  1. Choosing a Pump for your Fluid Handling Application
    October 04, 2015
    The type of pump you choose for your fluid handling will largely depend on your laboratory application. In this article, we will compare the popular pump types. Peristaltic Pumps A peristaltic pump has a series of rollers that rotate around the edge of the pump head. A flexible tubing is threaded around the rollers and pressed up tight next to them, pinching the tubing where it contacts a roller. As the rollers rotate around the head, the fluid in the tubing moves from the input to the output. The rate of head rotation and the size of the tubing determine the volume of fluid that can be pumped. The volume that can be pumped is limited only by the volume of the input source. Syringe Pumps A syringe pump consists of a syringe attached to a motor driven pusher block
  2. NanoFil for Sub-Microliter Injection in Small Animal Research
    June 25, 2015
    Are you looking for a unique, low-volume syringe that holds metal tips (with needles as small as 36 gauge) as well as glass or quartz tubing? NanoFil is the answer. Necessity is the mother of invention” This quote from the dialogue Republic by ancient Greek philosopher Plato, could be considered one of the mantras of scientific research and product development. Many specialized products used in research were developed out of a specific need that was not already addressed in the market place. We often use these products without even thinking about their history, their development, or the imagination of the person who invented them. WPI's NanoFil
  3. Application Kits for Use with the NanoFil for Microinjection
    June 25, 2015
      Application kits are specially designed for eye research for injecting retinal pigment epithelium (RPE) and for intraocular (IO) injections. In addition, these kits may be used for brain injection in mice. They need to be used with a NanoFil syringe and UMPIII to achieve accurate, repetitive and oil-free injection in the submicroliter range. Each kit includes two pieces of Silflex tubing (one for a spare), a holder assembly, spare gaskets, and an assortment of four tips - blunt for the RPE kit and beveled tips for the IO kit. Each kit comes with one each of 33, 34, 35 and 36 gauge tips so that first time users can find the best size for their application.The Silflex tubing is the most critical component of the kit. This 35cm long, flexible tubing has a very precise outer
  4. When a Bigger Bolus is Better
    June 12, 2015
    First, let's consider volumes. A milliliter (mL) is one thousandth the volume of a liter (L) or 10-3L A microliter (µL) is one thousandth the volume of a mL (10-6L) A nanoliter (nL) is one thousandth the volume of a µL (10-9L) A picoliter (pL) is one thousandth the volume of a nL (10-12L) This is graphically represented at the right. Notice that the mL is one trillion times larger than the picoliter. The table (right) shows that the side of a cube with a volume of 1mL is 1cm long. Likewise, the side of a cube with a volume of 1pL is 10µm long. Just for comparison, it shows that the diameter of a sphere with a volume of 1mL is 1.24cm, and the volume of a sphere with a volume of 1pL is 12.4µm. With these volume comparisons in
  5. Using WPI's PUL-1000 Micropipette Puller
    March 06, 2015
    World Precision Instruments' PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes used in intracellular recording, microperfusion and microinjection. It offers programmable sequences of up to four steps with complete control over the heating, force, movement and cooling time. This allows graduated cycles for a variety of applications. PUL-1000 can produce pipettes with tip diameters from less than 0.1µm to 10+ µm.  More Info

  10. Surgical Loupes Defining Differences
    May 01, 2013
    Surgical Loupes help to alleviate eye strain by enlarging the image when you are working on tiny subjects or conducting precision operations. They are portable and easier to use than a surgical microscope. However, they are not created equal, and choosing the pair that's right for you is important to your satisfaction. See Selection Factors Involved in Choosing Loupes Choosing the correct surgical loupes for your application involves several factors, including resolution, working distance, field of view, depth of field,  magnific
