Documentation, equivalence data, pharmacopoeial references, and support materials for VerisQ and MicroDome products.

Equivalence Data

NCTC-ATCC Reference Equivalence

We maintain formal equivalence documentation linking all VerisQ strains (sourced from NCTC/NCPF) to their commonly cited ATCC counterparts. This resource is essential for regulatory submissions, method transfers, and QA documentation. Access the full NCTC-ATCC equivalence matrix below:

Frequently Asked Questions

What is the shelf life of VerisQ products?
VerisQ lyophilised pellets are stable for 24 months from manufacture when stored at ≤ −18°C (frozen). Reconstitution solution is stored at 2–30°C. Exact expiry dates are printed on each product label and COA.
Are VerisQ strains validated for use in USP <61> testing?
Yes. All VerisQ strains sourced from NCTC and NCPF are covered by equivalence statements linking them to ATCC references cited in USP <61>. These statements are available for download and provide regulatory documentation for QA audits.
Can VerisQ be used for sterilisation process validation?
No. VerisQ is specifically designed for pharmaceutical quality control testing (contamination monitoring) only. For sterilisation validation, use MicroDome biological indicators, which are ISO 11138 compliant.
What does the UKHSA licence restrict?
VerisQ products are licensed for non-therapeutic pharmaceutical quality control testing only. Use is restricted to laboratory QC testing environments. Therapeutic applications are not permitted under the UKHSA Culture Collections licence.
How do I interpret the CFU count on a VerisQ COA?
The CFU count listed on the COA represents the viable organism count per pellet at the time of manufacture. This count is determined using validated microbiological enumeration methods. All VerisQ products are delivered with a defined, quantified CFU count — there is no requirement for serial dilutions.
Are MicroDome indicators compatible with rapid readout systems?
Yes. MicroDome offers both conventional (24–48 hour) and rapid readout biological indicators (2–3 hours) for various sterilisation methods. Consult technical data sheets on www.microdome.cn for specific readout time options.
Can I request custom VerisQ formats for my laboratory?
VerisQ is available in three standard formats (SS, GP, TK). Custom organism panels or CFU specifications may be possible for large volume orders. Contact sales@lotustech.com.au to discuss custom requirements.
What support does LotusTech provide for regulatory submissions?
We provide equivalence statements, COAs, regulatory documentation, and technical consultation to support pharmaceutical dossier submissions and QA audits. Contact us at sales@lotustech.com.au for detailed regulatory support.
