Silica Gel Products
Silica gel is used in museums throughout the world to stabilize relative humidity (RH) in sealed exhibition cases and storage units.
Innovative research done by Steven Weintraub, founder of APS, resulted in the development of a new category of high-performance silica gels for museums that significantly increases buffering efficiency in the mid-RH range. RHAPID GEL was developed based on this research.
There are two types of silica gel used for museum applications:
​High-Performance Silica Gel (RHAPID GEL):
Excellent performance throughout the
0-65%RH range
Regular Density Silica Gel (ARTEN GEL):
Good performance at RH levels below 35-40%,
showing a rapid fall-off in performance above 45%RH
​Rhapid Gel and Arten Gel are calibrated and quality tested to be within 1-2% of the designated RH,
providing the most cost-effective high performing silica gel available.

Select Silica Gel Quantity Recommendation for information on determining the amount of silica gel quantity required
Note: APS offered Arten gel as a less expensive option for the lower RH range. Due to the increase in cost of all classes of silica gel, Arten Gel will be phased out. However, there is limited inventory of 30% RH Arten Gel available. When the inventory is depleted, 30% RH Rhapid Gel will be available.
