Micro-SteelHeart
The SH Micro-pump head is specifically designed to fill volumes in the 10 – 100 µ liter range.
The user-friendly tubing installation is a unique single-tube insertion (not the more typical “Y” tube design as usual in the larger pump heads).
The fill volume is controlled using a Capmatic developed linear regression algorithm that predicts the number (or partial) revolutions that the pump must make to achieve the required fill. This pump is installed into an automated machine where the weight of the fill is accurately recorded using a very high-resolution scale. The results taken from the scale at each fill are used to adjust the pump revolution as needed to keep the fills within the desired fill tolerance range.
The SH Micro-pump can accept 0.5mm (0.019”) – 0.8mm (0.031”) ID silicon tubing.
Filling accuracy is expected to be within +-5%* of the target dispense volume.
*Published accuracy established from fill tests using water.
• Accuracy depending on the fill volume, tip size selected, product, and /or set up in the order of 1.5% – 5%
• Pump body designed to suit industry standard 0.5mm bore x 1.6mm wall silicon tubing
• Proprietary stainless-steel roller design
• Independent servo motor drive programable directly from the machine HMI
• Self-adjusting tube clamping system
• Drip prevention feature, a.k.a. "Suck Back."
• 316 Stainless steel construction Possibility to connect to an auto compensation feature (If purchased with a TFW (Tare/Fill/Weigh) capabilities scale options) Possibility to connect to an auto compensation feature (If purchased with a TFW (Tare/Fill/Weigh) capabilities scale options)
