PC carboys, or polycarbonate carboys, are commonly used in homebrewing and laboratory settings for the storage and transportation of liquids. Whether or not they can be reused depends on several factors, including their condition, how they've been used, and proper cleaning and maintenance. Here are some considerations for reusing PC carboys:
1.Condition: Inspect the carboy for any signs of damage or wear. If the carboy is cracked, scratched, or has any visible damage, it should not be reused, as these defects can compromise its integrity and potentially lead to leaks or contamination.
2.Previous Contents: Consider what liquids were stored in the carboy previously. Some substances can leave behind residues or odors that are difficult to remove, making the carboy unsuitable for reuse. Chemicals that are particularly harsh or reactive may also degrade the polycarbonate material over time.
3.Cleaning: Proper cleaning is crucial for reusing PC carboys. Thoroughly clean the carboy with hot water and a mild detergent, followed by rinsing with water to remove any soap residues. Depending on what was stored in the carboy, you may need to use specialized cleaning agents or techniques to remove stubborn residues or stains.
4.Sanitization: After cleaning, it's essential to sanitize the carboy to eliminate any remaining microbes or contaminants. You can use a food-grade sanitizer or a solution of water and a no-rinse sanitizer specifically designed for homebrewing or laboratory use.
5.Storage: When not in use, store the carboy in a clean and dry environment. Ensure that it is protected from UV light, as prolonged exposure to sunlight can degrade polycarbonate over time.
6.Manufacturer's Recommendations: Check if the manufacturer of the PC carboy provides specific guidelines for reuse or a recommended number of reuse cycles. Following their recommendations can help ensure safety and longevity.
In summary, PC carboys can be reused if they are in good condition, have been properly cleaned and sanitized, and are compatible with the intended use. However, it's essential to inspect them carefully, consider their history, and follow appropriate cleaning and maintenance procedures to ensure their safe and effective reuse. If in doubt, it may be safer to replace a carboy rather than risking contamination or other issues.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
