Abstract

1439659 Pipette W E GILSON and R E GILSON 26 July 1973 [24 Oct 1972] 35724/73 Heading B1X An adjustable pipette comprises in combination: an elongate body defining a barrel portion and a plunger cavity adjacent a forward end of said body; a plunger unit mounted for reciprocation in said body and having a plunger portion extending from said barrel portion into said plunger cavity and an operating portion extending rearwardly out of said body; a seal assembly carried by said body in sealing relation with said plunger portion; said plunger unit having plunger unit stop engaging means permanently mounted thereon and disposed within said barrel portion; a forward stop in said body engageable by said stop engaging means upon forward reciproation of said plunger unit to a forward stop position thereof; an internally rotational nut fixed in said body against rotational and axial movement; a hollow threaded shaft extending through said nut and having a forward end disposed within said barrel portion and a rear end extending rearwardly out of said body; said operating portion of said plunger unit extending through said shaft; rear stop means reciprocable with the forward end of said shaft upon rotation of said shaft in said nut and engageable by said stop engaging means upon rearward reciprocation of said plunger unit to a rear stop position; and an indicator arrangement in said body keyed to said shaft, said arrangement being arranged to provide an indication in response to rotation of said shaft indicative of the position of said rear stop. As shown, the plunger unit 14 engages forward stop 78 and adjustable rear stop 116. The forward stop 78 is displaceable against an overtravel spring 80 so as to allow complete emptying of the pipette.
