The Peri-Star Pro is a popular peristaltic pump. Here we see how to calibrate the pump so that the display shows the dispensed volume accurately.

In addition to the traditional RPM control, Peri-Star Pro also allows control of pump output by setting a calibrated flow rate. Flow rate is affected by tubing ID, tubing material, and rotor speed. Peri-Star Pro stores the flow rate relation of silicone tubing and rotor speed so that you can easily switch between controls for flow rate or RPM (revolutions per minute). Calibration is required for high precision pumping or after changing to a different type of tubing.

The PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. Here we will see how to load a piece of glass into the carriage.

The PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. Here are the resolutions for some common issues with the puller.

The PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. We will show you how to run a glass softening test.

The Peri-Star Pro is a popular peristaltic pump. Here we will show you how to install the tubing in the pump head so that you can use the pump.

The Peri-Star Pro is a popular peristaltic pump. Here we will show how to set the system parameters for your application.

Let’s look at the PUL-1000, a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. Here we will examine the design of the unit.

Vernier scales can be used on microscopes, stereotaxic frames and micromanipulators. The vernier scale was invented by French mathematician Pierre Vernier in 1631 as an upgrade on Pedro Nunes' measurement system for precision astrolobes. With a main scale and a sliding secondary scale, a vernier is used for making precise measurements. 

When using the Peri-Star Pro, solutions pumped should never come into contact with the pump. Here we will give you some guidelines for operating your peristaltic pump in a way that is safe for both the laboratory personnel and for the machinery.

A peristaltic pump is a popular appliance in any laboratory. Here you will find some tips for choosing the correct tubing to use for your application with your Peri-Star Pro peristaltic pump.

A peristaltic pump is a type of positive displacement pump used for pumping a variety of fluids, particularly clean, sterile or aggressive fluids. Here are five reasons to choose the Peri-Star Pro peristaltic pump.

WPI’s disposable scalpels come in eight different styles and can be used for a wide variety of applications. Here you can see what makes WPI inexpensive, disposable scalpels such a popular tool.

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.
