Details & Notes

Easily sealable lever band type

The [CTL] series is a stainless steel container that can be easily sealed with the attached lever band. The type of lever band or lid varies depending on the size.

See product images and drawings for detailed specifications.

For 24 ~ 47 H size, containers can be stacked (stacking)!

CTL sizes -24 to 47 H can be stacked empty with lid and band closed. Cannot stack CTL -565 size or larger.

Easy-to-clean corner R bottom

Round stainless container without corners.
R (Radius/Round) is attached to the rising part of the bottom to prevent the contents from entering and to make it easy to remove dirt.
Can be used hygienically as it has excellent washability inside the container that directly touches the contents.

Packing attached differs depending on the size.

CTL sizes -24 to 47 H come with L type, and sizes over 565 come with B type as standard.

L-type packing is a packing to be set on the CTL lid.
CTL -24 ~ 47 H size standard accessory.

B type packing is a packing to be attached to a sealing lid.
CTL -565 ~ 100 H size standard accessory.

Mounting method of L-Type packing

Lid specifications vary depending on size.

CTL lids are included for sizes -24 to 47 H, and sealed lids are included for sizes 565 and above.

CTL lid is a lid exclusively for lever band type sealed container.
CTL -24 ~ 47 H size standard accessory.

Sealing lid is a lid for large sealed container.
CTL -565 ~ 100 H size standard accessory.


Dedicated truck to support transportation of stainless steel containers (Sold separately)

For moving heavy containers or large containers with contents, it is recommended to use the special cart “Container carrying truck” for stainless steel containers made by Nitto Kinzoku Kogyo.
Available in sizes that match the container size, the specifications can be selected according to the customer’s preferences and usage environment.

You can also buy only the “packing” “container body”.

Please let us know your desired specifications at the time of the estimate. We also accept orders for consumable items such as lids only and packing only.
*We do not sell only handles and clips.

Available to products made of SUS316L material!

The standard material for Nitto Kinzoku is SUS304.
SUS316L is a material with higher corrosion resistance than SUS304.
It contains an ingredient called “molybdenum”, which is not contained in SUS304.
This molybdenum makes the passive film thicker and improves the corrosion resistance.

SUS316L is a low-carbon type stainless steel with a low carbon content, and is resistant to corrosion (intergranular corrosion) in the welding area where parts are connected to each other.
SUS316L is generally recognized as a high-grade model of stainless steel material.

It is a material that is commonly used in production sites in the pharmaceutical industry.
If you are concerned about rust and corrosion resistance, we recommend you to select SUS316L.
For more details, please contact us.



Can I change the material of the container?
Yes. There is SUS 316 L.
Is there any material other than silicon for the packing?
There are FKM (Fluorine Rubber), EPDM (ethylene-propylene rubber), NBR (nitrile rubber), and CR (chloroprene rubber).
Can I put pressure on this container?
You can not pressure. Please use the pressurized vessel.
Can the packing be removed?
You can remove it.
Do you have 4L or 7L size?
The 4L and 7L sizes are not in the lineup, but the height of the 10 L (Inner Diameter ø 240 mm) container can be lowered to reduce the capacity by special order.
