The Combination Tissue Flotation Bath and Slide Dryer is a high-efficiency histological workstation that integrates a flotation bath, dryer, and oven into a single, digitally controlled unit. It offers high throughput (up to 180 slides per oven cycle) and precise thermal control. It is an ideal solution for pathology laboratories looking to optimize space and guarantee maximum quality in the adhesion of paraffin tissue sections to slides.

This Integrated Flotation Bath & Dryer is a streamlined workstation designed to consolidate the critical paraffin section mounting process into a single, unified instrument. It seamlessly transitions tissue ribbons from a heated water bath for gentle expansion, to a warm drying surface for adhesion, and finally into a dedicated oven for accelerated curing. By integrating these three key steps, this system standardizes workflow, saves valuable bench space, and enhances preparation efficiency for high-quality histological slides.
The CS-RD-2018 is used in conjunction with the following equipment and materials in the histopathology laboratory:
Standard glass slides for mounting the sections.
Used to transport and hold slides within the Oven section.
A 2L container for distilled water, where tissue sections are “stretched” to remove wrinkles.
An inclined, wear-resistant surface designed to drain excess water and rapidly dry up to 60 sections.
To increase the heating efficiency of the flotation bath.
Objective: To properly flatten, adhere, and dry paraffin sections onto glass slides using the integrated system.

SUMMARY:
The water flotation bath and dryer is an integrated system designed for efficient spreading, drying, and curing of paraffin-embedded tissue sections used in histology and pathology labs. It combines a heated water bath for wrinkle-free ribbon flotation, a drying surface for secure slide adhesion, and an oven for final curing in one compact unit.
All three modules operate within a temperature range of 0Ā°C to 75Ā°C or 0Ā°C to 99Ā°C. The flotation bath has a 2.0-liter capacity for smooth section spreading, the dryer accommodates up to 60 slides on a beveled surface for effective drainage, and the oven holds six slide racks for up to 180 slides.
The system enhances workflow efficiency, saves bench space, and supports high-throughput slide preparation. It ensures consistent results by standardizing the flotation, drying, and curing processes within a single unit.
It is suitable for moderate to high-volume histology laboratories requiring precise and reliable performance. Users should follow proper temperature settings and safety procedures to ensure high-quality slide preparation and operator safety.
The CS-RD-2018 is a processing and preparation instrument; therefore, it does not generate direct analytical data. The primary “data” that is evaluated is the quality of the final product (the slide), which is subsequently analyzed under a microscope.
Quality Parameters to Evaluate (Output Data):
Section Integrity: Absence of wrinkles, folds, or tears in the tissue.
Tissue Adhesion: The firmness with which the tissue is adhered to the slide, preventing lift-off during subsequent staining procedures (H&E, IHC).
Consistency: Uniformity in the stretching and drying of the sections, achieved through the equipment’s precise temperature control.
The quality of the slide preparation is a critical factor that directly impacts the validity and interpretation of histological data (microscopic images and measurements).
The combination flotation bath and dryer is a de facto standard in modern histopathology laboratories. Reference literature in histotechnology, such as the National Society for Histotechnology (NSH) manual or Bancroft’s texts, emphasizes the necessity of precise temperature control.
Scientific Context: Temperature control is vital for:
Flattening: Keeping the bath water just below the paraffin melting point allows for stretching without causing distortion or cellular damage.
Adhesion: Oven drying is a necessary “curing” step to form a strong bond between the tissue and the slide. The oven temperature must be high enough to melt the paraffin, but not so high as to damage the tissue’s protein structures (antigens), especially in preparations intended for Immunohistochemistry (IHC). The RD-2018, with its temperature ranges up to 99Ā°C, provides the flexibility to meet the most rigorous adhesion standards.
