WiseMini® Molecular Sieve Desiccant Strip

4A Molecular Sieve Continuous Desiccant

WiseMini® Molecular Sieve Strip Desiccant is a type of desiccant based off of our WiseMini® Molecular Sieve Sachet and allows customers to deliver our desiccants into their packaging through automated means. It works seamlessly with the automatic cutting and dispensing machine thus greatly improving safety and efficiency. WiseMini® Molecular Sieve Strip Desiccant is an FDA approved desiccant. Molecular sieve desiccants have stable cellular structure and a uniform pore diameter. In addition, it has a strong mechanical strength and moisture absorption capacity at both high and low temperatures

1. Why use Ultrasonic sealing?
Ultrasonic sealing is an environmentally friendly process not using any sort of adhesive/glue to close each desiccant. It is an overall stronger seal as well.

2. What type of ink do you use?
Our WiseMini® Molecular Sieve Strip Desiccants all utilize FDA approved water-based ink and are non-toxic. Additionally, no ink is printed on the desiccant bag edges leading to higher strength edges.

3. Why use molecular sieve?
4A Molecular Sieve is a very sensitive adsorbent where even the smallest bit of humidity can be absorbed and detected successfully.

4. How many sizes do you have in total?
There are 5 different standardized sizes of WiseMini® Molecular Sieve Strip Desiccant: 0.25g, 0.5g, 1g, 2g, and 3g.

5. How do I automatically dispense WiseMini® Molecular Sieve Strip Desiccants?
You can utilize any of Wisesorbent’s Cutting and Dispensing Machines along with any other standard Cutting and Dispensing Machine for Desiccant Strips.

6. Why use Uncoated Tyvek?
Uncoated Tyvek is used as our packaging material due to it being breathable but at the same time having a high strength. This combination allows for our sachets to have a high adsorption rate while also being very safe.

7. What type of products should use WiseMini® Molecular Sieve Strip Desiccant?
WiseMini® Molecular sieve Desiccant strips are great for diagnostic reagents, testing materials and medical devices. Anything that is ultra-sensitive to being in contact with even the slightest bit of moisture is recommended to use Molecular sieve due to its capability to absorb moisture at the lowest percentages.
