Harbo Large Capacity Syringe
Harbo Syringe The Harbo syringe simplifies the handling, storage and shipment of semen. It also increases efficiency in commercial production and provides convenience for the specialized needs of researchers. In need of a method to store and accurately measure semen, this syringe was designed by Dr. John Harbo, of the United States Department Of Agriculture in Louisiana, USA.
It is highly recommended, regardless of the instrument used and is compatible with all instruments featured here.

Precise Measurement Of Semen Volume

The calibrated micrometer enables delivery of very accurate and readable measurements. The 200 microliter (µl) capacity of the syringe is marked with divisions of 0.2 µl. This provides precision in the insemination of specific amounts of semen. For example, several queens can be inseminated with specific amounts of semen from one drone or one queen can be inseminated with homogenized semen from a hundred or more drones. Semen can also be diluting to specific ratios.

Detachable Capillary Tubes Enable For Semen Storage
Semen is collected in easily detachable capillary tubes for shipping and storage. This also enables the efficient collection of unlimited quantities of semen, simplifying semen handling and homogenizing of large amounts.

Detachable Glass Tips
A small piece of latex tubing connects the tip to the capillary tube. This provides flexibility and helps prevent breakage. Glass tips are easily changeable without loss of semen.

Protective Glass Barrel Houses Semen Storage Tube
The capillary tube is encased in a protective glass barrel that is easily assembled and disassembled. The glass barrel fits into the syringe holder of most instruments on the market.

Variety Of Connection Points Provides Convenience
The glass tips and capillary tubes are attached with a small piece of latex tubing. Tygon tubing connects these to the micrometer. These connections allow for easy and quick change of tips and semen storage tubes. The connections also allow for adjustment of the saline volume in the syringe, which acts as a liquid plunger, without loss of semen during collection.

Separate Syringe Stand
The micrometer is held in its own separate stand. For production work, the separate stand allows the easy transfer of semen loads between operators.

Recommended For Use With Other Instruments.
The Harbo syringe is recommended for use with the Schley and Swienty instruments for handling and storing semen. These instruments use a piston type syringe with a capillary tube drawn into a glass tip. Semen handling is cumbersome and the capacity is limited to 50 µl to 60 µl. The size of the capillary tube is limited to the allowable distance between the syringe and the queen holder. The exposed, long glass tips are fragile, inflexible and care must be taken in their use.
