The Cole-Parmer automatic press machine 'X-Press 3636' is a device that produces highly uniform pellets suitable for fluorescent X-ray analysis and infrared spectroscopy by applying a maximum pressure of 35 tons through an automatic hydraulic press. With program settings via a touch panel, it is easy to set detailed parameters for weight pressure, pressure holding time, and pressure release time. This allows for the creation of uniform samples. By using a dedicated die set, it ensures even pressure application on the samples, enabling appropriate sample molding for analytical measurements. Die set sample sizes: 13mm, 31mm, 35mm, 40mm.

Cole-Parmer's KATANAX glass bead production machine and alkaline fusion device offers three models: "K1 Prime (produces 1 piece)", "X-300 (produces 1-3 pieces simultaneously)", and "X-600 (produces 6 pieces simultaneously)." By heating and stirring samples, flux, and release agents in a platinum crucible, and then pouring them into a platinum mold after degassing, it is possible to produce homogeneous glass beads with a good surface condition. Additionally, it allows for safe alkaline fusion. Operation is conducted via a touch panel display, and the fusion conditions can be programmed and saved in the main unit. 【Features】 - Capable of producing homogeneous glass beads with a good surface condition - K1 Prime model produces 1 piece at a time, while X-600 model can produce 6 pieces simultaneously - Uses an electric furnace for the fusion method - Does not require utilities other than power (such as gas or cooling water) - Fusion conditions can be programmed and saved in the main unit *For more details, please refer to the related link page or feel free to contact us.
