Application
Guide Medlab Nalgene-style HDPE square bottles are high-performance lab reagent containers, widely applied in analytical chemistry labs, environmental sampling work, pharmaceutical development, industrial QC and life science research.
● Ideal for storing, sampling and dispensing aqueous solutions, diluted acids, alkalis, alcohols, aldehydes, esters and aliphatic hydrocarbons. Excellent chemical inertness avoids cross-contamination between the bottle and stored substances.
● Offers outstanding low-temperature impact resistance down to -100°C, paired with leak-tight screw caps. The flat square shape improves rack storage efficiency and stacking stability.
● Fit for on-site short-term sampling tests as well as long-term sealed storage of liquid specimens, standard solutions and liquid chemical raw materials.
● Commonly used by environmental monitoring labs, chemical manufacturers, clinical testing departments, life science research institutions and quality inspection centers.
Quality Control
Packing, Storage and Transportation
●Storage
Store bottles in a dry, cool and well-ventilated warehouse. Avoid direct sunlight and high-temperature environment. The opaque HDPE bottle body provides inherent light shielding to help stabilize light-sensitive contents.
●Transportation
Small sample orders can be shipped by couriers such as FedEx, DHL and EMS. Sea freight is recommended for large bulk orders to control logistics cost. Goods shall be protected against heavy extrusion, sharp impact and rain during transit.
●Packing
