How long a period are Hands-On-Labs, Inc. LabPaqs normally used?
LabPaqs contain the number of traditional experiments that normally accompany a one-semester college course or a one-year in high school course. Each LabPaq is hand assembled and does contain some materials that have a limited shelf live. They are manufactured based on the timing provided by your educational institution and instructor and shipped when ordered by students taking the class to ensure that all materials are usable. Q: The fluid in my spirit thermometer has separated. How do I re-unite the separated fluid in the measurement column? Due to safety considerations, a spirit, rather than mercury, thermometer is included with LabPaqs. Occasionally, the fluid in spirit thermometers will separate during storage and/or shipping, but this is a correctable problem. The two methods described below can be used. Remember to wear hand and eye protection when you perform either of these correction procedures.
