{"product_id":"easdcepsp","title":"Economic Programmable Syringe Pump for Slot Die Coater, EASDCEPSP","description":"\u003cp\u003eFor high-precision slot-die coating, a high-pressure syringe pump is the standard delivery system. Unlike a doctor blade where thickness is controlled by a mechanical gap, slot-die coating is a pre-metered process—the wet film thickness is directly proportional to the pump's flow rate and inversely proportional to the coating speed.\u003c\/p\u003e\n\u003cp\u003eTo achieve a uniform, streak-free coating, the syringe pump should meet these technical criteria: (1) \u003cstrong\u003ePulse-Free Flow\u003c\/strong\u003e: The motor must have high micro-stepping resolution. Any \"pulsing\" in the flow will result in visible transverse \"ribbing\" or waves in your dried electrode. (2) \u003cstrong\u003eHigh Torque\/Linear Force\u003c\/strong\u003e: Battery and CDI slurries are often highly viscous (\"peanut butter\" consistency). Standard medical syringe pumps will often \"stall\" or \"slip.\" You need a laboratory-grade pump with at least 20–40 lbs (9–18 kg) of linear force. (3) \u003cstrong\u003eChemical Compatibility\u003c\/strong\u003e: The syringe itself should be stainless steel or glass with a PTFE-tipped plunger. Plastic syringes can swell or leach when used with solvents like NMP (N-Methyl-2-pyrrolidone).\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"height: 201.2px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 35.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eEASDCEPSP (E-A-SDC-EPSP)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eAC110-220V±10%, single phase, 50\/60Hz, ~1 W\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003ePump Pressure Version\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eStandard Pressure, 0.5-60 mL\u003c\/li\u003e\n\u003cli\u003eHigh Pressure, it will provide a double pump force.
