In our aquarium test tube escapades, we found the unwelcome surprise of corrosive concoctions splashing onto our fingers and floors. To combat this, we sought leak-proof caps, prioritizing safety and cleanliness in our water monitoring endeavors.
While our Indian team diligently hand-calibrates and marks each tube, the occasional slight misalignment occurs. Coupled with the narrower necks designed for screw caps, we suggest utilizing a syringe for precise water dispensing into these tubes.
