Formulation Characterization Testing of 5% Lidocaine Ointment

Project Description

URGENT

MULTIPLE TESTING

USA Pharmaceuticals analytical laboratory needed for formulation characterization analysis of 5% lidocaine ointment. The required analyses are as follows:

1. Microscopic Examination:
High-resolution microscopic imaging at multiple magnifications to characterize the phase states and structural organization of the ointment.

2. Rheological Behavior Characterization:
Using a rheometer suitable for semi-solid dosage forms to evaluate non-Newtonian flow behavior at both 25°C and 37°C. Tests to include:

- Shear stress vs. shear rate and

- viscosity vs. shear rate at three distinct shear rates (low, medium, and high).  A complete flow curve across attainable shear rates to identify low/high shear plateaus.

- Yield stress determination for plastic flow behavior (if applicable).

Could you confirm if your laboratory has the capacity and expertise to perform these analyses?

Additionally, we would appreciate details about the expected timeline, sample requirements, and cost estimates for these services.

Thank you for your time and assistance.
