  1. How to Clean Surgical Instruments Using an Ultrasonic Cleaner
    March 13, 2019
    Prior to sterilizing surgical instruments, it is a good idea to make sure you have cleaned them to remove blood, tissue and all other organic material.  If soiled materials dries or is baked onto the instruments, it will interfere with microbial inaction and can compromise the sterilization process. Cleaning is the removal of foreign material (e.g., soil and organic material) from objects and is normally accomplished using water with detergents or enzymatic products. The most common type of mechanical automatic cleaner is the ultrasonic cleaner. Ultrasonic cleaners are used in conjunction with detergents and enzymatic cleaners.  Ultrasonic cleaning removes particulates by cavitation (bubbles) and implosion. Waves of acoustic energy are transmitted in aqueous solutions and disrupt the bonds that hold particulate m
  2. Get a Clean Consistent Cut Every Time with Biopsy Punches
    August 22, 2018
    Clean, Consistent Cut Every Time When you need to quickly take minimally invasive, small samples, the biopsy punch is an easy choice. The biopsy punch is a hand held, pencil-shaped instrument with a slender, pencil-like body. It is lightweight with a hollow, circular, stainless steel, cutting tip. In 1887 Edward Lawrence Keyes, the first president of the American Association of Genitourinary Surgeons, was the first doctor who documented the importance of using the biopsy punch for dermatological diagnostics. He observed that the skin tissue samples can be obtained without complications, minimal bleeding and no need for suturing. Uses for Biopsy Punches Punches are not solely used in dermatology. Biopsy punches are also designed for therapeutics,
  3. How Do I Select Appropriate Surgical Instruments for My Application?
    March 13, 2018
    When you are selecting surgical instruments for a procedure, here are a few key points to consider What procedure are you performing? Published research papers usually indicate which instruments other researchers have used for similar procedures. The correct surgical instrument for a particular procedure makes a difference on the outcome of that technique. What is the size of your subject? An instrument that is perfect for a 200­–300 g rat (about 22–25 cm long) may not be the best choice for a neo-natal mouse of about 15 g (about 1–2.5 cm long). How often will the instrument be used? If you perform more than 100 cuts per day, a pair of titanium scissors or a pair of scissors with tungsten carbide inserts would be worth considering. They stay sharp longer.
  4. Surgical Instrument Care and Handling
    June 19, 2015
    The proper care and handling of your valuable surgical instruments will improve their longevity and function. Choose a protocol appropriate for your environment from the cleaning techniques below. See the videos here. RINSING Immediately after use, rinse instruments under warm or cool running water to remove all blood, body fluids and tissue. Dried soils may damage the instrument surface and make cleaning very difficult. Do not use hot water as this will coagulate proteinous substances. CLEANING TECHNIQUES Time, temperature, and agitation play important roles in the cleaning process. Time — the efficiency of cleaning chemicals is often time dependant Temperature — higher temperature cleaning solutions result in better cleaning Agitation — whether manual or ultrasonic, it is helpful in loo

  7. New Product: Pickup Tweezers
    September 03, 2013
    WPI now offers suction tweezers that are ideal for picking up small objects with a flat surface. The Pickup Tweezers are perfect for handling and positioning coverslips, removing small tissues from a solution or manipulation of small electronic components. The Pickup Tweezers (#504523) require no power or batteries, and are safe from all electrostatic discharge. This kit includes the metal body (handle), a straight metal needle, an angled metal needle, three rubber cups (4, 6 and 9mm diameter) and a lubricant set. When your fingers are just too big, and standard tweezers are awkward, the Pickup Tweezers are perfect.
  8. Which Alloy is Best for My Surgical Instruments?
    April 30, 2013
    Inox, Titanium, Dumoxel®, Dumastar®, Antimagnetic... Have you ever looked at the variety of metal alloys for surgical instruments and laboratory tools and wondered which is best for your needs? Here's a brief rundown. Stainless Steel (Inox) - Our standard line of instruments are manufactured of highest quality materials, they are made of austenitic 316 steel commonly known as “surgical steel” or “marine grade steel.” Stainless steel, also known as Inox (from the French word "inoxydable"), is highly corrosion resistant and it is a common choice of material for biomedical implants or body piercing jewelery. It is in compliance with ASTM F138. This WPI line is an excellent alternative to German surgical instruments. The high-quality, corrosion-resistant instruments are available at a fraction

  10. DLC Coating Multiplies Useable Life of Surgical Instruments
    April 29, 2013
    When applied to surgical instruments, Diamond-Like Carbon coating dramatically increases the life of the instrument. Because DLC-coated surgical instruments are incredibly durable and resistant to wear from chemicals, moisture and atmospheric conditions, they have a much greater useful lifespan. According to the manufacturer, pure DLC coatings as thin a 2-3μm can increase the lifespan of a pair of Vannas scissors more than 100 times that of its uncoated counterpart. DLC is a revolutionary new coating that is being tested in a variety of industries. For example, when engine parts are coated, the DLC reduces friction and corrosion, increasing the life of the engine. In a completely different industry, DLC coating is being tested on metal heart valves. The coating is non-toxic, and it is so slick that biological
