Intersurgical Spherasorb Soda Lime Absorbent

Spherasorb medical grade soda lime is formulated for clinical use. Spherasorb is available in two indicator color changes, pink to white and white to violet. Both products have a distinct color change which gives a clear indication of the product status. It is recommended that the color is used as an indication of exhaustion in conjunction with monitoring of Carbon Dioxide.

Spherasorb is designed specifically for medical use as a Carbon Dioxide absorbent. The absorption of Carbon Dioxide by soda lime results in an exothermic reaction. All soda lime brands will generate heat, especially if exposed to higher than normal expiratory levels of Carbon Dioxide.

Unique properties of Spherasorb

• Spherasorb is a unique soda lime developed specifically to address the potential problems of use within the medical environment.
• Spherasorb is made of 3-4mm spheres processed to minimise potential dusting. Its uniform shape allows consistent bed packing, resulting in a more even flow of anesthetic gases through the absorber.
• Spherasorb has independently proven benefits of reducing the risk of Carbon Monoxide generation and reaction with volatile anesthetics. Spherasorb is more difficult to dry out than other soda limes.
• Spherasorb has been independently shown to absorb more Carbon Dioxide than granulate soda limes.

Low dust

The unique manufacturing process used to produce Spherasorb ensures that the dust content of the product is significantly lower than other soda limes. In clinical use it will minimize resistance to flow of gases. It reduces the potentially harmful risk of dust contamination to the patient and the equipment.

Hardness

The unique formulation of Spherasorb means that when tested for hardness, in accordance with USP specifications, it is found to be significantly superior to other competitive brands.

This together with the regular shape, minimizes the amount of dust produced during transit allowing the product to reach you in perfect condition for use(3). Spherasorb will not break down if subjected to high humidity, and has a positive effect on the humidity in the system.

Anaesthetic Degradation

Spherasorb does not contain potassium Hydroxide or Barium Hydroxide and only a very low level of Sodium Hydroxide. Spherasorb also contains a low level of a specific Zeolite.

Independent tests have shown that Spherasorb has a unique formulation that presents less of a risk of the anesthetic degradation products, Carbon Monoxide and Compound A. Tests have also shown that Spherasorb is more difficult to dry out than any other soda lime brands(10). Since significant degradation occurs only when soda lime is dry, Spherasorb is an even safer product to use.

Spherasorb is a high quality medical soda lime manufactured from mixture of Calcium and Sodium Hydroxides and an inert hardening agent. It is supplied in the form of hard, porous regular rounded pellets which have been specifically processed to maximize Spherasorb absorption capacity. One kilogram of Spherasorb will absorb a minimum of 120 litres of CO2.

Bed packing

The consistently sized spheres allow for optimum bed packing compared with granular soda lime. This help to maximize the performance of the product, by ensuring that good gas flow is guaranteed, preventing gas channeling and the possibility of the gas bypassing regions of the Spherasorb inside the absorber.

Application

Spherasorb is designed specifically for medical use as a Carbon Dioxide absorbent. The absorption of Carbon Dioxide by soda lime results in an exothermic reaction. All Soda Lime brands will generate heat, especially if exposed to higher than normal expiratory levels of Carbon Dioxide.
