MeltPrep at AAPS PharmSci 360 2020 

Discover the fastest way from powder to sample.

The MeltPrep VCM Technology is the first lossless method for the screening of thermoplastic dosage forms (e.g. amorphous solid dispersions or implants in the milligram to gram-scale such as ASDs or implants).

Hot-melt

Extrusion-like 

The VCM Process holds the balance between input and output material. It’s the first lossless approach to melt samples into a defined shape, without air inclusions. With 1 gram of powder, you will obtain a cylindrical sample of 1 gram with a defined shape.

We offer a broad range of VCM Tool Inserts starting from 25 mm (up to 5g) to 0.3 mm (down to 200 μg) to address your needs in material characterization and formulation development.

Intrinsic dissolution

MeltPrep samples can be used for intrinsic dissolution testing giving valuable insights into formulations characteristics. The samples have defined geometries and release the drug via a defined surface, thus specific drug release properties can be derived from testing.

DSC Measurements (Discs 5 mm)

Samples are placed in a crucible and subjected to a controlled heat transfer cycle. Particle boundaries hinder heat transfer. Homogeneous VCM samples ensure uniform heat transfer and will lead to more significant results.

Diffusion Studies  (Discs 8-25 mm)

Multilayer samples are requested in galenics to study drug diffusion and release. They are also used for controlled release drugs. A well-known example is the intra-vaginal birth control ring (IVR) from Merck (NuvaRing™).
