for example:
1.8ml glass cartridges:
1. The raw material is COE 5.0 neutral borosilicate glass.
2. The following is the technical datas for the 1.8ml glass cartridges.
Glass body outside diameter: 8.65mm; Whole length: 63mm;
Mouth outside diameter: 7.15mm; Mouth inside diameter: 3.15mm
3. Packaging: 615 PCS in one inner PP tray box, and many tray boxes can be put into one carton box. As customers' requirement.
4. There are some import notes for using, please read it:
A. One complete set of glass cartridge contains: glass barrel, rubber plunger, and the Aluminum cap with seal inside. They are separated packaged, and all are sterilized.
If you donot need to buy rubber plunger or aluminum cap, please tell me.
B. Before filling medicine, cleaning, silication and drying sterilization are required, this process is carried out in a pharmaceutical or medical device factory.
Please pay attention to this.
