Automated Protein Hydrolysis System (APH)

Protein Hydrolysis for Pet Food Amino Acid Composition Analysis

Hands-Off Protein Hydrolysis and Sample Prep

The APH system is ideal for feed testing where incoming samples must be continually prepped for AAA. It increases efficiency and reproducibility and also frees laboratory technicians from performing the tedious tasks associated with hydrolysing large numbers of feed samples. The system automatically prepares the samples for hydrolysis in glass reaction vials, caps them, heats them, and then dilutes and filters the samples before transferring to HPLC sample vials.

The system shown above is based on a 2.5m long Lissy 2002 liquid handling workbench with two independently operating arms. Each arm is equipped with the viscous media dispenser and a gripper. Gripping tools are designed for transportation of the blending vessels and the tips of the viscous media tools. This system can be scaled smaller or larger depending on the throughput desired, and can also be configured with REDI solid dispensing tools for the addition of solid additives by weight.

Four 24-position heated reaction blocks for total walkaway capacity of 96 samples. Each block can be set for acid or base hydrolysis. The APH system is programmed by submitting a simple spreadsheet with the desired parameters. It will completely process 96 samples with acid or base hydrolysis with unattended operation.
