PROBLEMS
Normal Plastic Syringes eg Terumo, most “pharma” syringes
Black Rubber tip Plunger seal
- push on fit is a trap for contaminants re re-use
built-in obsolescense by “pharma industry”
- the black seal is coated with a film of silicone oil
- with oily sample this dissolves . . . the tip “dries out “ and plunger wears and sticks . . . thus more of . . . throw-a-way design
