STNY-108 Pesticide Freeze-Thaw Stability Tester High-Performance
Pharmaceutical Testing Instruments
STNY-108 pesticide freeze-thaw stability tester is designed and
manufactured according to the specifications of NYT 2989-2016
pesticide registration products. For the freeze-thaw stability test
of microencapsulated liquid formulations, imported components are
used for the compressor, heating section, and power control
section, ensuring high quality and performance. The temperature
difference at each point inside the freeze-thaw box during full
load operation shall not exceed 1 ℃. Automatic control, real-time
dynamic display of data curves, automatic storage of experimental
data, and automatic recovery function for unexpected termination of
experiments.
Microcapsule liquid formulations should undergo freeze-thaw
stability tests. The purpose of the experiment is to ensure the
integrity of the capsule when the temperature changes, in order to
ensure the complete release of the active ingredient. The
conditions for the freeze-thaw stability test are to perform 4
cycles between (-10 ± 2) ℃ and (20 ± 2) ℃, with each cycle lasting
18 hours of freezing and 6 hours of melting.
