Circular MNS vs Square Eco Autoclaves

We compare both ranges to help you choose the best sterilizer for your requirements.

Astell Scientific manufactures autoclaves in capacities from 33 up to 2,000 litres. Typically, small units use a circular section chamber design and large units a square. In the middle of that size range it is possible to choose a model with either shape. But which is best? Below we highlight the standout features to help you identify their differences.

Benefits across both ranges
  • Integral sliding door simplifies loading access
  • Cabinet design and sliding door minimises footprint
  • Colour touchscreen controller provides efficient and secure cycle management
  • 316L stainless steel chamber is electropolished for improved cleaning and uniformity
  • All autoclaves are compliant with latest industry standards including, PED 2014/68/EU, BS EN 13060:2014 and ISO 9001:2015

As always, selecting a sterilizer should be determined firstly by the load type(s) and secondly by the frequency of processing and/or the available space for the unit. There is overlap in what loads each of these two ranges can sterilize, and in some cases optional extras may be necessary.

Astell is well positioned to recommend a suitable autoclave with its extensive experience and manufacturing expertise in both circular and square section designs. Reference the case studies and customer testimonials for further validation.
