How To Use A Manual Vial Crimper? 

Adjusting Crimpers for Use

1. Select 5 or so vials, caps, and seals for the purpose of setting the crimp.

2. Place the seal and cap on the vial and rest the crimper on top of the cap.

3. Squeeze the handles until the adjustment knob has seated against the top of the plastic case. This is the stop position, and the crimper cannot be tightened further.

4. Check the crimped vial for satisfactory form and tightness. If the cap spins easily, turn the adjustment know about ½ turn in the + direction. Try the new setting with a new vial and cap.

5. Crimping the same vial two times will not generally give the same results and sometimes will result in vial breakage. See the section on “Troubleshooting” for more information.

6. If the crimp is too severe, or the cap is too tight with deformed sides, try a lighter setting by pressing turning the adjustment knob in the – direction.

7. Special considerations for 20mm Headspace vials. It is common practice to use the “twist test” to check headspace vials for satisfactory crimps. In fact many sealing systems hold pressure perfectly well so long as the seal is well compressed.

Adjusting Decappers for Use

The adjustment is not very important when decapping. As shipped from the factory the decapper should remove a cap satisfactorily.

1. The 11mm decappers work by closing the jaws around the neck of the vial and stripping the cap off. For the 11mm decapper to work the glass vial must be strong enough to resist the force applied by the decapper. In the case of inferior or soft glass or if a vial is reused the lip of the vial may break during decapping. To adjust the 11mm decapper make sure that the stroke is long enough to remove the cap.

2. The 20mm decapper works by pinching the sides of the cap with the decapper jaws and pushing out the glass. The pinching action starts to pull the cap off, and the force of the decapper does the rest of the work. To adjust the 20mm decapper, just make sure that the stroke is long enough to remove the cap.

Maintenance and Cleaning

The crimping tool may not be immersed in water or solvent. The outside of the case may be cleaned with an ordinary detergent and wiped off with a damp rag. Avoid permitting metal parts of the crimping tool come into contact with corrosive material during use. If they do, try to wipe them clean with a suitable mild neutralizing solution. If metal fines accumulate around the inside of the jaws they can be wiped out with a cotton swap or small rag.

 

Electric Flip Off Caps Crimper / Decapper

An optimal crimp result is characterized by the following features:

1. The cap surface is flat and the cap sides fit tightly and firmly around the glass edges without any deformation of the aluminium surface.

2. The septa neither emerges out of the center hole of the cap nor is being sucked into the vial.

3. The cap cannot be turned by usage of single fingers without enormous expenditure of energy.
