ACT 1

• This equipment allows for magnification and visualization of cells and cellular components that cannot be seen with the naked eye.

  Microscope
• It is a thin, flat, rectangular piece of glass that is used as a platform for microscopic specimen observation

  glass slide
• It is a small square of glass that covers the specimen placed on the microscope slide. 

  cover slip
• This is a shallow cylindrical container with fitted lid that is designed specifically for microbiology or cell culture use.

  petri dish
• This is a laboratory glass container characterized by its narrow cylindrical mouth and cone-shaped main body and is often used for stirring or heating solutions.

  erlenmeyer flask
• These are slender containers that hold small amounts of liquid and are used in various scientific experiments

  test tube
• These are used to handle and culture all kinds of living organisms (e.g. bacteria, fungi, protists, etc.)

  culture tube
• This is used to transfer small quantities of liquids.

  dropper
• This is a tool usually made of platinum or nichrome wire in which the tip forms a small loop with a diameter of about 5 mm, and is used to smear, streak, or take an inoculum from, a culture of microorganisms, usually in liquid media

  inoculating loop
• This is a tool used to retrieve solid or dense media from a culture of microorganisms.

  inoculating needle
• It is wide-mouthed glass jar with vertical grooved interior walls. It is used to store and/or hold microscopic slides vertically during staining procedures.

  coplin jar

  
• This is usually made of stainless steel and holds multiple microscopic slides simultaneously during the staining process.


  staining rack

  
• This is a laboratory apparatus that consists of a flat base with a vertically extending straight tube, called a barrel or chimney. It produces a safe, smokeless, hot, non-luminous flame that can be used for various scientific experiments.

  bunsen burner
• This equipment is characterized as a cylindrical metal vessel having double walls (except at the opening) and can withstand high pressure with superheated steam. It is used for sterilizing media, solid and liquid heat-stable liquids, heat resistant instruments; glassware, etc. However, it is not used for volatile oils, powders, heat-sensitive fluids such as serum.

  autoclave

  
• This equipment is characterized by its three walls, with the outer wall covered with thick asbestos, and two air spaces. The instrument is usually used for drying autoclaved materials, powders, waxes, metal equipment at temperature range of 160-180 °C for 1 to 1⁄2 hr.

  hot air sterilizer

  
• It is an apparatus with a chamber used to provide controlled environmental conditions (such conditions as temperature and humidity) usually for the cultivation of microorganisms.

  incubator

  
• This is a carefully enclosed bench that is designed to prevent contamination of biological samples or any particle-sensitive device. The cabinet is usually made of stainless steel with no gaps or joints where spores might collect.

  laminar air flow

  
• It is a highly sensitive lab instrument that contains a draft shield or weighing chamber to prevent the very small samples from being affected by air currents. It is designed to accurately measure mass with readability at a range between 0.1mg - 0.01mg.

  analytical balance
• This is a microbiology instrument used for counting the population of bacteria, based on the principle of turbidity determination.

  spectrophotometer

  
• This equipment may be used for sedimentation of cells and viruses or to isolate macromolecules such as DNA by spinning at high speed and using g-force to separate particulates in suspension according to their density.
