alloy

Surgical instruments are designed to perform diagnostic, therapeutic, or investigative operations having specific functions such as to cut or incise, retract, grasp, hold or occlude, dilate or probe, suture or ligate. 

The majority of surgical instruments are made of stainless steel or titanium (used where non-magnetic instruments are required). Stainless steel is an alloy that contains a minimum 12% chromium for corrosion resistance. Here's a quick comparison chart looking a various metals used in surgical instruments and the best applications for each.

Stainless Steel

Austenitic 316 steel, also called surgical steel or marine grade steel is the most common alloy used for WPI's standard line of instruments. Surgical steel has excellent corrosion-resistance, which makes it a good choice for biomedical implants or body piercing jewelery, as well as surgical instruments. It is in compliance with ASTM F138. Stainless steel (Inox) also has good salt resistance and temperature resistant up...more

Inox, Titanium, Dumoxel®, Dumastar®, Antimagnetic... Have you ever looked at the variety of metal alloys for surgical instruments and laboratory tools and wondered which is best for your needs? Here's a brief rundown.

Stainless Steel (Inox)

Why Stainless Steel is the Standard Alloy for Surgical Instruments

Our standard line of instruments is manufactured of highest quality materials. They are made of austenitic 316 steel commonly known as “surgical steel” or “marine grade steel.” Stainless steel, also known as Inox (from the French word "inoxydable"), is highly corrosion resistant and it is a common choice of material for biomedical implants or body piercing jewelry. It is in compliance with ASTM F138. This WPI line is an excellent alternative to German surgical...more

The manual microsyringe pump is a convenient tool for precise manual injection of fluid using glass pipettes or similar injection devices. The design allows visual feedback of flow at the pipette tip. They can also be used as a manual micro syringe pump for perfusion or withdrawal of liquids. The resolution of the injection volume can be continuously varied from 10 nanoliters to the microliter range, depending on the syringe used. Here we show you how to setup your system.

1. Loosen the set screw on the  Adjustable Micrometer Mount, but do not remove it.
2. Tighten the thumb screw on the Ajdustable Micrometer Mount.
3. Insert the digital micrometer or the manual micrometer through the hole on the Adjustable Micrometer Mount. Then, tighen the set screw.
4. Loosen the set screw on the Syringe Piston Mount Bracket.
5. Install the Bracket on the Spindle of the Micrometer. Tighten the set screw on the Bracket
6.  Loosen the Syringe Piston Mount Bracket thumb screw and the Syringe Mount Bracket thumb...more
