Description
Flat Square HDPE Reagent Bottle
Flat Square HDPE Reagent Bottles are integrally molded from high-density polyethylene and fitted with sealed screw caps, tailor-made for biochemical testing and IVD reagent filling. In-stock options include light-shield yellow, light-proof brown and transparent versions; opaque bottle bodies block ultraviolet rays to prevent light-sensitive reagents from degradation.
HDPE is a highly crystalline, non-polar thermoplastic resin presented as non-toxic, odorless white pellets with a melting point of roughly 130℃ and relative density ranging from 0.941 to 0.960. The material features reliable heat and low-temperature resistance, stable chemical performance, balanced rigidity and toughness, plus outstanding mechanical strength.

Application
Guide Medlab HDPE flat square reagent bottles are tailor-made for biochemistry analyzers, extensively used in clinical diagnostic labs, chemical labs, cosmetic compounding, pigment storage and industrial reagent packaging.
● For storage and aliquoting of biochemical assay reagents, diagnostic fluids, colorants, calibration standard solutions, liquid chemical raw materials and lab buffer liquids.
● Light-shield amber and yellow HDPE blocks UV radiation to stop light-sensitive contents from decomposition, suitable for short-period machine testing and long-term reagent preservation.
● Resistant to most water-based reagents as well as weak acids and alkalis; compact flat square structure maximizes space efficiency for lab racks and analytical instrument matching.
● Trusted by hospital clinical laboratories, IVD reagent factories, environmental testing organizations, cosmetic R&D labs, QC inspection centers and biochemistry analyzer supporting suppliers.
Quality Control

Packing, Storage and Transportation
●Storage
Keep goods in dry, cool and shaded indoor storage. Amber and yellow HDPE bottles deliver light-blocking performance to prevent light-induced deterioration of contained reagents; avoid direct sunlight and humid surroundings.
●Transportation
Small sample and small-batch orders can be shipped via couriers like FedEx, DHL and EMS. Sea freight is recommended for large bulk shipments to cut logistics costs.
●Packing
Custom packaging options are offered, including bulk plastic bag packing and standard export carton packing.
