	Micromachined Pipette Arrays (MPA)
		The micromachined pipettes have many advantages over the current micro pipette technology: they're capable of performing highly parallel manipulation of samp1es/reagents, the capability to precisely define the pipette dimensions allowing for small volumes (pL to JLL range), and a wide range of pipette center-tocenter spacing (centimeters to 50 JLm).
		The thick photoresist is used to precisely define the inner dimensions of the pipette and serves as a thick sacrificial layer to be removed later in the process (Figure 2c).
		The main advantages of the micromachined pipette arrays are: (a) uses low temperature processes, (b) is compatible with standard IC fabrication technology, (c) uses batch fabrication techniques, (d) allows fluid transfers in the sub-p-L range, and (g) serves as an interface between macro scale and micro scale instrumentation.

	Pipette \| World of Microbiology and Immunology
		A pipette is a piece of volumetric glassware used to transfer quantitatively a desired volume of solution from one container to another.
		Pipettes are calibrated at a specified temperature (usually 68°F [20°C] or 77°F [25°C]) either to contain (TC) or to deliver (TD) the stated volume indicated by the etched/painted markings on the pipette side.
		Dropping pipettes (i.e., medicine droppers) and Pasteur pipettes are usually uncalibrated, and are used to transfer liquids only when accurate quantification is not necessary.

	Pipette \| World of Chemistry
		Pipettes that are marked TD generally deliver the desired volume with free drainage; whereas in the case of pipettes marked TC the last drop must be blown out or washed out with an appropriate solvent.
		The accuracy and precision of the smaller Class A pipettes and of the Class B pipettes are less.
		Mohr and serological pipettes have graduated volumetric markings, and are designed to deliver various volumes with an accuracy of +/- 0.5-1.0 %.

	Proper Pipette Usage
		Pipettes are calibrated assuming this small amount of liquid that remains because of surface tension.
		Typical serological pipettes used in microbiology labs are "blow-out" pipettes where the gradations of volume inscribed in the side of the pipette include the volume to the tip; touching the pipette end to the side of the container will help the liquid exit the pipette by breaking the surface tension of the liquid.
		Other pipettes do not include the volume at and about the tip in the gradations on the side of the pipette, instead rely on the movement of the meniscus between two identified points on the gradations to determine the volume delivered.

	Ovation BioNatural Pipette (Site not responding. Last check: )
		Although it may be impossible to avoid certain arm, wrist and hand movements due to the nature of the work, using a pipette that minimizes rotation and deviation and thereby reduces stress on the muscle group is recommended.
		From an ergonomic perspective, when jamming a pipette into a tip, the user typically exerts a level of force that is well beyond the pipette’s intended design.
		Because the tip is forced onto the pipette, the user needs to apply additional force to the tip ejector mechanism, further exacerbating contact stress on the thumb and increasing exertion by the thumb muscles.

	Epstein - Forensic Science Communications - October 2003
		Pipettes are complex precision instruments subject to error due to mechanical failure and improper operator technique.
		Pipette B is a 100-1000µL variable-volume pipette set to deliver only 10 percent of its maximum volume, or 100µL. Degraded precision is seen even though it delivers close to the 100µL target volume.
		Pipettes fail for a reason, and it is desirable to identify the cause of the failure before attempting to fix it by adjusting the device.

	Liquid dispensing apparatus including means for loading pipette tips onto liquid dispensing cylinders and maintaining ...
		What is desired therefore is to provide a compact, relatively lightweight apparatus for securing pipette tips to their associated cylinders, a load being constantly applied to the pipette tips whereby an effective seal is continuously maintained during the entire operation cycle of the apparatus to avoid leaking and contamination of the fluid.
		The pipette tips 20 are under constant load throughout the operating cycle of the apparatus to ensure an effective seal between the pipette tips and cylinders.
		In this case, as arm 52 of actuator 50 retracts to the position illustrated, plate 48 is moved towards loader plate 54, causing pipette tip plate holder 16 and pipette tip plate 18 to move lower with respect to cylinder mounting plate 30 to the position illustrated, removing pipettes 20 from their associated cylinders 26.

	Lab Safety Supply - EZ Facts Safety Info - Document #292, Pipette Calibration
		For adjustable pipettes, you may choose to do the nominal volume, approximately 50% of the nominal volume and/or the smallest adjustable volume which should not be less than 10% of the nominal.
		Fixed-volume pipettes and bottletop dispensers are calibrated at the nominal volume and multichannel pipettes are calibrated at the nominal volume and smallest adjustable volume.
		You will want to consider maintenance when a pipette fails calibration and determine if the pipette is to blame and take into consideration how much it is being used and what works for your lab in the long run to consistently get good data.

	Definition of Pipette
		A pipette is a glass tube used for the delivery of a measured quantity of liquids.
		A Pasteur pipette is a cotton-plugged glass tube drawn out to a fine tip, used for the sterile transfer of small volumes of fluid.
		Modern pipettes, sometimes called Gilson pipettes, often use a mechanical plunger and can be calibrated to deliver a fixed amount of liquid with each stroke.
