A screening trial being performed on papers from the EU

Development Trial

The development trial is generally used to follow up a screening trial that is successful but where the customer desires further refinement of the treatment. Micrex feels that the development cycle is important in cases where the product resulting from the screening trial has the potential for further improvement.

By running larger quantities of material while making additional adjustments to the machinery, improvements can be realized before going to a full production type trial.  Development trials also allow a customer to do extensive testing or even pre-production manufacturing of a product. Another beneficial aspect of the development trial is that it allows for the exploration of different Microcreper configurations.

Micrex does charge a fee (starting at $375 per hour) for development trials. The fee is determined by time, labor, materials, etc. More specific information concerning the trial fee schedule can be obtained from Micrex.

Production Trial

The production trial is the final step in verifying the successful application of the Micrex process to a particular product. In the production trial, Micrex seeks to simulate the conditions under which the product will actually be produced.

When Micrex machines are sold as a result of successful development or production trials, a portion of the lab fees may be credited against machine purchases.  The base rate for contract converting is $275.00 per hour.

The customer may also wish to arrange for a representative to visit Micrex during a development or production trial. Micrex encourages, and can facilitate, such a visit by helping to arrange lodgings, car rentals, etc.
