The Univentor 864 Syringe Pump is a high precision instrument designed for microdialysis, microinjections and infusions, 0,001µl-5ml/min. The Univentor 864 syringe pump offers a wide range of possibilities. The U-864 comes with a unique computer controlled pulse-free DC motor that ranges from 3-3000 rpm providing an extremely high precision.
The most common syringes are pre-programmed but any syringe within clamping range may be used. There are three interchangeable syringe holders available so that either 4 syringes up to 50mL, 6 syringes up to 10mL or 8 syringes up to 2.5mL can be used simultaneously. Fitted with syringe holders for a total of 4 syringes the Univentor Withdrawal Adaptor can be used to enable withdrawals as well as simultaneous infusions and withdrawals.
The built-in computer makes the U-864 self-calibrating and takes care of all the calculations needed to keep control of flow rates and delivered volumes for different sizes and types of syringes. The control panel is self-explanatory and user friendly with a short operating instruction. During operations the settings remain visible and the delivered volume is continuously displayed. The last settings are stored as default values.
RS-232 and TTL logic interface is incorporated and the U-864 can be programmed to start, stop, wait, change flow rate and to start/stop external instruments such as the U-820 Microsampler or valves. The pump has a limit switch to automatically stop the motor when the syringes are empty to protect the syringes and the instrument.
