Installing Omni Tips; Chemical Resistance - Omni PCR-258 User Manual

SECTION 5 —OMNI TIP™ PLASTIC PROBES

5.2 INSTALLING OMNI TIPS™

See Section 3.3
NOTE:
Omni Tip plastic probes should not be immersed above the
cone leading to the adapter during processing, since liquid may be
drawn up the shaft and contaminate the coupling.

5.3 CHEMICAL RESISTANCE

Omni Tips™ generator probes are made of polycarbonate and an
amorphous thermoplastic polythermide. The plastics used in Omni
Tips™ have good chemical resistance to weak acids, chlorides,
hypochlorides, and many other chemicals, allowing for reuse. However,
phenol or guanidine-based reagents, commonly used in PCR studies,
are not recommended for extended use with Omni Tips™. Exposure to
these chemicals shortens the life of Omni Tips™ and usually results in
disposal after each use. Therefore, reuse is not guaranteed in such
circumstances. If any cracking or brittleness is detected in an Omni
Tips™ generator probe, it is recommended that it be discarded. Due to
the many different chemicals and environments in which processing
takes place, it is the responsibility of the user to set sterilization
guidelines and protocols to optimize the life and performance of their
Omni Tips™ generator probes.
