Principles of Medical Laboratory Science Practice 2 (1)

What is the primary use of glassware in the laboratory?

Glassware is mainly used for measurement, containment, or storage.

What are the advantages of plasticware over glassware?

Plasticware is less expensive and more durable.

What type of glass is typically used for thermal resistance?

Borosilicate glass is usually used for thermal resistance.

What is the brand name of borosilicate glass commonly used in laboratories?

Pyrex is a widely recognized brand of borosilicate glass.

What type of glass is used to store substances sensitive to light?

Low-actinic glass, which is amber-colored, is used for this purpose.

What are volumetric flasks used for?

Volumetric flasks are used to prepare a specific volume of reagent or laboratory solution.

What does TC stand for in terms of glassware calibration?

TC stands for 'To Contain,' indicating the flask is calibrated to contain a specific volume.

What type of pipettes are usually calibrated to deliver a fixed volume of liquid?

Volumetric pipettes are calibrated to deliver a fixed volume.

What is a centrifuge used for in a laboratory?

A centrifuge uses centrifugal force to separate particles in suspension.

What is the function of a microhematocrit centrifuge?

It is used for spinning capillary tubes of blood to obtain the hematocrit value.

What type of balance is often used for precision in weighing chemicals?

An analytical balance is used for very accurate measurement of chemicals.

What is the primary purpose of an incubator in a laboratory?

An incubator is used to maintain a constant temperature for culturing bacteria or other organisms.

What safety measure should be taken when using a centrifuge?

Always balance the tubes placed in the centrifuge.

What kind of glass is most commonly used for making inexpensive, disposable laboratory items?

Flint glass is commonly used for disposable glassware.

What is the maximum capacity of a refrigerated centrifuge?

It can maintain an internal temperature ranging from -15°C to -25°C.

What is the purpose of a vortex mixer?

It is used for mixing contents in a single test tube to create a uniform solution.

What device do you use to monitor the temperature of temperature-controlled units?

Thermometers and temperature-sensing devices are used for monitoring.

What is a spectrophotometer used for in a laboratory?

It quantifies a substance in the blood by measuring light intensity relative to wavelength.
