Quality Control Testing

Confirm the correct components were used to manufacture your reagent and detect any impurities by testing for unique absorbance spectra when exposed to light. This analysis verifies formulation accuracy prior to lot release.

Measure the refractive index of your reagent to confirm whether the formulation matches its intended composition. This provides an additional checkpoint for concentration verification prior to lot approval.

Verify that your buffer’s pH values fall within defined limits before release. Accurate pH control offers optimal reaction conditions and helps ensure reliable, reproducible outcomes downstream.

Ensure your buffer is prepared at the intended concentration and meets specified limits before release. Measuring electrical conductivity quantifies the ionic strength of a substance, in turn assessing solute concentration.

Verify that the correct ingredient amounts were added and confirm they align with initial calculations. Density testing measures solution mass per volume and compares it to target values, supporting consistent, reproducible batches.

Confirm whether reagent and buffer formulations were prepared correctly with osmolality testing, which measures dissolved particles in solution. This test detects formulation errors that other tests may miss, maintaining consistent performance.

Measure solution viscosity to confirm flow properties and physical uniformity. Verifying viscosity supports uniform mixing and prevents precipitation, maintaining performance from production through final use.

Monitor how your buffer performs and maintains specifications over time. Stability testing evaluates the shelf life of products, enabling informed storage decisions and reliable long-term use.

Detect bacterial endotoxins that may interfere with biological processes and regulated applications. Endotoxin testing protects against contamination that can trigger inflammatory responses in humans and animals.

Detect microbial presence with this rapid turnaround test. Here, microbial growth is expedited to reveal potential reagent contamination. Identifying microbial risks early ensures the safety of downstream applications.

Screen your reagent for DNase contamination to confirm it is free of nucleases. This test safeguards DNA-based downstream applications, such as PCR and sequencing.

Screen your reagent for RNase contamination to confirm it is free of nucleases. This test helps preserve RNA yield and maintain confidence in downstream RNA analyses.

Detect and quantify microbial presence in your reagent. Identifying contamination early helps safeguard product integrity, reduces downstream risk, and ensures your reagent is suitable for its intended application.

Verify that membrane filters used in sterile filtration function properly and retain bacteria and other microorganisms. This non-destructive bubble-point filter test supports product sterility and reinforces batch consistency.

Screen for protease enzymes that may compromise protein-based applications. This testing helps prevent unintended protein degradation, supporting analytical and biological workflows.

Test your reagent for the absence of viable microorganisms to confirm sterile manufacturing conditions. Sterility testing verifies aseptic control and helps protect product safety in regulated and sensitive applications.
