一、简介:

农药冻融稳定性试验箱依据NYT 2989-2016 农药登记产品规格制定规范设计制造。用于微囊液体制剂的冻融稳定性试验,压缩机、加热部分、电源控制部分均采用进口件,高质量、高性能。满载运转时冻融箱内各点温度极差不超过1℃。自动控制,数据曲线实时动态显示、试验数据自动存储,具有试验意外终止自动恢复功能。

微囊液体制剂等应进行冻融稳定性试验。试验目的是确保成囊制剂在温度变化时囊的完整性,以确保有效成分完整的释放。结冻和融化稳定性试验条件为在(-10±2)℃和(20±2)℃之间做4个循环,每个循环为结冻18h融化6h。微囊液体制剂主要有微囊悬浮剂(CS)、微囊悬浮-水乳剂(ZW)、微囊悬浮-悬浮剂(ZC)、微囊悬浮-悬乳剂(ZE)等剂型。

1.微囊悬浮剂(CS)及微囊悬浮-悬浮剂(ZC)冻融稳定性合格要求为:储后游离有效成分含量、酸碱度或pH范围、湿筛试验、悬浮率、自发分散性、倾倒性等应符合产品规格要求;

2.微囊悬浮-水乳剂(ZW)及微囊悬浮-悬乳剂(ZE)冻融稳定性合格要求为:储后游离有效成分含量、酸碱度或pH范围、湿筛试验、分散稳定性、倾倒性等应符合产品规格要求。

1. Introduction

The pesticide freeze-thaw stability test chamber is designed and manufactured in accordance with NYT 2989-2016 pesticide registration product specifications. It is used for freeze-thaw stability test of microcapsule liquid preparations. The compressor, heating part and power control part are all imported parts with high quality and high performance. The temperature difference of each point in the freezing and thawing box does not exceed 1℃ when operating at full load. Automatic control, real-time dynamic display of data curve, automatic storage of test data, and automatic recovery function for unexpected termination of test.

Freeze-thaw stability tests should be carried out for microencapsulated liquid preparations. The purpose of the test is to ensure the integrity of the capsule when the temperature changes in the encapsulated formulation, so as to ensure the complete release of the active ingredients. The freezing and thawing stability test conditions are 4 cycles between (-10±2)℃ and (20±2)℃, and each cycle is freezing for 18h and thawing for 6h. Microcapsule liquid preparations mainly include microcapsule suspension (CS), microcapsule suspension-water emulsion (ZW), microcapsule suspension-suspension (ZC), microcapsule suspension-suspension emulsion (ZE) and other dosage forms.

1. Qualified requirements for freeze-thaw stability of microcapsule suspension (CS) and microcapsule suspension-suspension (ZC) are: free active ingredient content after storage, pH or pH range, wet sieve test, suspension rate, spontaneous dispersion, Pourability, etc. should meet product specifications;

2. Qualified requirements for freeze-thaw stability of microcapsule suspension-water emulsion (ZW) and microcapsule suspension-suspoemulsion (ZE) are: free active ingredient content after storage, pH or pH range, wet sieve test, dispersion stability, dumping The performance should meet the product specification requirements.
