Bath Circulator — Used Huber Ministat 240 (Huber)

How Much Does Used Huber Ministat 240 Cost in 2026?

The used Huber Ministat 240 typically sells in the range of $8,500, with no significant variation based on condition grade. Units in condition grade B, which is common for this model, are most frequently listed in this price range. Refurbished units from vendors like Ferrotec and Axus Technology are commonly priced within this bracket, with Axus occasionally listing units at $8,500 for units with less than 10,000 operating hours.

Compared to a new unit, which can cost between $18,000 and $22,000, the used Huber Ministat 240 offers a savings of 40–60%. This makes it a cost-effective alternative for labs and semiconductor facilities that need a reliable bath circulator without the premium of new equipment.

However, it’s important to note that a failed or poorly refurbished unit can lead to downtime of 2–4 weeks during replacement or repair, which can cost a facility up to $15,000 in lost productivity. Always verify the unit’s operating hours and maintenance history before purchase.

Used Huber Ministat 240 Specifications and Compatible Tools

The Huber Ministat 240 is a benchtop bath circulator designed for precise temperature control in the range of -20°C to +150°C. It typically features a recirculation pump with a flow rate of 1.5 L/min and a bath capacity of 2.5 liters. The unit commonly uses a Peltier-based heating/cooling system, which allows for fast temperature changes and stable operation.

This model is typically found in semiconductor process chambers, especially in older systems like the Lam Research Centura series from the early 2000s. It is also compatible with certain Applied Materials and Veeco tools that require a bath circulator with a -20°C to +150°C range.

However, it is not compatible with newer systems that require a higher flow rate or a larger bath volume, such as the Lam Research Nova series. Attempting to use the Ministat 240 in these systems can lead to overheating and failure, potentially damaging the process chamber and costing $20,000–$30,000 in repairs.

What to Check Before Buying a Used Huber Ministat 240 in 2026

1. Verify Operating Hours: Units with more than 12,000 hours of operation are at higher risk of pump and Peltier failure. A unit with over 15,000 hours should be rejected outright.

2. Test the Pump and Circulation: Use a flow meter to confirm the unit delivers at least 1.4 L/min. If it drops below 1.2 L/min, the pump may be failing, which can lead to uneven temperature distribution and process errors.

3. Check the Temperature Range: Perform a step test from -20°C to +150°C. The unit should stabilize within ±0.5°C. If it exceeds ±1.0°C, it may not be suitable for critical processes.

4. Inspect the Peltier Module: Look for signs of thermal cycling damage, such as cracked solder joints or warped heat sinks. A damaged Peltier module can fail within 6–12 months, causing a complete system shutdown.

5. Confirm Production Year: Units produced before 2012 may use older Peltier modules that are no longer supported. A failure in these units can cost $10,000–$15,000 in replacement parts and downtime.

FAQ

Q: Can I use the Huber Ministat 240 in a new Lam Research Nova system?
A: No. The Nova system requires a minimum flow rate of 2.0 L/min and a larger bath volume. The Ministat 240 has a 1.5 L/min flow rate and a 2.5 L bath, which is below the required threshold and can lead to overheating and system failure.

Q: Should I buy a Huber Ministat 240 with over 15,000 hours?
A: No. Units with over 15,000 hours are at high risk of pump and Peltier failure. A failure can lead to a 2–4 week downtime and $10,000–$15,000 in repair costs. Stick to units with under 12,000 hours.

Q: How long can I expect a used Huber Ministat 240 to last?
A: With proper maintenance, a unit in condition grade B can last 3–5 years. Regularly checking the Peltier module and pump performance every 6 months can extend its life and prevent costly failures.

Q: What’s the difference between a used and refurbished Huber Ministat 240?
A: A used unit has not been professionally serviced, while a refurbished unit has been tested and repaired by vendors like Ferrotec or Axus Technology. Refurbished units typically come with a 1–2 year warranty, whereas used units may have no warranty at all.

Q: How much does it cost to repair a failed Peltier module in a Huber Ministat 240?
A: Repairing or replacing a failed Peltier module can cost between $3,500 and $5,000, depending on the vendor and whether the module is still in production. Units with older modules may require sourcing from secondary markets, which can increase costs.
