Key Features
- Advanced Coating Technology — Proprietary blade coating reduces cutting friction for smoother sections, minimizes compression artifacts, and extends usable edge life compared to uncoated blades.
- High-Profile Rigidity — Taller blade body provides superior stability when sectioning dense, calcified, and fibrous tissues that challenge standard low-profile blades.
- Two Performance Tiers — MX35 Premier for standard high-quality histology; MX35 Ultra with enhanced coating for maximum durability in high-throughput clinical laboratories processing 200+ blocks daily.
- Thermo Fisher Quality — Manufactured to Thermo Scientific's rigorous specifications with ISO-certified quality control and full batch traceability for clinical accreditation compliance.
- Universal High-Profile Compatibility — Fits all standard high-profile blade holders including Thermo MX35-type, Leica 819-type, Feather A35-type, and Roundfin RD-1601B-type holders.
- Optimized for Challenging Specimens — Delivers consistent ribbon sections from bone, cartilage, breast, uterus, prostate, and other dense or fibrous tissues that cause premature blade degradation.
FAQ
What is the difference between MX35 Premier and MX35 Ultra?
The MX35 Premier is the standard high-performance blade suitable for routine to demanding histology applications. The MX35 Ultra features an enhanced proprietary coating that provides approximately 20-30% longer edge life, making it the preferred choice for high-throughput clinical laboratories and laboratories processing predominantly dense or calcified specimens. Both variants share the same base steel and edge geometry.
Can MX35 blades be used on non-Thermo microtomes?
Yes. The MX35 uses the standard 80 x 8 mm high-profile format compatible with all major high-profile blade holders, including Leica 819-type, Feather A35-type, Sakura Accu-Edge HP, and Roundfin RD-1601B-type holders. No special adapter is required as long as your microtome uses a standard dovetail mount for high-profile blades.
How many blocks can one MX35 blade edge section?
With standard paraffin-embedded tissue at 3-5 µm thickness, each blade edge typically sections 80-200 blocks depending on tissue type. The MX35 Ultra's enhanced coating pushes this toward the upper end of the range and maintains section quality longer when processing difficult specimens. For bone or heavily calcified tissues, expect fewer sections and rotate the blade edge more frequently.
Are these authentic Thermo Scientific blades?
Yes. Roundfin supplies 100% original Thermo Scientific MX35 microtome blades manufactured by Thermo Fisher Scientific. We are an authorized distributor. Every box carries genuine Thermo Scientific packaging and lot numbers for full traceability. Certificates of authenticity and lot-specific quality documentation are available upon request.
