When you have exact specifications for your fiber optic assemblies, WPI delivers with proprietary qualified optical fibers designed by in-house optical engineers. You can count on superior performance from WPI's spectroscopy products and the published research scientists who design them. When you depend on reliable data for your discoveries, consider WPI's German Optics Department for qualified optical fiber and assemblies.

Here we discuss the process for submitting a request for an optical fiber to match your needs using the WPI optical fiber selection guide. There are five steps.

The UltraMicroPump3 is a versatile microinjection syringe pump designed to support the needs of a busy lab. The UMP3 Microinjector is suitable for delivery of media from nanoliters to milliliters. the UMP3 injecotor’s user interface and system design enables delivery of highly accurate and repeatable injections. The choice for thousands of scientists, it is widely cited in research papers.

Intuitive Touchscreen Display for Easy Setup

The SMARTouch controller has an intuitive touch screen interface and an easy-to-use menu for quick configuration of the syringe size, volumes and flow rates. The total system calibration is designed to eliminate human errors and reduce experimental processing time. Configuration can be saved and subsequently imported as a script via the USB port.

Control 2 Injectors Simultaneously

The SMARTouch controller can independently control two microinjection syringe pumps (microinjectors) simultaneously, providing complete freedom in the experimental procedures...more

Do you need a precision microinjector with an integrated pressure source for injections in the picoliter range? WPI’s new MICRO-ePUMP, which is comparable to the Ependorf Femtojet, is a portable solution for injecting DNA, RNA and proteins, as well as pre- and post- implantation in embryos. Whether you are doing disease modeling with zebrafish or viral research for SARS-CoV2, the MICRO-ePUMP has much to offer. Here are eight good reasons to choose the MICRO-ePUMP for your applications.

1. Convenient internal pressure source
   The convenient internal pressure source is designed to simplify intracellular injection. With the carefully regulated internal pressure source, there is no need of an external air supply.
2. Intuitive User Interface
   The touchscreen with simplified user interface and one button controller makes it easy for you to change parameters according to the microinjection application. You can navigate through the options and parameters easily with touch screen and single control...more

Researchers around the globe trust WPI products. Here are a few who have shared glimpses into their research areas.

WPI EndOhm chambers are used with WPI's EVOM2 meter for making TEER (transepithelial electrical resistance) measurements. After heavy use your background resistance measurement may start to rise. Your electrodes may need to be resurfaced to remove buildup of proteins, sugars and biological materials. Here Subhra demonstrates how to clean and resurface your EndOhm chambers.

This 900A video series of 6 videos is designed to help familiarize you with the basic operation of the 900A Micropressure System. The 900A was designed for measuring pressures in kidney tubules, and it has many applications. It has recently been used for measuring ventricular blood pressure in larval fish. We suggest that you become familiar with the information in the instruction manual and the parts and techniques you need to operate the system effectively. Please read the manual and watch these videos prior to setting up and testing your 900A Micropressure System. 

Instrument Description

• The 900A Micropressure System is designed to measure pressures from –200 to +400 mmHg in small blood vessels, cells and other electrolyte-filled micro-cavities.
• The main components are the 900A include the Control Unit, the Pressure Pod and a Probe that connects to a glass microelectrode. 
• The 900A utilizes an ion gradient at the tip of the microelectrode to set a null value of resistance in a...more

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.
