A few weeks before the anticipated sowing date, prepare the soil to suit the plants that are to be sown. Do not work the soil If it is too wet—this will destroy the soil structure and give poor germination and growth rates. If mud sticks to your boots, abandon the work until the soil is drier. 

All reagents must be properly labeled and dated as to content, date prepared or received, when placed in service, expiration date, and storage requirements. Routine monitoring of buffer pH is documented. 

Vortex vial intermittently for not less than 20 minutes. Water should come in contact with all internal surfaces, including the stopper during reconstitution. Reconstituted stock can be stored for 14 days at 2 to 8°C. Never freeze stock solution. Label stock with initials and date prepared. Vortex refrigerated reconstituted stocks 5 minutes before use. 

To prepare a 0.1 M glucose solution, weigh 18.02 g of glucose and transfer to a 1-liter volumetric flask. Add about 700-800 mL of purified water and swirl to dissolve. Then add water so that the bottom of the meniscus is at the etched line on the flask. Stopper and mix well. The flask must be labeled with solution contents (0.1 M glucose), date prepared, and name of preparer. 

Another part of input control is the proper labeling of reagents and materials. Proper identification should include the name, lot number (particular manufacturing batch), concentration, date received, date prepared, date opened, date of expiration, and recommended storage Conditions. In practice, such information is provided by manufacturers via a human-readable bar code. ...

All reagents must be properly labeled and dated as to content and quality (i.e., titer, concentration), date prepared or received, when placed in service, expiration date, and storage requirements. If necessary, this information may be recorded on a log as long as reagent containers are identified so as to be traceable to the appropriate data in the log. Reagents must be stored as recommended by the manufacturer. If ambient temperature is indicated, there must be documentation that the defined temperature range is maintained, and corrective action is taken when tolerance limits are exceeded. The laboratory must routinely monitor the pH of buffers.
