Dual Element

Also known as Bi-Active Heat.  This option is used to seal thick materials or materials that require a high temperature to seal.
A standard sealing machine is equipped with a single sealing bar. A unit with the dual element option has two seal bars, this allows both sides of the film to be heated simultaneously. It also reduces the time it takes to seal a material, increasing production and output.
Typical applications for the Dual Element option include, tubes and flexible packaging used for products made with glycerin, oils or thick creams that can seep between the layers during the sealing process.

Dual Element Kill Switch Option

This option refers to a toggle switch that allows the user to turn the second heating bar on or off on a unit that already has the dual element option.
This option will convert the sealing unit from single element to dual element and back at the flip of a switch. This is extremely useful when sealing tubes of varying thickness, or when sealing different types of products on the same machine.

220 Volt Option

In the United States, 110 volts of power is standard. However, in places such as South America, Europe, Australia, and parts of Asia, the standard is 220 Volts of power. This option allows the user to operate the unit where 220 Volts of power are available.

5/8” Wide Element with 220 Volt Option

he 220 Volt unit comes with a ¼” wide heating element. This option allows the unit to have a 5/8” wide heating element. This is used for aesthetic purposes or for larger tubes that require wider seals. This option is only available for units that work with 220 Volts of power.

Bar Drilled Option for Water Cooling

This option refers to the holes that have been drilled through a second seal bar that allow cool water to flow through the bar. As the unit is used repeatedly, the heating elements tend to get hotter and, after a while, the user must pause to allow them to cool before resuming sealing. With a water cooled system, this wait time is dramatically reduced. Note: For this to work, you must also have a Digital Water Chiller. See below

Digital Water Chiller

This self-contained water cooling and circulating system allows the user to cool the heating elements by using cold water. This option can dramatically increase sealing production by reducing cool down time. Note: for this to work, you must have the Bar Drilled Option for Water Cooling described above.

Bar Drilled For Air Cooling

The seal bars have been drilled to allow for air cooling. While reducing wait time and increasing production, this option is not as effective as the water cooled system.

Additional Tube Racks (available only for the MSTSS760 Pneumatic Tube Sealer)

Custom cut tube racks made to the customer’s specifications. This allows the user to have multiple tube racks available for use. The use of multiple racks can speed up production time.

Heated coding Bar Option (available only for the MSTSS760 Pneumatic Tube Sealer)

This custom embossing attachment is made according to the customer specifications. This option allows the user to emboss a message in the seal of tubes. Available only for a single element machine, this option can be used for Part Numbers, Lot Numbers, Company Names, dates, or any other information necessary. You will need to purchase the number and letter sets separately. For additional information, please contact our sales department at
