World Precision Instruments has Developed An Innovative Approach To Sub Microliter Injection for Laboratory Research

What was once a laborious process to fill micro syringes wtih samples for injection has now become faster and easier. WPI's new NanoFil micro syringe injection system has interchangable tips to aid in the process. Filling a syringe now takes just a fraction of the time it once took. After filling, exchange the tip and begin injections with needles as small as 36 gauge or 110 microns.

(PRWEB) August 19, 2005 -- Responding to the needs of researchers, WPI has developed a unique syringe that will change the way sub microliter injections are performed.

Traditional sub microliter injection required the use of oil as a displacement transfer. This makes the process messy and risks contamination of the injected sample. NanoFilís low volume, flexible tubing eliminates the need for oil. Injection is now simpler, and less messy, and there is no possibility of oil contamination in critical applications such as ophthalmology research, intrauterine mouse embryo injections, and brain injections.

On a conventional replacing the tip in middle of the experiment is not practical. With the NanoFil, different gauge tips can be exchanged on the syringe by a simple twist of the brass lock, gently pulling out the tip, and replacing with the desired new tip.

The replaceable needles used with the NanoFil are available with either blunt or beveled tips. The blunt tip is used for injection into soft tissue and when a uniform solution distribution is needed. The beveled style is used for applications that involve the penetration of tough tissue. All of WPIís beveled tips have a unique 25 degree tri-surface bevel that is optimized for microinjection.

The 36 gauge tip is the smallest tip that is commercially available. The tip is so small that it can be inserted into the opening of the 33 gauge needle tip.
