Disposables for electronic and medical applications

Disposables for electronic and medical applications

Many adhesive chemistries require disposable products suited to their properties and caution should be exercised in selecting the right syringe and needle (tip) system to deliver the material. Intertronics has in stock an extensive range of tips, needles and syringes from the I&J Fisnar brand which are ideally suited to these situations.

 

Guidelines for consumable selection include being aware that UV curing products will vary in sensitivity and it is therefore possible to use a less opaque barrel, so that fluid levels can be observed; however it is important to check the specification with the material supplier. The tip should always be manufactured using a high grade of stainless steel.

 

Similarly, cyanoacrylate adhesive requires polyethylene and/or PTFE disposable parts. The polymerisation of cyanoacrylate is a reaction which occurs when the adhesive comes into contact with humidity or metal ions present on the substrates. PTFE inserts can be provided within a stainless steel needle to avoid contact.
