 Micromanipulators  are an important tool used to execute minute, fine-tuned movements critical for various applications including microinjection into cells or tissue, microscopy, as well as for research involving biological and nano-engineering implementation. Before selecting a micromanipulator, consider the following to choose the best option for your application:

Hemostatic forceps, also called ring forceps or hemostats, are common surgical instruments used in medical, veterinary, and laboratory settings to control bleeding during procedures. Hemostats are used to clamp blood vessels, tissues, or other small structures, effectively minimizing blood flow during surgical procedures. Hemostats prevent excessive bleeding for the subject and offer a clear view of the surgical site for the operator. Here’s a brief introduction to the features and uses of hemostatic forceps in a laboratory setting.

Cleaning laboratory syringes helps prevent contamination and ensures accurate dosing. You should always adhere to the protocols of your institution and the manufacturer of your syringe. Specific cleaning requirements may vary based on the intended use of the syringe, its material composition , and the sample fluid introduced. Here is a typical protocol for cleaning a laboratory syringe.

Laboratory syringes are used for accurate measurement and administration of fluids in medical, laboratory, and industrial settings. Proper maintenance is crucial to ensure their functionality and accuracy. Here we will examine some common maintenance issues you may encounter with your reusable laboratory syringes.

The foundation of many research laboratories is the ability to do in vitro studies, which rely on the ability to culture cells in the laboratory. Cell culture technologies have advanced significantly, allowing researchers to successfully culture many types of cell lines.

Laboratory forceps are surgical instruments that come in a variety of types. Here’s a brief overview to help you choose a set of forceps for your application. Surgical forceps can be divided into two broad categories, thumb forceps (also called tweezers) and hemostatic forceps. Tweezers can be further divided into dressing forceps and tissue forceps.

The EVOM™ family of TEER measurement meters have been cited in over 16,000 peer-reviewed, scientific journal articles. The EVOM™ Manual has been designed to improve workflow efficiency, increase stability, and provide more repeatable measurements than older Trans Epithelial Electrical Resistance (TEER) meters including the Millipore MilliCell® ERS-2, Millipore MilliCell ERS and World Precision Instruments EVOM2, EVOM and EVOMX. Here’s a quick summary of benefits of the EVOM™ Manual versus the MilliCell ERS voltohmmeter.

The EVOM™ Manual requires an electrode for use. Choose an electrode suitable for your application. Here's a matrix to help you choose an appropriate EVOM electrode.

WPI was recently featured in Aviation Week as a supplier of stainless steel mesh baskets for manufacturing and electronics.

Choosing the right syringe type depends on the specific application and the requirements of your task. Syringes come in various sizes, materials, and designs, each suited for different purposes. Here are some factors to consider when selecting a syringe type.

Deciding which syringe pump is best for your application involves factors like the flow rate, number of channels, and precision that you require to select and appropriate system. Use a syringe pump when manual syringe handling will negatively impact the delivery of your sample, and to precisely regulate the rate of fluid dispensed from a syringe. These pumps are utilized in diverse areas, including biomedical or chemical applications, general research, healthcare, and in industrial settings. Below is a guide to assist in deciding which syringe pump is most suitable for you:

On December 29, 2022, the FDA Modernization Act 2.0 was signed into law, which allows alternatives to animal testing for new drug development. This has opened the door for new pathways to drug discovery and development that involve Artificial Intelligence, cell culture-based assays, and organ-on-chip applications. It also moved the field closer to the three Rs of animal testing:

WPI’s FluoroDish™ cell culture dishes are optimally designed for a wide variety of cell culture and embryology experiments including high resolution imaging, live cell imaging, electrophysiological recordings of fluorescently tagged cells, and microinjection.  FluoroDish™ cell culture dishes are far better than standard petri dishes, because they are designed with optical quality glass bottoms, which offer superior imaging using the latest microscopy technology. WPI’s FluoroDishes™ have been cited in over 550 peer-reviewed publications by cell culture laboratories across the world.

Building a custom surgical instrument kit gives you the flexibility, precision, and control you need to advance medical knowledge, improve patient outcomes, and push the boundaries of surgical science.

Surgical forceps have been used in various forms from ancient times and have evolved into a indispensable instrument for modern surgeries. Forceps are surgical instruments for the practice of medicine which are used for grasping, holding, and manipulating tissues and objects during surgical procedures.

Syringes have a wide range of applications in a laboratory setting due to their ability to accurately measure and dispense liquids. Common lab uses include transferring precise volumes of liquid samples from one container to another for dilution, mixing, reagent preparation, and sample extraction. You may be using them for analytical techniques, like chromatography (such as high-performance liquid chromatography (HPLC) or gas chromatography), spectrophotometry, and titration. Syringes are often used for precise dosing and delivery of reagents during chemical reactions and synthesis processes, or in life science research for aspirating media, adding growth factors or nutrients, and transferring cells. In medical and veterinary research, syringes are used for the injection or infusion of drugs, vaccines, or contrast agents into animal models or cell cultures. Researchers can use lab syringes to collect liquid samples, particularly in environmental monitoring, water quality analysis, or biological sample collection. In microfluidic applications and lab-on-a-chip systems, syringes are perfect for precision control of fluid volumes and flow rates.

WPI’s EVOM™ Technology is a well-established, non-invasive method to verify tissue integrity or barrier function, confluence, and tissue properties in 2-D and 3-D formats. To get the best TEER measurement results with WPI’s EVOM technology, you need to select suitable electrodes based on your application. 

Here are some criteria to consider when selecting a TEER measurement electrode.

In 2022, the United States Food and Drug Administration (FDA) approved 37 new drugs, of which 20 were chemical entities and 17 were biologics. In 2023, drug discovery remains strong with many new advancements a result of changing landscapes in both the types of drugs that are being developed and the new and innovative assay that are being launched to evaluate drugs preclinically. Therapeutic development is still highly focused on diseases that affect large populations of people for which there are lack of effective treatments, with 2023’s most anticipated drug launches expected to be in areas of cancer, Alzheimer’s disease, cardiovascular disease, and ulcerative colitis.
