Chemyx High-Pressure Syringes – Maximum Pressures

Chemyx Stainless Steel Syringes can be used with the Fusion 4000-X and Fusion 6000-X models. The table below shows the maximum pressure for each Stainless-Steel Syringe compatible with the following Chemyx syringe pumps. These values are theoretical calculations based on the formula found in the following article – “How To Calculate Syringe Pump Pressure“.

Syringe Size I.D. Inner Diameter (mm) Fusion 4000-X Approximate Max Pressure (psi)* Fusion 6000 Approximate Max Pressure (psi)*
6mL 9.53 760 4000
10mL 12.6 430 3000
20mL 19.13 180 1100
50mL 28.6 80 510
100mL 34.9 390
200mL 44  – 250
300mL 54  – 150

*Note – Proper syringe O-rings need to be utilized if there is a leakage to achieve maximum pressures. Lubricating guide rods, lead screw, and proper maintenance is required to reach maximum pressures. Buna-N has a durometer rating of medium-hard. For higher pressure syringe pump applications, a hard/very hard O-Ring (PTFE) needs to be utilized.

This is measured data

*Warning do not use any of the Chemyx Syringe Pumps for high-pressure gas applications.
