试剂检测套件的储存和保质期:如何防止你的试剂失效

试剂不是永远有效的。不当储存可能导致错误结果。学习如何正确储存你的检测套件以获得最准确的结果。

试剂的敌人

  • :将试剂储存在阴凉处(冰箱是理想的,4-8°C)
  • :紫外线降解试剂——使用琥珀色瓶子
  • 空气:每次使用后立即盖紧盖子
  • 时间:大多数试剂保质期为12-18个月

如何判断试剂已过期

  • 颜色变深或变色——新鲜试剂应该是清澈或淡色的
  • 已知样品的不一致结果
  • 开瓶超过18个月

最佳实践

  • 在瓶子上标记打开日期
  • 储存在原装琥珀色瓶中
  • 不要将试剂转移到其他容器中
  • 在室温下使用,使用后立即放回冰箱
