19
Q

Type of mechanical pipette which relies on piston for suction creation to draw the sample into a disposable tip.

A

Air Displacement Pipette

20
Q

T/F:

The piston of an air displacement pipette does not come in contact with the liquid

21
Q

Type of mechanical pipette which operates by moving the piston in the pipette tip or barrel, much like a hypodermic syringe. It also does not require a different tip for each use.

A

Positive Displacement Pipette

22
Q

A mechanical pipette that obtains liquid from a common reservoir and dispenses it repeatedly. It also combines sample and dispensing functions.

A

Dilutor/Dispenser Pipette

23
Q

most commonly used type of glassware used for heating and sterilization purposes

A

Borosilicate glass (pyrex and kimax)

24
Q

pyrex strain point

25
Q

type of glassware made up of soda-lime glass and a mixture of calcium, silicon, and sodium oxides

A

Flint glass

26
Q

type of glassware that has poor resistance to high temperatures; easy to melt and is used to make disposable glasswares

A

flint glass

27
Q

type of glassware utilized for high thermal, drastic heat shock and extreme chemical treatment with acids (except hydrofluoric) and dilute alkali

A

Vycor (corning)

28
Q

type of glassware characterized by a high degree of thermal resistance, has low alkali content, and is free from the magnesium lime-zinc group of elements, heavy metals, arsenic, and antimony

A

Borosilicate glass (pyrex and kimax)

29
Q

type of glassware that has high resistance to alkali and has thermal resistance less as compared to borosilicate glass

A

Boron-free glassware/soft glass

30
Q

type of glassware that is a special alumina-silicate glass that has been strengthened chemically than thermally and is six times stronger than borosilicate

A

Corex (corning)

31
Q

term which refers to a type of testing where all samples are loaded at the same time with a single test conducted on each sample

A

batch testing

32
Q

type of testing where more than one test is analyzed concurrently on a given clinical specimen

A

parallel testing

33
Q

type of test where any test can be performed on any sample in any sequence

A

Random access testing

34
Q

type of test where multiple tests are analyzed one after another on a given specimen

A

sequential testing

35
Q

a system other than manufacturer’s reagents can be utilized for measurement

A

Open reagent system

36
Q

a system where the operator can only use the manufacturer’s reagents

A

Closed reagent system

37
Q

provides point-to-point delivery of specimens to the laboratory and offers several advantages over specimen transport by humans

A

Pneumatic tube delivery system
