Adjusting a Crimper

Required devices¶

No.	Parts name	Category	Required number
①	Hand crimper （Electronic crimper）	Hand crimper/Hand decapper (Electronic crimper/Electronic decapper)	1
②	Gloves (thick)		1
③	Hex wrench		1
④	Vial	Vials for HS-20 series	1
⑤	Vial cap	Vialcaps for HS-20 series	1

Procedures¶

Since a high-temperature cap will be exposed to a high temperature, the cap may leak if tightened in the same way as the pressure-release type.
A high-temperature cap must be sealed more tightly than the pressure-release type.
The crimper must be adjusted according to the type of vial cap (e.g. pressure-release cap, high-temperature cap).

Step 1¶

Before trying on samples, check the crimper operation first with an empty vial according to Crimping a Vial Cap .
If there is no problem found with the crimper operation, the following crimper adjustment steps can be omitted.

Step 2-1¶

When using a manual crimper such as the type shown below

If the crimp is too weak, use a hex wrench to adjust the crimper.
Turn the adjustment screw to the left as shown in the bottom image on the left.
If the crimp is too strong, use a hex wrench to adjust the crimper.
Turn the adjustment screw to the right.

When changing from the pressure-release vial cap to the high-temperature vial cap
Using a hex wrench, turn the crimper adjustment screw once to the left from the position for the pressurerelease vial cap.


	Do not turn the adjustment screw too far to the left. A vial cap or a vial may become damaged and will not seal once deformed.

Step 2-2¶

When using a manual crimper such as the type shown below

If the crimp is too weak, turn the orange adjustment knob in the + direction.
If the crimp is too strong, turn the orange adjustment knob in the - direction.


	Do not turn the adjustment knob too far in the + direction. A vial cap or a vial may become damaged and will not seal once deformed.

Step 2-3¶

When using an electronic crimper such as the type shown below

If the crimp is too weak, press the + button.
If you press the + button, the Status LED will light amber.
If the crimp is too strong, press the - button.
If you press the - button, the Status LED will light green.


	Do not press the + button too many times. A vial cap or a vial may become damaged and will not seal once deformed.
	Do not use an electronic crimper or decapper with a high-temperature vial cap as the vial may become damaged. Electronic crimper and decapper are only used with the pressure-release type vial cap.

Step 2-4¶

When using an electronic crimper such as the type shown below

If the crimp is too weak, press the ▽ button.
If you press the ▽ button, the percentage of the LCD panel rises.
If the crimp is too strong, press the △ button.
If you press the △ button, the percentage of the LCD panel decrease.


	Do not press the ▽ button too many times. A vial cap or a vial may become damaged and will not seal once deformed.
	Do not use an electronic crimper or decapper with a high-temperature vial cap as the vial may become damaged. Electronic crimpers and decappers are only used with the pressure-release type vial cap.

Step 3¶

Once a crimper and decapper are adjusted, sealing should be checked with an empty vial before trying on
samples according to Crimping a Vial Cap .
Repeat the adjustments until a proper sealing is obtained.
