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.
The PUL-1000 puller was designed with tight mechanical specifications and precision electronics for complete control of the pulling process and accurate reproducibility. It offers programmable sequences of up to four steps...more

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.
The PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. Here we will look at factors that affect the pulling of glass.
As the temperature of glass increases, the glass transitions gradually from a hard and relatively brittle solid state into a soft and viscous state. To form glass into certain shapes using a puller, heat is applied through a filament. Many factors affect the heat transferred from a filament to a glass capillary.
- The filament holders heat up when current passes through the filament, which can...more

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.
Your micro manipulator is a precision instrument, and it has been calibrated at the factory and is ready to use. As with any delicate mechanical device, your care and attention ensure long-term accurate performance. The following are some helpful hints that make this possible.
- When handling a micromanipulator like the M3301 or the KITE, always set it down carefully. Dropping it even a short distance can damage the general alignment and the adjustment.
- When it's not in use, close all the slides. When the guides are exposed, dust can get in those tracks. When...more

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.
In this video, we use the popular M3301 Micromanipulator to demonstrate how to mount a standard electrode holder. This M3301 is mounted on an M-3 Tilt Base which allows you to position it the way you want. The Tilt Base is mounted on a 5-lb. Weighted Base (WPI #...more

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.
A micromanipulator axis may begin to move gradually under its own weight even if it's not being touched. This phenomenon is referred to as mechanical drift, and it occurs from normal use of the manipulator axes over time. Each coarse axis control of the micromanipulator has its own separate adjustment to counteract drift. Let's look at the popular M3301 Micromanipulator. The procedure...more

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.
When we mount a micromanipulator on an M-3 tilt base, the tilt base can be adjusted to position the micromanipulator right where you want it. We will use our popular M3301 micromanipulator to demonstrate.
- The first thing we need to do is remove the ring clamp from the bottom of the micromanipulator. There are two screws that we...more

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.
Let's talk about mechanical drift on a micromanipulator and how to correct it. In this demonstration, we will use the popular KITE. A manipulator axis may begin to move gradually under its own weight, even if it's not being touched. This is called mechanical drift, and it happens from normal use of the manipulator over time. Each course axis control on the micromanipulator has its own adjustments. This procedure is very similar to the one we used for adjusting an M3301 micromanipulator. It also...more

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.
Flexible Magnetic Stand
The M11 Flexible Magnetic Stand is ideal for probe holders and other lightweight objects. The flexible arm bends like a snake and locks into position with a flick of the control lever. Here we show you how easy it is to set it up.
Magnetic Stand with Adjustment Arm
The M9 Magnetic Stand has an adjustment arm. We'll show you how to easily position it...more
