Heidolph Hei-FLOW Ultimate 120 Peristaltic Pump Accurate dosing is particularly important in the pha (more)rmaceutical, cosmetic or food sector. Comprehensible process conditions are a prerequisite for the safe conveyance of sensitive media. This is ensured by a control accuracy of ±1% and precise speed adjustment (5 — 120 rpm). In addition, an optional foot switch allows the pump to be operated in closed exhaust hoods. The parameters - speed, direction of rotation and on/off function - can be controlled externally either through the analog or digital interface. In this model, you can choose between a single-channel or multichannel pump head. Flow rates vary depending on the pump head: the single-channel head has a flow rate of 0.38 — 813 ml/min; for the multi-channel head 0.005 — 364 ml/min. Depending on the focus of the process, the following parameters can be set on the device: Speed, tubing diameter, flow rate display, metering volume, interval dosing and break times. The pump can be calibrated for optimum dosing results.

The PowerPac Basic power supply is designed to provide constant voltage or current electrophoresis a (more)pplications. The power supply operates at the value specified for the constant parameter, with limits for the other parameters. To prevent damage to the electroferese cell, the PowerPac Basic provides automatic crossover to constant current or constant voltage depending on which set limit is first reached. If the set limit of the non constant parameter is reached, the power supply will switch, making the limiting non constant parameter the new constant. Output specifications: Voltage: Adjustable from 10 to 300 volt, in 1 volt increments Current: Adjustable from 4 to 400 mA, in 1 mA increments Power: 75 W

The X-CLARITY Tissue Clearing System is an all-in-one, easy-to-use solution for electrophoretic tiss (more)ue clearing. Its unique design accelerates the removal of lipids from tissues while preserving the structural integrity of the sample. In ETC (electrophoretic tissue clearing) mode, platinum-plated electrodes generate an electric field to accelerate the removal of lipids from tissues in a highly effcient manner. A temperature control system actively cools and heats buffer to maintain consistent buffer temperatures during clearing. Buffer is constantly circulated to ensure consistent buffering capacity, temperature control, and elimination of tissue clearing byproducts. This advanced system ensures effcient, rapid, and consistent tissue clearing. Voltage: Not adjustable, max 60 V Current: 0.2 – 1.5 A, 0.1 A increments Temperature: 35 – 60°C, 1°C increments Switching time: 0 – 600 min, 10 min increments Pump speed range: 0.1 – 100 rpm, 0.1 rpm increments
