An eye dropper, also called Pasteur pipette or simply dropper, is a device used to transfer small quantities of liquids. [1] They are used in the laboratory and also to dispense small amounts of liquid medicines. A very common use was to dispense eye drops into the eye.
Small rubber bulbs attached to glass and plastic rods, used as dropper. The smaller rubber bulbs are well suited with small pipettes to draw smaller amount of reagents and can attach to both glass, as well as plastic rods. They are very commonly used for droppers as small sized rubber bulbs help control the amount of drops more precisely.
A pipette (sometimes spelled as pipet) is a type of laboratory tool commonly used in chemistry and biology to transport a measured volume of liquid, often as a media dispenser. Pipettes come in several designs for various purposes with differing levels of accuracy and precision , from single piece glass pipettes to more complex adjustable or ...
used in photochemical analysis and quantitative estimation of substances such as blood sugar, creatinine, and hemoglobin. Burette: used to measure the amount of acid or alkali used in titration: General laboratory stands, racks, filter paper, reagents, etc. Induction coils: as a source of high voltage electricity Cathode ray oscilloscope ...
Typical volumes are 1, 2, 5, 10, 20, 25, 50 and 100 mL. Volumetric pipettes are commonly used in analytical chemistry to make laboratory solutions from a base stock as well as to prepare solutions for titration. ASTM standard E969 defines the standard tolerance for volumetric transfer pipettes. The tolerance depends on the size: a 0.5-mL ...
A dropping funnel or addition funnel is a type of laboratory glassware used to transfer liquids. They are fitted with a stopcock which allows the flow to be controlled. Dropping funnels are useful for adding reagents slowly, i.e. drop-wise. This is desirable when the quick addition of the reagent results in side reactions, or if the reaction is ...
for use in oral examination Transfusion kit: to transfuse blood and blood products Tuning fork: to test for deafness and to categorize it Ventilator: to assist or carry out the mechanical act of inspiration and expiration so the non-respiring patient can do so; a common component of "life support" Wartenberg wheel: for neurological use Watch ...
A reagent bottle is a type of laboratory glassware. The term " reagent " refers to a substance that is part of a chemical reaction (or an ingredient of which), and "media" is the plural form of " medium " which refers to the liquid or gas which a reaction happens within, or is a processing chemical tool such as (for example) a flux .
