The Accu-Cut® SRM™ 300 LT Manual Microtome is the first and only American made manual microtome with a patented multi-colored LED backlit chuck to illuminate paraffin embedded
Enlightening the block
Tissue sectioning on microtomes is now illuminated.
The Accu-Cut® SRM™ 300 LT Manual Microtome is the first and only American made manual microtome with a patented multi-colored LED backlit chuck to illuminate paraffin embedded tissue samples making them much easier to see and safer to section.
The microtome chuck backlight increases contrast between specimens and paraffin so users can see exactly where the tissue is located to prevent cutting through a small biopsy or previously sectioned block.
The SRM 300 LT features a 3D Precision Chuck for accurate alignment of the block face to the blade on all three axes (XYZ), which is crucial for recuts. The sturdy microtome chuck retains its position when locked and unlocked, eliminating any time and effort spent realigning the cutting angle. The 3D Precision Chuck can quickly and accurately be returned to a zero position with the dial indicators.
The compact and ergonomic design helps to minimize cumulative stress on the user and increases both efficiency and productivity. The course hand wheel is optimally sized and positioned for comfortable trimming in either clockwise or counterclockwise rotation and is switchable by the user.
The SRM 300 LT includes many exclusive features that reduce the risk of accidental injuries associated with blade exposure:
- The first and only Brake Lock Indicator that displays that the chuck is locked and will not move while the user interacts with the microtome, providing users with peace-of-mind.
- The Red Blade Guard can be set in the UP position to protect the user from accidental exposure to the blade edge while sectioning.
- A Universal Blade Holder base, featuring lateral displacement, allows operators to use the full length of the microtome blade without releasing the blade clamping mechanism or direct blade manipulation.
- The SRM 300 LT is the first and only microtome to offer a space-saving Tool Organizer giving back precious bench space.
Compatible with Accu-Edge® Disposable Blades, the Accu-Cut SRM 300 LT ensures superior microtome tissue sectioning in the precise art of cutting quality tissue samples section after section, time after time.

Microtomy troubleshooting
Thick and thin sections/How do I correct thick and thin sections?
Thick and thin: Part of the section is thick, and part of the section is thin, reflecting inconsistent staining.
more details
Knife marks/What causes knife marks in sections?
Knife marks: Vertical lines running through the entire section.
more details
Chatter, aka Venetian blinds/What causes microtome chatter?
Chatter, aka Venetian blinds: parallel lines in the tissue or separation of tissue into fine lines
more details
Moth holes/Why are there holes in tissue sections?
Moth holes: parallel lines in the tissue or separation of tissue into fine lines
more details
Micro chatter/What causes microscopic cracks in tissue sections?
