What is Cuvette?
[[Image:Cuvette with penny.jpg|thumb|A plastic cuvette. A [[Cent (United States coin)|penny]] is included to compare size.]] A '''cuvette''' is a kind of [[laboratory glassware]], usually a small tube of circular or square cross shape, closed at one end and open at the other, made of [[plastic]], [[glass]], or optical grade [[quartz]] and made to hold samples for [[Spectroscopy|spectroscopic]] experiments. The best cuvettes are as clear as possible, without impurities that might affect a spectroscopic reading. Like a [[test tube]], a cuvette may be open to the air on top or have a glass or other material to close it. {{tech-stub}} {{LaboratoryEquipment}} [[Category:Laboratory equipment]]
