Seller: 56fallsrus (1,865) 100%, Location: Berwyn, Illinois, Ships to: US & many other countries, Item: 264531426617 This piece of equipment was very lightly used and is in excellent condition, fully tested and functions like factory new.The Gravipull-3 is designed to pull multi-barrel glass micropipette assemblies or single-barrel glass micropipettes. It is intended to soften and pull borosilicate glass capillary tubing constructions (‘blanks’) up to 0.25" (6.4 mm) in diameter and 6" (152 mm) long. The pull is fed by gravity using a 7-stage weight system. The chuck mounted on the lower sliding shaft can be rotated and it is pulled by the weights once the glass begins to soften. A bumper in the bottom of the puller arrests the lower glass holder gently so as not to damage the lower piece of glass.A truly unique feature of the Gravipull-3 is the capability of pulling micropipettes in two stages using two separate heater coils and an exceptional latch mechanism. For greater flexibility, the heater coils and the bumper/latch system are mounted on two carriages allowing vertical adjustments. Adjustable shaft collars allow reproduction of the same pull sizes in repetition with ease. Altogether, this system permits producing taper (shank) lengths up to about 100 mm.A sample two-stage pull of a three-barreled micropipette assembly is shown on the left. This long-tapered version of our Carbostar-3 microelectrode is intended for reaching deep brain structures in large-bodied animals. A video on how to use this puller is shown here.Main specificationsSlider’s travel:4.4" (112 mm) vertical, the longest in its class!Pulling force:Gravity-fed set by weight discs in 7 stagesHeater power:12 VDC, 20 A, max., by pulse width modulationHeaterwire:Kanthal AF, from 17 AWG to 20 AWG recommendedDisplay:LCD to show heater currents in AmperesWork light:12 V LED lampMains power input:World-wide automatic, self-adjusting: from 85 to 265 VAC, 280 W, max.Mains frequency:From 47 Hz to 63 HzDimensions:8.3" x 12.2" x 25.6" (W x D x H) (21 cm x 31 cm x 65 cm)Net weight:22 lbs (10.0 kg)Shipping weight:35 lbs (16.0 kg) Condition: Used, Condition: Excellent, Brand: Kation Scientific, Intended Use/Discipline: Biological Laboratory
