As one professional manufacture for Laboratory and medical plastic consumables, Runlab produces and supplies a wide range of products.
No one material can meet all experimental requirements. Whether glass or plastic is used depends on the application as well as the design, the specific properties of the material to be considered and, cost.
Runlab plastic raw materials:
What is the difference between the plastic raw materials? Is it acid and alkali resistant? Whether it can be autoclaved, here is an introduction:
Polypropylene has a structure similar to polyethylene (PE), but with a methyl group on every two carbon atoms in the chain. Its main advantage over PE is that it can be autoclaved. PP has good mechanical properties and chemical resistance and is the best among polyolefins in terms of resistance to cracking in stress, but is more susceptible to strong oxidizing agents than PE. In addition, PP is very brittle at 0℃, and it is easy to crack or break when dropped from high places.
As plastic raw material, Po;ypropylene is widely used for Runlab products. For example, Centrifuge tubes; Specimen containers; Cryovials; Storage boxes; Autoclave bags
Good rigidity and non-toxic, excellent dimensional stability, good chemical resistance to aqueous solutions, but poor resistance to solvents.
Transparent, hard, and generally used in the manufacture of disposable laboratory products. Products made with PS are brittle at room temperature and are prone to cracking or shattering when dropped.
As plastic raw material, Polystyrene is also widely used for Runlab products. For example, Serological pipettes; Specimen containers; Petri dish
It is a perfect straight-chain high molecular weight hydrocarbon made by ethylene polymerization.
Like other polyolefins, polyethylene is a chemically inert material. However, prolonged exposure to strong oxidizing agents will cause it to oxidize and become brittle.
It does not dissolve in any solvent at room temperature, and corrosive solvents will soften or swell the material, but these effects are generally reversible.
Polyethylene is widely used for Runlab products: Transfer pipettes (Pasteur pipettes); Tube stoppers
In addition to the above, there are many other materials, so I won't introduce them all here. When choosing supplies, whether to use the glass or plastic, according to the actual situation to judge it!
