For injecting or withdrawing precise fluid volumes

Stoelting’s Manual Microsyringe Pump is a convenient instrument when using visual feedback to determine the amount to be infused or withdrawn. It also provides an economical means for any application requiring injecting/withdrawing a calibrated volume under manual control.

Applications
The Microsyringe Pump has numerous applications:

• ICSI microtitration 
• Chromatography
• Microinjections

For example, for microinjection, precise placement in brain tissue is obtained by mounting glass pipettes on the electrode carrier of a stereotaxic instrument. The output is conducted from the syringe to the tissue through PE tubing.

Two Models Available

1. The 51222 Modelcan be used for infusion or withdrawal with syringes 25 µl or larger. A special micrometer with a non-rotating barrel and a clamp binds the syringe plunger to the micrometer.
2. The 51218 Model has a rotating barrel micrometer that can only be used for infusion.

Delivers Precise Fluid Volumes
The Starrett® micrometer used is graduated in 0.010 mm increments. The syringe (included) is a Stoelting 51115S with standard male Luer connector, accurate to 0.01% of graduated volume.

Accommodates Most Syringes
Stoelting’s Microsyringe Pumps accommodate a range of syringes and microsyringes, such as those below, to enable a wide range of volumes to be delivered. For more information on our microsyringes go to: Stoelting Microsyringes, Hamilton Microsyringes or All Microsyringes.

Digital Micrometer Option
The 51218 for infusion only, is available with a digital micrometer for convenient digital readings in microns.  Also may be read in inch units. Connection to a computer for automated recording of dose injected is possible.

Accessories Included
The Microsyringe Pumps come with one 100 Microliter syringe, 1 female Luer Lock-to-tubing adaptor and 10 ft. of Intramedic® PE polyethylene 60 tubing, .030" I.D., x .048" O.D.
