Memmert Histology Chambers
Memmert histology chambers, also called paraffin ovens (UNpa), maintain homogenous temperature and humidity, ideal for storing paraffin wax and tissue samples at stable temperatures. Features include:
- 5 model sizes (32 to 161 L volume)
- Temperature range +30 °C to +80 °C
- Model variant: TwinDISPLAY
- High degree of thermal safety through multiple overtemperature protection
- No feed or exhaust air, therefore an almost gas-tight chamber
Model Guide

UNpa
Natural Convection Paraffin Oven
Designed for safety, high-precision temperature control of embedding medium like paraffin or wax.
How Memmert Histology Chambers Support Lab Workflows
Consistent temperature and humidity are critical throughout tissue processing, embedding, and slide preparation. Even small fluctuations can affect paraffin consistency and, in turn, the quality of the sections a histology lab produces.
Applications for Histology Chambers
- Paraffin wax storage and melting
- Tissue processing and embedding preparation
- Slide and specimen storage
- Pathology and diagnostic lab workflows
Why Gas-Tight Design Matters
Because histology chambers have no feed or exhaust air, they stay almost fully gas-tight, which helps hold a stable internal environment and keeps paraffin and samples free from unwanted airflow or contamination.
Choosing a Histology Chamber
Consider your required chamber volume within the 32 to 161 L range, confirm the +30°C to +80°C temperature range fits your process, and look at the TwinDISPLAY option if you need to track parallel setpoints along with built-in overtemperature protection for sample safety.
