What is the chamber size and capacity of the Tuttnauer 3870ELP?
The 3870ELP features an approximately 85-liter chamber, with dimensions around 15 inches wide by 27–30 inches deep, allowing it to accommodate large loads or long instruments. This makes it an ideal autoclave for:
Laboratories sterilizing glassware or media
Clinics handling high instrument volume
Research facilities with mixed load types
What are the preprogrammed sterilization cycles?
The system includes pre-programmed and customizable cycles, typically covering:
Glassware
Plastics
Liquid sterilization (multiple modes)
Biohazard or waste loads
Users can create and store custom cycles (up to ~16 or more depending on configuration) for specific applications.
Does the 3870ELP include drying functionality?
Yes. Many Tuttnauer 3870-series models include a closed-door active drying system, which:
Circulates filtered hot air
Improves drying efficiency
Maintains sterility after cycle completion
This is especially important for wrapped instruments and porous loads.
How long does a sterilization cycle take?
The sterilization cycles are relatively fast, and while typical cycle times vary depending on load and temperature most fall into the following ranges:
Hot start cycles: ~20–25 minutes
Cold start cycles: ~30–35 minutes
Liquid cycles may take longer due to heating and cooling requirements.
Is the Tuttnauer 3870ELP suitable for laboratories?
Yes! This model is designed primarily for lab use and is widely purchased by:
Life science laboratories
Pharmaceutical and biotech environments
Clinical and research settings
Its repeatable performance, programmable cycles, and compliance with sterilization standards make it suitable for regulated environments.
What the difference between the 3870ELP and other 3870 models?
Key differences include:
ELP (programmable electronic control) vs. manual or semi-automatic versions
Advanced multi-color control panel and digital interface
Greater data tracking and customization options
Compared to manual models, the 3870ELP offers significantly more automation and monitoring capabilities.
What maintenance does the autoclave require?
Routine maintenance is essential for keeping performance up to standard and improving the longevity and continued operation of the machine. This includes:
Cleaning the chamber (e.g., with autoclave cleaner)
Checking door gaskets and seals
Draining and refilling water reservoir
Replacing filters (if equipped)
Preventative maintenance helps extend lifespan and maintain sterilization reliability.
