  7. Sterilization Trays: Stainless Steel or Plastic?
    May 11, 2021
    Stainless steel and polymers are two of the most popular material options for sterilization trays used in the pharmaceutical and medical industries. In terms of toughness, long shelf life and resistance to contaminant absorption, surgical stainless steel outperforms plastic trays, especially for medical usage. Stainless steel trays also have a lower total cost over time.
  8. Why the Stainless Steel Finish is Essential
    May 10, 2021
    by Carmen Raymond Stainless steel sterilization baskets require a proper finish to increase the basket's versatility. The correct finish of stainless steel enhances it chemical resistance, handling characteristics and other key operational features. Let's take a look at the two most common finishes for stainless steel. Passivation Passivation is a corrosion-prevention treatment of stainless steel. This chemical process involves removing free iron from the metal's surface with citric acid or nitric acid. The process of passivation creates a thick protective oxide coating on the stainless steel, which makes it resistant to corrosive chemicals. The process of passivation cleans the stainless steel surface, removing all grease, oils and dirt. This results in a uniform, smooth appearance and finish. A smooth passivation finish minimizes the chance of rust damage of your sterilization basket, surgical instrument or stainless steel product. It also eliminates extra maintenance steps to protect your investments. Electropolishing Electropolishing is a method of dissolving the surface layer of a substance using a temperature-controlled electrolyte bath and an electric current. Stainless steel has a smooth, featureless surface after it is electropolished. The process of electropolishing removes all the microscopic debris and defects that would usually adhere to the surface of the steel, and it leaves the material with a smooth, non-stick finish. Electropolishing improves "weldability" without compromising the surface's hardness or causing peeling or abrading. It also creates a smooth surface that prevents pollutants from hiding in microscopic pits. By removing sharp edges and burrs created by welds or other metal forming processes, electropolishing makes equipment safer for manual use. In any application, an electropolished finish reduces minor injuries, as well as the risk of infection from open cuts.   When choosing sterilization baskets, consider the benefits of a proper finish. Both passivation and electropolishing make your surgical instrument baskets safer and easier to use and ensure a longer life of the product.   See Sterilization Baskets & Trays    
  9. How to Pull Glass using the PUL-1000 Micropipette Puller
    April 27, 2021
    The PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. Here is how to run a program that will pull two identical microelectrodes.   Loading a Program   We will use the keypad to navigate through the display. Use the arrows to navigate to LOAD (00). The top and bottom arrows on the keypad navigate numbers in increments of 1. The left and right arrows on the keypad navigate numbers in increments of 10. Press ENTER. The number will start blinking. Use the arrows to navigate to the program number you would like load. Once you reach the desired program, press ENTER to run the program and pull your glass.   Creating a New Program   Use the arrows to navigate to STEP 1 - HEAT. Press ENTER. The number will start blinking. Use the arrows to set the desired value for the heat. Press ENTER. Navigate to STEP 1 – FORCE. Press ENTER. The number will start blinking. Use the arrows to set the desired value of force. Press ENTER. Navigate to STEP 1 – DISTANCE. Press ENTER. The number will start blinking. Use the arrows to set the desired value for the pulling distance. Press ENTER. If you are only using 1 stage, you do not need a delay. If you need more than one stage, set your delay and repeat the above for stage 2. Once you have successfully set all numbers of your desired settings, navigate to the SAVE (00). Press ENTER. The number will start blinking. Use the arrows to navigate to the program number where you want to save your new program. Once you reach the desired display press ENTER.   Modifying an Existing Protocol
  10. Getting Started with your PUL-1000 Micropipette Puller
    April 23, 2021
    The PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. Here is a quick overview to get you started quickly.     Quick Start Setup Plug the power cord into the wall outlet. An LED light on the power supply illuminated when the unit is connected to power. Plug the power cord into the rear panel of the PUL-1000. Then, the power switch on the side panel illuminates. Press the Power button to turn on the display. To open the glass capillary clamps, place your thumb under the clamp and depress the release button with your index finger. This allows the carriages to move freely. Push the carriages together toward the center. Install the silicone glass capillary
  11. How to Calibrate the Peri-Star Pro Peristaltic Pump
    April 23, 2021
    The Peri-Star Pro is a popular peristaltic pump. Here we see how to calibrate the pump so that the display shows the dispensed volume accurately. In addition to the traditional RPM control, Peri-Star Pro also allows control of pump output by setting a calibrated flow rate. Flow rate is affected by tubing ID, tubing material, and rotor speed. Peri-Star Pro stores the flow rate relation of silicone tubing and rotor speed so that you can easily switch between controls for flow rate or RPM (revolutions per minute). Calibration is required for high precision pumping or after changing to a different type of tubing. One of the important and unique features of Peri-Star Pro is that the control of liquid flow can be expressed either as the rotation rate of the pump head (rotation per minute, or RPM) or directly as the flow rate in milliliters per minute (mL/min.) or milliliter per hour (mL/hr). This feature makes reporting and repeating the experiment much easier. In the flow rate mode, you only need to input the tubing inner diameter (ID) for the pump to calculate the flow. The accuracy of the flow rate will depend on the accuracy of the tubing ID. For applications requiring a high precision pumping rate, the pump can be easily calibrated with the tubing used. After calibration, an accuracy of 0.5% can be achieved. Watch the video to see how to calibrate your system.     Access the Calibration Menu Press the Control Knob to enter the setup mode in the main menu, then rotate the Control Knob to toggle between the four functions. Click the Control Knob to activate a selected function, and the LCD display shows the corresponding menu. Calibration is the first function of the main menu. This function calibrates the flow rate of the current tubing. The Calibration menu is only available when the pump is in Flow mode. In Rate Per Minute
