Product Features

Antistatic Waste Tray (Brush Included)

With the Antistatic Waste Tray, BIOCUT helps you keep your workplace clean, efficient, and debris-free. The tray is made from antistatic material which prevents paraffin waste from sticking to the walls. It provides unmatched efficiency by reducing your cleaning time from minutes to seconds.

Antistatic Waste Tray (Brush Included)
High or Low-Profile Blades… it's your Choice

2-in-1 Blade Holder

With the 2-in-1 Blade Holder, you can easily switch between high and low-profile blades without changing blade holders. In addition, compared to our previous manual microtomes, the new modular design of blade holder helps you maintain individual components and efficiently service your equipment over time.

Put (Almost) Anything on Top of your Microtome!

Our new models feature 40% more surface area on top of the microtome (23.5cm W x 27.5cm L, vs. 21.7cm W x 21.2cm L on the RM22xx series) so you can store the tools you need for your job – brushes, blades, wipes, and more.

40% more Surface Area on Microtome Top Compared to older RM22xx Series

Precision-Orientation System

Always get back to a 0-position home on the microtome, regardless of how you (or another tech) have changed the instrument's orientation.

Force Balance System

Eliminates the risk of injury to the operator or specimen by an unbalanced object head.

Silent Retraction

If working in a quiet environment, BIOCUT helps you concentrate and is your ideal sectioning partner with little-to-no noise during retraction.

Frequently Asked Questions

HistoCore Microtomes

Does the new HistoCore RM antistatic tray fit on the older RM22xx series?

No – the microtome base plates of both series have different dimensions and are not compatible with each other.

How does the new antistatic waste tray reduce contamination?

The antistatic waste tray is made from resistant antistatic material to avoid debris sticking to the walls of the tray.

Is the new 2-in-1 blade holder compatible as a whole assembly with the older RM22xx series?

Yes – only in the combination blade holder and 2-in-1 blade holder.

Can we still use the backlighting with the new blade holder base for the 2-in-1 blade holder?

No – the 2-in-1 blade holder base does not have the cut-out for the backlighting.

Which accessories of the older RM22xx Series cannot be used with the HistoCore RMs anymore?

  1. Small section waste tray
  2. Large section waste tray
  3. Top tray – HistoCore RM top tray is 40% larger than the RM22xx series tray
  4. Cooling Device – too small to be placed on instrument top. However, it’s still good to place next to the instrument



What is the advantage of the personalized coarse feed wheel?

Convenience and ease-of-user – users can select their personal preference of coarse feed wheel turn direction. This feature is preserved from the RM22xx series, allowing users to trim at the high pace.

What is the advantage of “Fast homing”?

The return speed of the object head from front to home position has been reduced from 26 seconds (older series) to 13 seconds (new series). This accelerated speed helps to shorten the sectioning process each time the object head is returned to home position.

What is the advantage of the Memory Position?

When batch trimming and using the same height of blocks, Memory Position will help to accelerate the sectioning.

  1. First insert a new block
  2. Bring the block to the blade
  3. Set the Memo position (stored)
  4. Trim
  5. Remove block for re-cooling
  6. Press “Memo” – the object head returns to the set object change position
  7. Insert a new block – check position
  8. Trim again
