Features:
Plastic is lightweight, chemically stable, will not rust, has good impact resistance, good transparency and abrasion resistance, good insulation, low thermal conductivity, general formability, good colorability, low processing cost, durability, waterproof, Lightweight.
PE MATERIAL
Low-density polyethylene is the lighter variety among polyethylene resins. Compared with high-density polyethylene, its crystallinity (5%~65%) and softening point (90~100℃) are lower; it has good softness, extensibility, transparency, cold resistance and processability; its chemical It has good stability and can resist acid, alkali and salt aqueous solutions; it has good electrical insulation and breathability; it has low water absorption; it is easy to burn. It is soft in nature, has good extensibility, electrical insulation, chemical stability, processing properties and low temperature resistance (can withstand -70℃).
Instructions:
1. When using a plastic dropper, pinch the top with your fingers to drive out the air in the dropper, then insert the dropper into the reagent bottle, release your fingers, and the reagent will be inhaled.
2. When adding liquid dropwise, place it suspended above the beaker and do not touch the wall of the beaker to avoid contaminating the dropper or causing contamination of the reagents.
3. Do not place the dropper on the test bench or other places to avoid contamination of the dropper.
4. Used droppers should be rinsed immediately with clean water for reuse.
5. It is strictly forbidden to use an uncleaned dropper to absorb other reagents (do not rinse the dropper on the dropper bottle with water).
