- Microinjection processes use either metal microinjection needles or glass micropipettes to inject small liquid volumes. For example, genetic material may be inserted into a living cell, a drug introduced into an eye or brain, or fluid injected into a muscle. Typically, microinjection is performed under a microscope. A stereotaxic frame setup may be required.
Recently, WPI introduced its customizable Microinjection System with everything you need to get started. We can help you customize your system with many options and microinjection system accessories. The basic system includes:
Microinjection pump like the PV820 Pneumatic PicoPump
LED lighted microscope base with a PZMIII Stereo Microscope and an articulating mirror
WPI offers a variety of pumps along with special syringes, stereotaxic frames, glass capillaries and needles. The setup you choose depends on the size of your microinjection aliquots, the volume to be injected and the size of needle or glass tip you choose. In addition, we offer an electroporator for transfection procedures.
Whether you are working with Danio rerio (zebrafish), Xenopus, Drosophila or Caenorhabditis elegans, we can help you customize a microinjection system for your application.

Our black instruments are coated with titanium nitride (TiN), an extremely hard ceramic material.The TiN coating hardens and protects the cutting edge. Ceramic coated anti-reflective instruments are perfect for microscopy and microsurgical applications.
Coating surgical instruments with a black ceramic offers several distinct advantages.
Wear and tear resistant
The coating adds a thin layer to the metal instrument that actually makes the instrument harder, offering surgeons greater precision and perfection. This anti-glare surface minimizes any reflection off the surface of your instruments. The incredibly smooth coating improving the instruments' resistance to corrosion and minimizing friction. The reduced wear and tear means coated instruments last considerably longer. The ceramic coating is virtually impenetrable, because the raw material is bonded to the instrument both physically and chemically. The black coated instruments are much more resilient to the pressure of daily use and chemical processing. Coated instruments last considerably longer.

September 12, 2019Researchers around the globe trust WPI products. Here are a few who have shared glimpses into their research areas. If you would like to share your story, please email us at firstname.lastname@example.org. Meet Xiling Li Xiling Li is a fifth year graduate student at the University of Southern California who is interested in neuroscience, especially signal transduction at a neuromuscular junction. Ideally, she wants to look at the properties and molecular mechanisms for synaptic transmission and plasticity and how these are modulated during development and in disease models. Xiling uses WPI's line of microinjection instruments and electrophysiology equipment.

September 06, 2019Benefits of black coated surgical instruments Black coated surgical instruments are not only visually more attractive than the stainless-steel ones, there are several other benefits as provided below: - Non reflective surface reduces eye-fatigue - Has prolonged life - Up to 10 times harder than stainless steel - 60% lower wear rate than stainless steel - Corrosion resistant due to oxidized aluminum coating - Anti-allergic due to the absence of Chromium and Nickel coating - Easy to clean Making of the black coating instruments The black coatings are created by applying a layer of Titanium Aluminum Nitrate (TiAIN) to the instrument, using an environmentally friendly Physical Vapor Deposition (PVD) process. In this process Titanium and Aluminum are magnetron-sputtered onto the substrate in a vacuum chamber. The metal particles of the ta
August 21, 2019Are you looking for a microliter or sub-microliter and high precision syringe that holds needles as small as 36 gauge (G), in addition to having the capability to connect to quartz tubing? WPI’s NanoFil is the answer. We offer NanoFil syringes with NanoFil needles or the option to connect the NanoFil syringe to quartz tubing to use in research studies, mainly involving sub-microliter volume injections into animal tissues. Why Select WPI’s NanoFil (Syringe and Needle) System? Low Dead Volume The dead volume of NanoFil's is minute or neglig
August 09, 2019Whether 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. See Selection
