Frequently Asked Questions
How do Erma Patho Cutters compare to Feather blades?
Erma Patho Cutters are a cost-effective alternative to premium Feather blades, delivering reliable sectioning quality for routine histology applications. While Feather blades feature proprietary ultra-precision edge technology for demanding applications, Erma blades provide consistent performance for standard paraffin sections at 2-5 µm. Many laboratories use Erma for routine cases and reserve Feather for specialized protocols such as serial ultrathin sectioning.
Which Patho Cutter variant should I use for standard H&E sections?
The Patho Cutter R35 (Low-Profile) is the recommended variant for routine H&E paraffin sections at 2-5 µm thickness. It provides balanced sharpness and edge durability suitable for the wide variety of tissue types encountered in daily surgical pathology workloads, including breast, GI, skin, and prostate specimens.
Are Erma blades compatible with my microtome?
Erma Patho Cutters use the standard 80 x 8 mm low-profile format compatible with all major low-profile blade holders including Leica 818-type, Feather S35-type, Roundfin RD-1601A-type, and Thermo low-profile holders. If your microtome uses a standard dovetail mount blade holder for low-profile blades, Erma Patho Cutters are compatible.
How should I dispose of used Erma blades?
Used Erma microtome blades should be disposed of in a designated sharps container immediately after use. Never leave used blades on the microtome or workbench. Each dispenser box typically includes a used-blade slot for safe temporary storage. Follow your institution's biohazard waste disposal protocols for sharps contaminated with human tissue.
