Preparation equipment

All portable equipment and tools used in a sterile area must be thoroughly pre-washed with proper cleaning agents, final rinsed with WFI, and wrapped if required. These items are usually passed into the sterile area through a double door autoclave. Elimination of all particulate matter from any object entering the sterile area should be a major design consideration. 

All product-contact equipment, especially large mixers, should be electropolished. When stability is a concern, product should be cooled as soon as possible after leaving the cyclone separator. 

Materials that cannot be sterilized should be transferred into the sterile area through an isolated area in which an outer wrapping is removed. The object is then wiped down with a sanitizing agent such as isopropanol or hydrogen peroxide. 

Stationary equipment such as conveyors and filling equipment must be sanitized at some specified frequency. This can be accomplished by wiping down with a sanitizing agent or fogging the sterile area with formaldehyde. All product contact parts such as powder hoppers, filling wheels, and stopper bowls are removed from the sterile area, cleaned and sterilized as previously described. 

Freeze dryers are usually steam sterilized or sterilized using VPHP (vapor phase hydrogen peroxide). Trays used in a freeze dryer are usually cleaned and sterilized separately. 

Topics in this section include pressure testing to ensure that assembly meets the varying requirements of the process, special methods for thorough removal of traces of vapors, the importance of surface passivation in preventing corrosion, and the avoidance of accidental mixing of the wrong materials. 

Many different fluids are used in the pressure testing of piping and equipment. The most common are water, air, inert gases, and process fluids. Each option is discussed below. 

All piping components that had been removed should be reinstalled. All valves in the system, other than vents and drains, should be open. All rotating equipment should be removed from the system. 

All large tanks and vessels should be physically sconnected or blinded (all blinds should have visible tags). 

Water is often the most convenient testing medium, but several reasons may preclude its use. These include

Figure 5.7.3 The expected results and time frames when following a microcarrier or Nunc multiplate (MP) culture path. The microcarrier culture system requires one more extra day of equipment preparation compared with the MP pathway. One should also note that WI-38 will require an additional 24-h growth period in order to achieve comparable yields to that of MRC-5.

Having done the risk assessment, make sure that you wear personal protective equipment. Prepare all the crucibles, volumetric flasks, pipettes and beakers to be used, in advance, by soaking overnight in 0.5 M nitric acid. Then rinse three times with high purity deionised water and dry. 

Lyn Bates has written many technical papers and publications on aspects of bulk solids handling.

As we discuss there are various methods to produce carbon nanofibers or carbon nanotubes, for example, vapor growth [89], arc dischaige, laser ablation and chemical vapor deposition [28, 89]. However, these are very expensive processes owing to the low product yield and expensive equipment. Preparation carbon nanofiber by electrospinning of proper precursors is preferred because of its lower cost and more output [90]. 

Mix thoroughly two equal parts of coarse and fine sand. If using standard test sieves, combine 100 g of coarse sand with 100 g of fine sand. If using screen equipment, prepare a sample according to the size of the unit. Separate a sample to determine the moisture content using the moisture balance. 

Reagents and Equipment, Prepare a sample of 4-5 mg of recrystaUized trans-1,2-dibenzoylethylene in about 500 pL of CDQ3 in an NMR tube. Using a fine capillary, spot a silica gelTLC plate (see Experiment [6B]) with a sample of this solution. UseTLC to track the results of the NMR experiment.
