M.I.C.E.™ Strips


Oxoid M.I.C.E. Strips

Thermo Scientific™ M.I.C. Evaluator™ Strips

Combine the simplicity and ease of use of the diffusion method with the accuracy of an Minimum Inhibitory Concentration (MIC) test. Firm but flexible, Thermo Scientific™ M.I.C. Evaluator™ (M.I.C.E.™) strips are easy to handle and apply to pre-inoculated agar plates. Upon application, the antimicrobial is released from the strip, forming a clear, easy-to-read zone. Each M.I.C.E. strip is individually foil wrapped for ease of use and quality assurance.

  • User-friendly design features easy-to-read font size, for simple interpretation
  • Innovative single-sealed strip ensures product quality

Sensititre™ ID/AST System



Thermo Scientific™ Sensititre™ ID/AST System

Meeting the unique testing demands of all laboratory sizes and volumes, the Thermo Scientific™ Sensititre™ ID/AST System includes a full range of standard and custom MIC plates that allow you to eliminate offline testing while meeting CLSI and EUCAST breakpoint requirements, and FDA-established criteria.


Learn more

The Sensititre™ System utilises true MIC results, versus extrapolated [MIC] results, essential to fighting antimicrobial resistance for a number of reasons:

  • Greater sensitivity; provides better antimicrobial resistance tracking
  • Best measure of antibacterial effect; can assist with therapeutic choices
  • Preferred microbroth dilution test method
  • Superior quality and reproducibility for accurate results the first time, eliminating offline tests and retests.

The Sensititre System utilizes 96-well microtitre plates, available in both standard and custom formats, with in-vitro diagnostic (IVD) or research use only (RUO) markings. With over 240 antimicrobials available in extended dilution ranges on a wide variety of formats, the Sensititre System allows you to eliminate supplementary offline tests while meeting FDA, CLSI and EUCAST breakpoint requirements.

Combined with flexible equipment options, the Sensititre System allows you to create the ultimate test program tailored to your laboratory’s unique needs.

If you want to take advantage of the superior performance of Sensititre plates, but don’t have the volume to justify automation, plates can be inoculated with a multichannel pipette and read manually with a mirrored viewbox, or as your volume increases using one of our flexible instrumentation options.

Choose from a variety of flexible instrumentation options:


Oxoid™ Tubidometer

Oxoid Turbidometer

Thermo Scientific™ Oxoid™ Tubidometer

Improve reproducibility of inoculum suspension and acquire accurate and reliable Antimicrobial Susceptibility Testing (AST) results using the Thermo Scientific™ Oxoid™ Turbidometer. Standardise inoculum levels and ensure accurate and reliable Antimicrobial Susceptibility Testing (AST) results.


Use of a turbidometer allows a simple and quick method to enable complete control of your inoculum to the 0.5 McFarland standard. 

Simply calibrate your Turbidometer with a 0.5 McFarland standard, prepare your inoculum and insert into the test well. A green light will indicate the inoculum level is correct while an orange light indicates the inoculum level is incorrect.
