SAS 4 Flashcards
Traditionally in wet GRANULATION these equipment are used
Sigma blade, durable planetary mixer, and tumble blenders with high-speed blades
In DRYING these equipment are used
Hot air oven
Fluidized bed-dryer (substitute)
This is the ultimate test of a tablet formulation and granulation process.
Compression
Equipment used IN CAPSULE FILLING operations involve one of the two types of filling system.
Zanasi, MarTelli
HoFLIiger and karg
Equipment used in mixing Semi-solid
Colloid mill with fixed stator plate and high-speed rotating rotor plate
T or F: Transfer pumps for semi-solid products MUST BE ABLE TO MOVE VISCIOS MATERIAL WITHOUT APPLYING EXCESSIVE SHEAR AND INCORPORATION OF AIR.
T
What is the pump called for mixing semi-solid?
Positive displacement pumps
Provide 3 advantages of glass
impermeable
economical
chemically inert
Provide 3 disadvantages of glass
Fragile
Heavy
Bulky
What are the 4 principal components of glass?
Sand, Soda ash, Limestone, Cullet
Give the components or use of the following components of a glass.
Sand, Soda ash, limestone, cullet, Boron OXIDE, Aluminum oxide, lead
Sand - mainly silica
Soda ash - sodium carbonate
limestone - calcium carbonate
cullet - a broken glass that is used as a fusion agent
lead - used for clarity and brilliance
aluminum oxide - for glass durability and resistance to chemical reactions
boron - used to help melting process
What are the 4 basic processes in production of glass?
Pressing
Blowing
Drawing
Casting
In 4 basic processes in the production of glass:
- Uses COMPRESSED AIR to molten glass in the cavity of a metal mold.
- MOST COMMERCIAL BOTTLES ARE PRODUCED BY THIS METHOD.
Blowing
In 4 basic processes in the production of glass:
- Molten glass is pulled through dies or rollers that shape the soft glass.
- ITEMS THAT ARE UNIFORM IN DIAMETER ARE PRODUCED BY THIS METHOD.
Drawing
In 4 basic processes in the production of glass:
- Mechanical force is used to press the molten glass against the mold
Pressing
In 4 basic processes in the production of glass:
- Uses gravity or centrifugal force to cause molten glass to form in the cavity of the mold.
Casting
What are the 4 types of glass?
T1: BorosiLicate glass
T2: Treated Soda-lime glass
T3: Regular Soda-lime glass
T4: General purpose Soda-lime glass
In types of glass (T2): the dealkalanizing process is called…
Sulfur treatment
Give 3 advantages of plastic containers?
Light weight
readily available
Versatile
Give 3 disadvantage of plastic containers?
Permeable
Not environmentally friendly
Chemical reactions
Sorption
Provide the 7 types of plastics?
Polyethylene
Polypropylene
Polycarbonate
Polyvinyl chloride
Polystyrene
Polyethylene terepHthalate
Polyamide
Types of plastic: Has good barrier in moisture but poor in gasses.
Polyethylene
- unaffected by strong acid and alkali
Types of plastic: suitable for boilable packages and for sterilizable products
Polypropylene
- unaffected by strong alkali, strong acid, and most organic materials
- Except hot aromatic oil and halogenated solvents
Types of plastic:
- fairly good oxygen barrier and have greater stiffness.
- Clear rigid polyvinyl chloride bottles overcome some of the deficiencies of polyethylene
Polyvinyl chloride
Types of plastic:
- CAN BE AUTOCLAVED
Polyamine
Types of plastic:
- can be sterilized repeatedly
- has been considered a possible replacement for glass vials and syringes
Polycarbonate
PET meaning
Polyethylene Terephthalate
