How to Cleave Surgical Fibers November 22 2016

How to Cleave Laser Surgical Fibers Purpose:        Provide simple instructions for reprocessing flat tip bare fibers for laser surgery. Summary:    Clean cut and flat optical faces are necessary for surgical efficacy in laser surgery. Badly cut fibers deliver energy to target tissue less efficiently and degrade more quickly than properly cut fibers. Step-by-step instructions…. Rationale:      A.A. Griffith developed the first theoretical model for fractures during WWI, inaugurating the Science of...

Instructions: IQ’s Sapphire™ Wafers for Cutting GC Capillary Columns September 30 2016

Cutting capillary and making gas-tight seals is critical to good GC practice and making seals on silica press-fit connectors requires almost perfect cuts (unless you are using Pres2fit™ connectors). Cleanly cut ends are also important for CE for minimizing distortions of the electric field at the column ends.  Capillary: The first thing that the separation scientist needs to understand is that not all silica capillary is the same. There are...

Smooth Passage™ Holmium Fiber Tips on ProFlex™ LLF August 29 2016

In the course of studying other manufacturers' holmium laser fibers we sometimes observe surprising differences. In this case, we knew that our tips were different -- heck, we gave them a special name -- but  just how much difference they made was the surprise.      The two fibers in the photo are "1000 micron", meaning they have either a 910 μm or 940 μm core inside a 1 mm diameter glass cladding. The upper...

A Practical Guide to Producing Safe & Efficient Surgical Fiber Working Tips March 31 2016

Tip failure occurs more rapidly where the tip begins with flaws, particularly where the optical output of the fiber is distorted. Most instructions for reproducing fiber tips are crude and non-scientific; “stripping and cleaving” instructions found on the internet, within other fiber manufacturers’ websites and IFUs typically yield highly variable and suboptimum results.   The following guide represents best practices in producing fiber working tips and is based upon the science of Fracture...
