Common Medical Labware
Laboratory equipment includes tools specifically designed for carrying out critical measurements, analyses, testing of the various parameters involved with human biological conditions and health factors. These are manufactured under strict scientific supervisions and thus maintain highest level of safety standards.Medical laboratory procedures heavily depend on various types of glassware or lab wares (as many of them are not made of glass but plastic) for checking and measuring critical fluid parameters.
Let’s study the presence and utility of a few lab ware items:
Beaker: These are broad-mouthed, parallel-sided containers with a short extended pouring spout end at its rim. They normally have embedded graduations for determining the volume of the contained liquids and fluids.
Erlenmeyer flasks: These are typically flat bottomed with sloping slides. The basic shape is conical with a top terminating into a bottle neck shaped opening. They are available in ranges of 10 to 4000ml and used for holding and mixing liquids, solutions and for measuring less critical volumes through the markings printed on their side surface.
Florence Flask: It is a flat bottomed container with a bubble shaped body and a protruding bottle neck shaped top, having more or less same use as Erlenmeyer flask.
Volumetric Flask: It has a pear-shaped body with a rather long bottle neck shaped top outlet. It is used for measuring the volume of fluids whose values require critical measurements.
Graduated Cylinders: These are long, parallel straight-sided, transparent upright containers with calibrated graduations. Its chamfered base facilitates better standing stability. Measurement of fluid volumes done with it are normally non critical and typically used to store and monitor 24-hour urine specimens.
Pipets: Pipets are primarily used for measuring and transferring liquids. Basically they are classified in following two types:
Volumetric Pipets: These are narrow long tubes with a uniform bulge at the center, broader opening at one end and tapering at the other end. They are used for holding and transferring critically accurate volumes of a particular liquid. The marking TD over them indicates they are capable of transferring a particular volume of liquid within a particular specified time limit.
Graduated Pipet: These are long slender tubes uniformly graduated throughout their entire length. Its one end is tapering and the other end terminates into a narrower neck opening. Usually they are TD marked and are used accommodate and transfer a particular volume of liquid in it as per the calibration. The serological pipet is one commonly used graduated type of pipet.
