Product Overview
The Roundfin RD-1601A and RD-1601B Microtome Blades are professional disposable microtome blades manufactured from X46cr13 stainless steel with a PTFE coating for long service life, superior edge retention, and faster acceptable sectioning. Available in two configurations: the RD-1601A Low Profile (80*8mm x 0.25mm thickness) for routine paraffin sectioning, and the RD-1601B High Profile (80*14mm x 0.325mm thickness) for dense or hard tissue requiring a stiffer blade. Both feature a 35° cutting angle with a proprietary edge process, 50 blades per box, and compatibility with most microtomes and cryostats from all major manufacturers.

FAQ
What is the difference between RD-1601A and RD-1601B?
RD-1601A is a low-profile blade (80*8mm x 0.25mm) for routine paraffin sectioning. RD-1601B is a high-profile blade (80*14mm x 0.325mm) providing greater rigidity for dense, fibrous, or calcified tissue specimens.
How many blades per box?
Both models are packaged with 50 blades per box in a convenient dispenser format.
What material are these blades made of?
X46cr13 stainless steel -- a high-carbon martensitic grade for excellent edge retention and corrosion resistance. Features a PTFE coating that reduces friction and extends blade life.
Are these compatible with my microtome?
Yes. Compatible with most rotary microtomes and cryostats from Leica, Thermo Scientific (Microm), Sakura, and other major brands. Ensure your blade holder matches the profile (low or high) of the blade you select.
