Sampling Head Option

The MicroBio MB2 can be purchased with the option of one of two types of sampling heads.  The MicroBio MB2 will be calibrated for use with the selected head.  If swapping to another head type, the MicroBio MB2 must be re-calibrated.

220 x 1 mm hole stainless steel head

This is the standard head sold with the MicroBio MB2 and MB1 air samplers.  It is designed as a dual purpose head for both 55/60mm contact plates or up to 90mm Petri dishes.  The d50 cut-off point os 1.7 um and has a jet velocity of 9.63 m/s.  It is the ideal head for general purpose sampling in air quality and food production.

MicroBio 220 Hole Sampling Head

400 x 0.7 mm hole anodised aluminium head

Available as a no-cost option, this head provides full coverage of 90mm Petri dishes with a d50 point of 1.35 um and air jet velocity of 10.7 m/s.  These heads are ideal for use in areas needed higher sensitivity of collection.
