1

The predominant practice of celcius on centigrade uses

celcius, farenheit, kelvin

2

reactions that are temperature dependent use some type of:

heating/cooling cell, heating /cooling block, water/icebath

3

kinds of thermometers

liquid-in-glass thermometers, electronic thermometer, digital thermometer

4

another SRM, has a known melting point and can also be used for thermometer verification

Gallium

5

has increased and is now routinely incorporated in many devices

electronic thermometer

6

the advantage of thermistor over the more traditional liquid-in-glass thermometers are?

size and millisecond response time

7

Glasswares used in clinical laboratory usually fall into one of the following categories

Kimax/Pyrex (borosilicate)
Corex (aluminosilicate)
high silica
vycor (acid and alkali resistant)
low actinic (amber colored)
flint (soda lime)

8

the major types of resins frequently used in the clinical chemistry laboratory

polystyrene, polyethylene, polypropylene, tygon, teflon, polycarbonate, and polyvinyl chloride

9

is calibrated to hold one exact volume of liquid

volumetric flask

10

are designed to hold different volumes rather than one exact amount

erlenmeyer flask and griffins beakers

11

are glass or plastic utensils used to transfer liquids, they may be reusable or disposable

Pipets

12

Design

to contain
to deliver

13

drainage characteristics

blowout and self-draining

14

measuring or graduated

serologic
mohr
bacteriologic
ball, kolmer or kahn
micropipet

15

transfer

volumetric
ostwald-folin
pasteur pipets
automatic macropipets or micopipets

16

has a continuous etched ring or two small, close, continuous rings located near top of the pipet

blowout pipet

17

user allows the contents of the pipet to drain by gravity

self-draining

18

does not have graduations on the tip

mohr pipet

19

has graduation marks to the tip and is generally a blowout pipet

serologic pipet

20

these pipets are designed to dispense volume without further subdivisions

transfer pipets

21

bulblike enlargement in the pipet stem easily distinguishes

ostwald-folin and volumetric subgroups

22

is design to dispense or transfer aqueous solutions and is always self draining

volumetric pipets

23

do not have calibration marks and are used to transfer solutions or biologic fluids without consideration of a specific volume

pasteur pipets

24

the most routinely used pipet in todays clinical chemistry laboratory

automatic pipet

25

a pipet with a pipetting capability of less than 1mL is considered a

micropipet

26

a pipet that dispenses greater than 1mL is called

macropipet

27

relies on a piston for creating suction to draw the sample into a disposable tip that must be changed after each use

air-displacement pipet

28

automatic pipets that can be categorized

air displacement, positive-displacement and dispensers

29

operates by moving the piston in the pipet tip or barrel, much like a hypodermic syringe and the piston does not come in contact with the liquid

positive-displacement pipet

30

are automatic pipets that obtain the liquid from a common reservoir and dispense

dispensers
