The evidence is insurmountable in all the ways slave-owning women invested in, and profited from their financial ties to American slavery and its marketplace. Most importantly, there was testimony from formerly enslaved people of their experiences within slavery. This text is a mandatory read for all and in my opinion, must be included as part of the curriculum in schools.

Slave Trade was not only a White Man's Affair
Format: Kindle
The book is an excellent read particularly in today's climate. Why 53% of white women would put a vile man in office is explained in the pages of this book. White women held positions of power in the America slave trade, a fact overlooked in history. These southern bell's represented as the gold standard of woman hood in the antebellum south were anything but, and they for the most part showed as much, business savvy as down right cruelty in the slave trade. They benefited in every conceivable way from this free labor market. They were no advocates for the kind humane treatment of slaves. In many cases they were as vicious as their counterpart and just as committed to a keeping Blacks marred in the system of bondage. They are in most cases depicted as silent partners and where that might be the case many white women had full command and knowledge of the value of a slave they invested in and they wanted a hefty return. In fact they used every means on the table to keep these black, men, women and children bound to their wealth creation. These co-conspirators had more than a hand in the cookie jar, they enjoyed the power and did not hesitate to support the maintenance of this inhumane institution.

Excellent book, not only for lawyers or law students
To begin with, I am neither a lawyer, a law student, nor even a prospective law student. I am, however, someone who has always been interested in the law, primarily for two reasons. First, the law is the principal formal means a society uses to try to resolve conflict among the society's members. Second, and closely related to the first reason, the sum shape, both of content and procedure of the law, is an expression of exactly what a society's values are and the goals a society sets for itself or the standards by which it ideally wishes to be judged. I found this book to be excellent, informative, well written, and even at parts entertaining. Although meant as a guide for law students to use to prepare for the strenuous exams that are associated with each course they will take in law school, the book provides much, much more, and hence my belief that it can profitably be read by a far larger readership than its ostensible audience. One of the key elements stressed throughout, and exemplified by numerous enlightening examples, is that there usually is no one correct answer to any given legal question. Arguments can be made on at least two sides of any matter based upon, for example, a "plain reading" of the text of a relevant law and the reasonably understandable intent of those who made the law (e.g., a legislature). The authors bring out clearly such sources of legal precedent as laws, government regulations, individual case law decisions by judges, common law, government policy, and specific codes (e.g., the Uniform Commercial Code, or UCC) and show how differing results to a case can readily come about based upon arguments using the different sources to bolster respective cases. In reality, although by minimal definition a book designed, as said above, to prepare for the taking of law school tests, the book actually also is a good guideline on how to think (not necessarily what to think) about many larger issues in society, including politics and policy issues of all sorts. Finally, the first two thirds of the book discuss ways to think about the wide range of questions that can be posed to aspiring lawyers and introduces the reader to understanding such distinctions as "forks in the law" and "forks in the facts" (a quite useful distinction to keep in mind). The final part of the book provides solid test taking strategies that are applicable to a wide range of academic testing (e.g., answer the question the professor actually asked and avoid wasting time or effort on ancillary matters not really germane to helping to resolve the issue.) Although some of these may seem obvious once read, the tips are the type of thing that, under pressure of exams, many students often forget to apply. In sum, I highly recommend this book to those interested in life in the modern world.

Must read for 1L or Incoming Law Student! So helpful!!!
Format: Paperback
Any 1L or incoming law student needs to read this book! So, I took the BARBI Law Preview before law school began to get an overview of what law school was like and a heads up on how to do things. During this program I had read just two chapters of the book- and these two chapters alone put me in a crucial mind frame to understand the importance of what your professors are looking for. It is not just about distinguishing the right issues and facts, because there is truly no such thing, but distinguishing both sides of an issue, and of course you have to read the book to get more info, but I feel like it has helped me understand what success sounds like in exams. I am only going into my third week of 1L, but I can tell the book has given me a leg up. I recommend that you read this book before you start, or in the first two weeks (though you'll be burdened with a lot of reading then- so before is best) so you can get into the mindset, instead of doing it right before exams and feeling like you have to rewire your brain to everything you thought you understood. I guess I'll have to update you guys once I see my exams, but so far so good!

Must-Have for Law Students
Format: Paperback
This is a good book. A lot of the trouble with law school exams is law professors are notoriously bad teachers, and these bad teachers write bad exams. Granted, this is a worst-case scenario, but if you've been to law school for more than one semester, there's a good chance that at least one of your professors has utterly bamboozled you into how he/she wants the final written. So what this book does is give you something of a blueprint and a method of examining fact patterns and exploring the question(s) so that you can simply go into the exam and take it without much fear. Where the book fails to be of help though, is with the IRAC method. I wholeheartedly agree that IRAC is a too-constrictive method of writing that tends to inhibit most students from really expressing what they know. Law professors largely want a mechanical recitation of rules followed by mechanical analysis, so law students spend hours and hours memorizing rules with the ultimate purpose of using them in an IRAC format. It's absurd, but that's the way it is. And this book simply dismisses the fact that lazy law professors love IRAC for the fact that it gives them a template from which they can read and score exams quickly. But still, you can construct an IRAC using this method, it just doesn't lend itself seamlessly to it, which is pathetic--not with respect to GTM, but to the teaching and testing methods used by professors. If you don't believe me, and if you haven't already done so, go look at model bar answers from your state and see if they employ a rigid IRAC formula. They don't. And so to me, that's what this book was good for--being able to write bar exam quality answers that leave room for a different writing styles and methods of analysis. If you're just starting law school, buy this book. If you're already in and still struggling, buy this book. If you're the king or queen of fastidious, multiple, anally retentive headers on your exams, read this book and go look at bar answers.
