Whether you are working with your surgical instruments under bright lights or using a microscope, non-reflective black surgical instruments offer a distinct advantage. The titanium coating not only hardens and protects the cutting edge, but it also minimizes reflection from the surface of your instruments while you are working. They are corrosion resistant and biocompatible.

The new WPI MICRO-ePORE™ pinpoint cell penetrator is a simple and versatile system that can be used to facilitate microinjection of a diverse array of compounds and biomolecules into oocytes and pre-implantation stage mammalian embryos. Patent pending Flutter Electrode Technology assists in small, clean, precise membrane penetration without tearing or damaging the membrane. It results in substantially increased viability of embryos. In this quick video, Dr. Pelczar from the Center for Transgenic Models in Switzerland demonstrates the ease of cell penetration using the new MICRO-ePORE™.

For intracellular dual or differential studies, WPI's Duo773 has separate negative capacity controls and built-in active filtering that allows the precise balancing of time constants for artifact-free differential measurement. It comes complete with two probe headstages, 1015Ω and 1011Ω probes to monitor signals from ion-specific micro-electrodes as well as KCl-filled electrodes. Jim shows you how to safely unpack and properly setup your new Duo773.

EndOhm Chambers Re-engineered
EndOhm chambers are designed for making accurate TEER measurement of epithelial and endothelial cell cultures. The design keeps the top and bottom electrodes at a fixed gap and maintains the sample (cell culture insert) in a centered position inside. This design minimizes the variability associated with electrode positioning and gap, making EndOhm chambers more accurate and capable of generating reproducible results. WPI made some recent upgrades to the EndOhm chambers. - The NEW EndOhm Chamber is made of GLASS, making it easier to clean and more...more

Here are some frequently asked questions (FAQ) about Metal Microelectrodes.
...moreWhat metal type is best for my application?
W- Tungsten
Tungsten is a versatile and widely-used microelectrode material that offers a good balance between performance and cost.
ADVANTAGES
DISADVANTAGES
- Extremely strong and stiff metal provides probes with exceptional rigidity.
- Great for acute and chronic recording due to biocompatibility and lower cost.
- High corrosion resistance offers consistent long-term performance.
- Does not provide the same degree of electrochemical performance or stability as platinum-iridium alloy, making it a poor alternative for microstimulation.
- Lower charge transfer capacity of tungsten will result in larger, potentially

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 matter to surfaces.
