LW Scientific Tissue Flotation Bath - FWL-TISS-BTH3 | Lighted Touchscreen PID Control

When paraffin ribbons hit the water and start bunching and folding, every second counts — and imprecise temperature makes it worse. The LW Scientific ReadyWarm Tissue Flotation Bath (FWL-TISS-BTH3) eliminates that variability with a touchscreen PID controller that holds the bath to within fractions of a degree. The LED-lighted, black Teflon-coated interior delivers high contrast so you can see and position every ribbon precisely before mounting — and the compact footprint fits even the most crowded histopathology bench.

Features and Benefits

• Touchscreen PID temperature control — precise digital setpoint management eliminates guesswork and temperature drift during batch processing
• LED-illuminated black Teflon (PTFE) interior — high visual contrast between the dark basin and translucent tissue ribbons makes positioning fast and accurate
• Celsius and Fahrenheit display — switch between units at a glance to accommodate any protocol or international SOP
• Uniform heat distribution — no hot spots or cool zones that cause uneven paraffin relaxation or distorted sections
• Compact benchtop footprint — fits on crowded histopathology workstations without displacing other equipment
• Universal 90–240 VAC power adapter — ready for use in any country without voltage conversion hardware
• Designed and assembled in Atlanta, Georgia, USA — built under ISO 13485:2016 medical device quality management standards

Laboratory Applications

• Floating and flattening paraffin-embedded tissue ribbons before mounting on microscope slides
• Preparation of histological sections for H&E, IHC, and FISH staining workflows
• Cytopathology and anatomic pathology routine slide preparation in hospital labs
• Veterinary pathology tissue processing for diagnostic histopathology
• Research histology labs requiring reproducible, artifact-free tissue sections

Frequently Asked Questions

What is the temperature range of the FWL-TISS-BTH3, and how accurate is it?
The ReadyWarm Tissue Flotation Bath uses a digital PID touchscreen controller to maintain precise setpoint temperatures suited for paraffin flotation — typically 40–50°C. PID control prevents temperature overshoot and drift, keeping the water stable throughout extended batch processing sessions.

What is the benefit of the black Teflon-coated interior?
The dark, corrosion-resistant PTFE coating provides strong visual contrast against translucent paraffin ribbons floating on the water surface. This makes it significantly easier to see each section and position it precisely onto a slide, reducing errors and increasing throughput.

Can distilled or deionized water be used in this bath?
Yes — distilled or deionized water is recommended to minimize mineral buildup on the Teflon interior. Some protocols also add a small amount of albumin solution or similar adhesive to improve section adhesion to slides.

Is the FWL-TISS-BTH3 compatible with international electrical standards?
The included universal 90–240 VAC adapter allows the unit to be used with standard wall outlets worldwide without a separate voltage converter, making it suitable for international labs and research facilities.
