Delivering picoliter volumes precisely

With UMP3's smooth tuning for precise sample delivery or extraction, you can be confident in your system to handle all of your low-volume applications.  

Options

Note on Accessory

*13142 is the foot pedal for use with the MICRO2T/MICRO4T ONLY. It is not compatible with our older MICRO4 controller, which uses the 15867 foot pedal. The two foot pedals are not cross-compatible. 

Benefits

• Accepts a wide range of microinjection syringes from 0.5 ul to 1000µL.
• Manual or automated functionality
• Smooth and low-noise operation 
• Mounts directly on micromanipulator or stereotaxic frame
• Nominal injections down to 1 nL/min
• Rapid setup with intuitive touchscreen controller
• Premium Warranty Available

Applications

MicroFluidics

• Accurate microinjection of solution into tissue
• Cannulation drug delivery
• Micro delivery of biochemical agents or dyes
• Intravitreal Injection (with RPE-KIT)
• Intraoccular Injection (with IO-KIT)

The UMP3 (UltraMicroPump3) is a versatile microinjection syringe pump which uses NanoSyringes to deliver picoliter to milliliter volumes. The UMP3 is optimal for applications requiring precise, targeted injections of  extremely low-volume samples. With its touchscreen controller, our UMP3 can deliver or withdraw as little as 0.53µL/step (using 10µL syringe with 60 mm scale length).

Patent Pending Technology

The MICRO2T SMARTouch™ controller for the UMP3 and NANOLITER2020 features Patent Pending technology which includes:

• Total system calibration – Calibrate the syringe and the controller together as a system. This feature eliminates variability of the syringe and delivers (or withdraws) the configured volume.
• Smart smoothness – The controller can be set to automatically adjust microstepping according to the injection rate to deliver (or withdraw) smoothly. 
• User defined travel limits – Set the limits for your NanoSyringe on your MICRO2T. This prevents your UMP3 from exceeding its drive range, potentially resulting in damaging your syringe, or stalling your UMP3 motor. 

Additional Features

The MICRO2T SMARTouch™ controller has a graphical indication of the rate and volume remaining in your NanoSyringe. It offers end-stop detection that is dependent on the syringe volume. You can control two pumps independently the MICRO2T's dual capability. The controller also has automatic pump detection and a Pause/Resume feature for incremental dosing during infusion, or sample collection upon withdraw. The MICRO2T SMARTouch™ controller is fully compatible with all previous models of the UMP3. 

Flexibility in Mounting

For positioning, the UMP3 microinjection syringe pump may be attached to any of several WPI micropositioners such as the M3301 (manual), DC3001 (motorized) and most stereotaxic manipulators.

Computer Control— A USB port on the rear of the MICRO2T controller can be used for connecting to a computer for scripted protocols.

NOTE: UMP3 accepts glass syringes with barrel diameters from 5.5 to 9 mm. You MUST set end-stop positions on your MICRO2T prior to using your UMP3.

Application Notes

The following images depict the various setups for microinjection using the UMP3 syringe pump and the MICRO2T controller.  *Parts are interchangeable

The RPE Kit is designed for retinal pigment epithelium injections in the eye using a NanoFil^TM syringe mounted on the UMP3 microinjection pump. You will be able to achieve accurate, and repeatable injections down to the submicroliter range.
