for Insect Stylectomy

A brief RF pulse of about  20 watts is delivered via a fine tungsten needle to give a highly localized burn.  It can cut the stylet or labium of a grazing aphid, or cauterize other tissue, in a volume according to the thermal properties of the tissue and the geometry of the needle. The Zapper is in routine use in laboratories world-wide.

RF micro-cautery gives a versatile, reliable and inexpensive method to collect sieve tube sap.

Power is provided for sharpening needles.  


A version is available that can be powered by a 12v battery (as well as 110 or 230vac)
