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 syringes are 10 µL and 100 µL syringes which can be installed on a UMP3 UltraMicroPump to give you repeatable injections in the nanoliter range. We will use the collar of the NanoFil syringe and the plunger as the two points to anchor the syringe to the pump.
- The syringe clamps are located at the end of the UMP3 pump head. Depress the clamp release button to open the syringe clamps.
- Position the cap of the plunger into the plunger cap holder at the rear end of the UltraMicroPump.
- Then slide the syringe collar into the into position next to the collar stop.
- Slide the syringe body into the syringe clamp so that the syringe collar fits snugly against...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 get even hotter as the puller is used continuously. To reduce the heat residue built-up, allow time for the colder ambient air to cool the components.
- The convection of air in the ambient environment (both inside...more

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.
These guillotines are designed for small animal researchers, and they come in three sizes. The guillotine is considered one of the most humane methods of dispatching laboratory animals. With a single downward motion of the handle, you can euthanize a rodent quickly and without trauma.
The blades are comprised of hardened steel, so they hold an edge and remain sharp, offering years of service. Sharp blades make the process swift for both the researcher and the subject. With proper care, the stainless steel blades resists corrosion, too.
A heavy-duty spring at the top of each guillotine securely holds the blade in an open position. This prevents the blade from accidentally falling and injuring laboratory...more
