Product Overview
The Roundfin NE-410 is a precision ultrasonic tissue section atomizer designed for histology and pathology microtomy workflows. Using ultrasonic atomization technology, it generates a fine, adjustable mist that contacts paraffin sections during cutting — preventing tissue rolling, ensuring full section expansion, and eliminating skirt wrinkles. The result is consistently flat, high-quality tissue sections ready for mounting and staining.

Key Features
- Ultrasonic Atomization Technology — Generates a fine, adjustable mist with variable fog volume and airflow — optimized for different section thicknesses and paraffin environments.
- Rolling Prevention & Section Expansion — The ultrasonic mist contacts paraffin sections during cutting, preventing the tissue from rolling and ensuring complete, wrinkle-free expansion on the water bath.
- Bellows-Directed Mist Delivery — Fog travels through a flexible bellows tube for precise, directional application — making either direct or indirect contact with the wax block and section.
- Compact & Portable Design — Lightweight body sits directly on the microtome platform next to the blade holder, requiring no additional bench space or mounting hardware.
- Tool-Free Atomizer Replacement — Replaceable atomizer unit can be changed without tools in seconds. Easy to disassemble and clean between protocols to prevent cross-contamination.
- Universal Microtome Compatibility — The compact design and flexible bellows positioning make the NE-410 compatible with most standard rotary microtomes including Leica, Thermo Scientific, and Sakura models.
Applications
| Scenario | How the NE-410 Supports |
|---|---|
| Routine Histology Sectioning | Prevents section rolling on standard 3-5μm paraffin sections, reducing the need for manual section manipulation with forceps and minimizing tissue damage during mounting. |
| Difficult or Fibrous Tissue Types | Adjustable mist volume provides extra humidification for dense, fibrous, or brittle tissue specimens that are prone to rolling and fragmentation during sectioning. |
| High-Throughput Diagnostic Labs | Reduces section rejection rate from rolling and wrinkles, improving first-pass section quality and overall laboratory throughput — fewer re-cuts per block. |
| Training & Educational Settings | Helps students and trainees produce consistent, flat sections while learning microtomy technique — reducing frustration and improving training outcomes. |
Frequently Asked Questions
How does ultrasonic atomization improve section quality?
Ultrasonic vibration creates an ultra-fine water mist (vapor-sized droplets) that gently humidifies the paraffin block surface and the cutting zone. This micro-humidification reduces static electricity, softens the paraffin slightly at the cutting edge, and prevents the tissue section from curling or rolling as it leaves the blade — resulting in flatter, more intact sections ready for the water bath.
Is the NE-410 compatible with my microtome?
The NE-410 is designed with a compact body and flexible bellows positioning that makes it compatible with most standard rotary microtomes, including Leica (RM series), Thermo Scientific (Microm HM series), and Sakura models. The unit sits directly on the microtome platform near the blade holder — no mounting hardware or modifications required.
How often does the atomizer need to be replaced?
Under normal laboratory use with distilled or deionized water, the atomizer unit typically lasts several months before requiring replacement. Mineral buildup from tap water will shorten atomizer life — always use distilled water for optimal performance and longevity. Replacement atomizers are available from Roundfin and can be changed in seconds without tools.
Can the mist volume be adjusted for different tissue types?
Yes. The NE-410 features adjustable mist volume and airflow controls, allowing the operator to fine-tune humidification based on tissue type, section thickness, ambient laboratory humidity, and paraffin characteristics. Higher mist output for dense or fibrous tissues; lower output for thin routine sections.
