WPI’s disposable scalpels come in many styles and are ideal for students, researchers, and crafters. Here we will describe some of the uses for these popular blades.

NanoFil™ is a unique low volume gas tight syringe developed for improved microinjection in mice and other small animals. Here we show you several ways in which the NanoFil can be used for making injections. You can install the syringe on WPI’s UMP3 UltraMicroPump, using SilFlex tubing and a holder, so you can accurately inject by hand. You can install it in a stereotaxic frame. You can also directly inject by hand.

NanoFil™ is a unique low volume syringe developed for improved microinjection in mice and other small animals. Here we'll show you how to install your needle in a way that prevents damage to the gasket and keeps your needles straight.

NanoFil™ is a unique low volume syringe developed for improved microinjection in mice and other small animals. Using a UMP3 UltraMicroPump combined with the syringe allows you to make repeatable injections in the nanoliter range. Here we'll show you how to install a NanoFil Syringe on the UMP3 UltraMicroPump.

NanoFil™ is a unique low volume syringe developed for improved microinjection in mice and other small animals. During our field trials, the 35-gauge needle was scientists’ most popular and preferred NanoFil tip. The combination of its strength, length, durability and clogging resistance creates a solid balance.

NanoFil™ is a unique low volume gas tight syringe developed for improved microinjection in mice and other small animals. RPE and IO kits are specially designed for “hands-free” and oil-free Gas Tight Injection System. Originally developed for retinal pigment epithelium and intraocular injection, they can also be used for other applications.

PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes used in intracellular recording, patch clamp, microperfusion and microinjection. The PUL-1000 is capable of producing a vast array of pipette shapes, such as a long graduated taper, a short graduated taper and a short taper bee stingers. Here's a quick introduction the PUL-1000 research puller.

NanoFil™ is a unique low volume syringe developed for improved microinjection in mice and other small animals. NanoFil needles are specially designed with a small outside diameter and spear point for shallow penetration and to cause the least amount of tissue damage. 

NanoFil™ is a unique low volume syringe developed for improved microinjection in mice and other small animals. It comes in both 10 and 100 microliter volumes and can be paired with a UMP3 UltraMicroPump for making accurate microliter injections. NanoFil stainless steel needles range in size from 33 to 36 gauge.

DCAP guillotines are designed for small animal researchers, and they come in three sizes. The DCAP is considered one of the most humane methods of dispatching laboratory animals. With a single downward motion of the handle, you can euthanize a laboratory rodent quickly and without trauma.

The M3301 is a popular micromanipulator used for laboratory research. Here we will show you how to mount a microelectrode holder on the M3301 Micromanipulator. The procedure is very similar for most manual micromanipulators.

Pulling micropipettes or microelectrodes is a science and an art, requiring some finesse. Here we discuss the five major factors which can affect the shape of a pulled glass micropipette or microelectrode.

Manual micromanipulators are common equipment in a laboratory, and with proper care and handling they should last many years. Here's a few tips on how to take care of your new manipulator.

Over time, you may experience mechanical drift in one or more of the axes of your manual micromanipulator. Here we show you how to adjust for that. The process is similar for other styles of manual micromanipulators. We will look at the process for adjusting all three axes of a KITE micromanipulator.

M3301 is a popular manual micromanipulator at WPI. These manipulators are typically mounted on a stand or table to ensure stability. In this video we show you how to mount the manipulator on an Tilt Base (WPI# M-3) with a WPI# 5464 5 lb. weighted base.

The process is similar for other styles of manual micromanipulators. We will look at the process for adjusting all three axes of a KITE micromanipulator.

Magnetic stands act as an invaluable extra hand around the laboratory to hold an electrode, digital dials or tools. The base houses a strong magnet which can be activated by turning the switch. Position the magnetic stand on a weighted steel base plate or metal desk and rotate the dial counter-clockwise to engage the magnet. We offer multiple styles of magnetic stands, but these videos show a couple options.

WPI pre-pulled pipettes (MicroTips) are a popular choice for pharmaceutical companies carrying out CCIT (Closed Container Integrity Testing). Each MicroTip is individually tested and inspected and can be shipped with a certificate of compliance.

World Precision Instruments (WPI) offers a broad range of research instruments for zebrafish (Danio Rerio) research, from the time the genetics of the subject are modified through the point where the physiological effects of the change are monitored. Whether researchers are performing microinjection or making cardiovascular measurements, the WPI product line includes instruments for research on oocytes, embryos, larvae and adult zebrafish.

The PV850 Injector is designed to simplify intracellular injection and a variety of other microinjection tasks. The PV850 uses regulated air pressure for injecting cells with fluid. Injected volumes range from picoliters to nanoliters. The port supplies positive pressure for high-pressure ejection maximum of 87 PSI.

The PV850 uses regulated air pressure for injecting cells with fluid. Injected volumes range from picoliters to nanoliters. The port supplies positive pressure for high-pressure ejection maximum of 8 7PSI.

Designed to simplify intracellular injection and a variety of other micro­in­jec­tion tasks, WPI’s PicoPumps (PV830 and PV820) use precisely regulated pres­sures for se­cur­ing cells and injecting them with fluid. Injected volumes range from picoliters to nanoliters. Separate ports supply positive and negative pressure—pos­i­tive pressure for high-pressure ejection, and suction for supporting the cell or for filling the pipette from the tip. In this quick series, you can see how to setup a PicoPump.

It is not difficult to retrieve the syringe post that has slipped inside the SP or SPLG syringe pump.
