“A” OR “V” PATTERN
Throughout the series, the “V” pattern is the all-purpose clamp. commonly used on all veins,
and almost all arteries. The “A” pattern is designed for exceptionally thick-walled vessels and slippery arteries.
The slight incurve of the tips of the “A” pattern jaw provides extra security against slippage.
BLACK OR PLAIN FINISH
All clamps are now available in either a black or matte (dark gray) finish. The black finish
helps minimize eye fatigue, and also helps avoid burned-out highlights in photography and on-screen.
The matte finish features a dark gray, minimally reflective surface. The selection of a black
or matte finish clamp is a metter of preference.
CLAMP SIZE AND CLAMP PRESSURE
When choosing the right size of clamp for your work, clamp pressure is an important consideration.
Clamp pressure is determined by the closing force of the clamp (in grams), divided by the area of the vessel
wall that is compressed between the jaws (in square millimeters). Thus, the smaller the area, the higher the pressure is,
inversely proportional to the vessel size. Each size of clamp has its own different and carefully calibrated closing force.
Each Clamp size is designed for a specific range of vessel diameters.
