Laboratory Mixing Extruder — Used Dynisco LME-120 (Bidservice)

How Much Does Used Dynisco LME-120 Laboratory Mixing Extruder Cost in 2026?

As of July 2026, the used Dynisco LME-120 Laboratory Mixing Extruder is priced at $12,500 for a unit in condition grade B. This price typically reflects a unit with moderate wear and a full refurbishment by vendors like Axus Technology or Ferrotec. Units in better condition (grade A) may command up to $14,000, while those with more significant wear (grade C) can be found for as low as $10,000. Compared to a new LME-120, which can cost upwards of $30,000, buyers can expect to save between 40–60% by purchasing a used unit.

The cost of failure to acquire a reliable used unit can be steep. A delay in sourcing a replacement extruder can halt R&D or quality control operations, costing a lab up to $5,000 per week in downtime. It’s also worth noting that units with more than 10,000 operating hours may have reduced performance and higher maintenance costs. Always verify the condition and refurbishment history with the seller before committing.

Used Dynisco LME-120 Laboratory Mixing Extruder Specifications and Compatible Tools

The LME-120 is a bench-top laboratory mixing extruder with a 120-gram capacity, commonly used for testing polymer blends and additives. It features a single-screw design with a typical screw diameter of 19 mm and a L/D ratio of 20:1. The extruder typically operates at temperatures between 150°C and 350°C, with motor power ranging from 1.5 to 2.2 kW. It is often used in conjunction with Dynisco’s melt flow indexers and other polymer characterization tools.

The LME-120 is typically found in use from 2010 to 2018, and units with more than 12,000 operating hours may require more frequent maintenance. It is compatible with older Dynisco control systems and some third-party temperature controllers, but not with newer models like the Dynisco 9000 series. Attempting to use a newer control system with the LME-120 can result in communication errors and system instability, potentially causing data loss or incorrect test results.

What to Check Before Buying a Used Dynisco LME-120 Laboratory Mixing Extruder in 2026

1. Operating Hours and Age: Look for units with less than 10,000 operating hours and manufactured after 2012. Units older than 2010 may have outdated components that are no longer supported.

2. Motor and Drive Condition: Run a load test to verify motor performance. If the motor draws more than 1.5 times the rated current under load, it may be failing. A failed motor can cost $2,000–$4,000 to replace and can lead to downtime of 3–5 days.

3. Screw and Barrel Wear: Inspect the screw and barrel for scoring or pitting. Use a micrometer to check the screw diameter. A deviation of more than 0.05 mm indicates significant wear and can lead to inconsistent mixing results.

4. Control System and Sensors: Test the temperature control system with a known reference. If the system cannot maintain a stable temperature within ±2°C, it may need recalibration or replacement, which can cost $1,500–$2,500.

5. Refurbishment History: Reject any unit that lacks a documented refurbishment history or was not serviced by a reputable vendor like Axus Technology or Ferrotec. A lack of service records can lead to unexpected failures and repair costs.

FAQ

Q: Can I use the LME-120 with a newer Dynisco control system?
A: No. The LME-120 is not compatible with the newer Dynisco 9000 series control systems. Attempting to use them together can cause system errors and incorrect test results, leading to rework costs of $1,000–$2,000 per batch.

Q: Should I buy a used LME-120 with over 10,000 operating hours?
A: It’s not recommended. Units with more than 10,000 hours often require more frequent maintenance and may have reduced throughput. Expect to spend an additional $1,500–$2,000 annually on repairs and downtime.

Q: How long can I expect a used LME-120 to last with proper maintenance?
A: With regular maintenance and less than 10,000 operating hours, a used LME-120 can last 5–7 years in a lab setting. Units with more than 12,000 hours may only last another 2–3 years.

Q: What is the difference in cost between a used and new LME-120?
A: A used LME-120 typically costs $12,500, while a new unit can cost up to $30,000. This represents a savings of 40–60%, depending on the condition and vendor.

Q: How much does it cost to replace the screw and barrel if they are worn?
A: A replacement screw and barrel can cost between $3,000 and $5,000. If not replaced in time, inconsistent mixing can lead to failed batches and rework costs of $1,000–$2,000 per incident.
