ISO-MISER ®, Circle Absorber, economy version. Patient weight above10 Kg.
Iso-Miser is the rationally designed replacement for the circular Polycarbonate CO2 absorber, generally known as the ‘Hamster Wheel’, which had many failings, the worst of which was the need for ‘extenders’ or ‘stand-off’ fittings to enable it to be connected to the fresh-gas outlet. On the Iso-Miser, the fresh gas inlet is a 22mm Female taper immediately behind the inspiratory port, in the top left-hand corner of the absorber. This allows it to be mounted directly onto most modern anaesthetic machines. Large directional valves offer minimal resistance to gas flow. A mushroom valve in the scavenging port is designed to relieve at 2 Cm H2O, which is near ideal back-pressure to lightly extend the reservoir bag, without having to ‘fiddle’ with the airway pressure limiting valve. Supplied complete with patient breathing tubing, 2 Litre reservoir bag, and 30mm to 22mm scavenging connector. Price £135

The RCVS Practice Standards section 5.12 paragraph 4 states:

"If a sophisticated active scavenging system is in operation, it must be serviced annually. A test certificate must be available and is an acceptable alternative to personal dosimetry."

Activent is a fan-driven, single-station anaesthetic pollution exhaust system, usually wall-mounted. Unlike Fluosorbers (which are bacterial hazards), Activent will remove all anaesthetic waste gases, including Nitrous Oxide. It is normally wall-mounted, adjacent to an Anaesthetic work-station. The design incorporates a fixed 3-Litre reservoir, with one end open to atmosphere via a safety inlet filter on top of the unit. This built-in AIR-BREAK acts as a safeguard against any possibility of the system generating a positive or negative pressure at the patient end. The filter is easily removed for cleaning. Activent draws between 5 and 15 Litres per minute of room air, into which the waste gas is very simply directed via standard 30mm connectors and 22mm flexible scavenging tubing (supplied). The air and waste-gas mixture is actively propelled to the point of disposal, up to a distance of 15 Metres. Flow-rate is adjustable to suit local installation conditions. Push-button "ON/OFF" control with Power "ON" indicator. A green L.E.D. illuminates to indicate when the fan is running, as the unit is near silent in operation. Easily installed using the Starter Kit (included in price). Easily connected to the patient-breathing-circuit APL / exhaust valve, using scavenging tubing & 22mm/30mm connector (supplied).
Activent can pay for itself in 12 months!!
E.G. 12 x Fluosorber @ £24 each = £288
Included in the price: 30-22mm connector with 2 Metres scavenging tubing, connects patient-circuit scavenging (APL) valve to Activent; ‘V’ plate & bracket wall-mounting kit; The A.C. to (adjustable) D.C. Power Supply Unit:
Installation Starter Kit, this is sufficient to take the waste gases up from the Activent, into a right angled connector, through a wall (22mm diameter hole) to the exterior of a building, terminating in a ‘tee-piece’. Customer may extend this system, to a maximum length of 15 Metres, using standard domestic 21.5 mm overflow tubing and connectors, readily and cheaply available from B&Q, Plumb-Centre, and most D.I.Y. stores.

SPHERASORB, Soda Lime. Low dust, low flow resistance.
Pink to white. 
Spherasorb is made of 3-4mm smooth-surfaced spheres, processed to minimise potential dusting. Its uniform shape allows consistent bed packing, resulting in a more even flow of anaesthetic gases, with less resistance to flow, through the absorber.
