Description
PVC bulb size 11 for 347 ml pipettes is a robust laboratory suction bulb made of PVC for controlled handling of larger liquid volumes. Designed expressly for 347 ml pipettes, it provides a bore diameter of 6 mm and a ball diameter of 94 mm that together deliver a secure connection and strong vacuum for aspiration and dispensing. The flexible yet durable PVC construction allows comfortable manual operation while resisting many routine laboratory chemicals, serving as an effective Peleus-style safety bulb and macro-pipetting aid. This configuration helps laboratories avoid mouth pipetting and maintain safer working practices during high-volume transfers. Supplied as one piece from manufacturer Witeg and weighing 0,151 kg, the bulb integrates readily into existing pipette procedures and endures repeated cleaning. Its smooth spherical geometry and consistent wall thickness promote reliable day-to-day performance in analytical chemistry, biology and quality-control settings. Facilities that need a dependable accessory for 347 ml capacity pipettes will find this size 11 PVC bulb a practical choice for everyday liquid-handling tasks.

Questions about Suction bulb, PVC, size 11, for 347 ml p
What is this article?
Suction bulb, PVC, size 11, for 347 ml p is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Single-channel pipettes, inside Liquid handling, in Lab instruments.
A single-channel piston pipette delivers one volume through one tip. Fixed-volume pipettes are more accurate at their one volume. Variable pipettes cover a range and are specified at several points in it. Air displacement fails on viscous and volatile liquids.
A piston pipette delivers a set volume of liquid by air displacement or, for viscous and volatile liquids, by positive displacement. A single channel is the ordinary tool. A multichannel repeats the same volume across a row of a plate. A bottle-top dispenser meters reagent from the bottle it sits on. The accuracy is a property of the pipette and of how it is used, which is why calibration and a certificate exist. Piston-operated apparatus is treated under ISO laboratory apparatus. The volume unit sits with the BIPM and NIST.
