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.
Scalpel blades come in a variety of shapes so that you can choose the ones best suited to your application.
The #10 blade is a commonly used blade for surgical applications. It is used for making large incisions through skin and subcutaneous tissues. It is similar to the #20 blade, which is somewhat larger. The #20 blade is used for larger incisions through thicker tissues or for dissection of the soft tissues in larger animals.
Blades #10, 15...more

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
