Dissolution Tester
QualiPharma™ DIS & DIS SA Series — USP <711> / EP / JP / 21 CFR Part 11 Compliant
A Dissolution Tester is a precision pharmaceutical instrument that measures the rate and extent at which an active pharmaceutical ingredient (API) is released from its dosage form — tablet, capsule, modified-release matrix, transdermal patch — into a controlled aqueous medium that simulates physiological conditions. Dissolution testing is one of the most rigorously regulated and most frequently performed tests in pharmaceutical quality control: it predicts in-vivo bioavailability, confirms batch-to-batch consistency, supports bioequivalence claims for generic drugs, demonstrates GMP compliance during FDA pre-approval inspections, and provides the foundational data on which every NDA, ANDA, and Marketing Authorization Application depends.
Pharmacopeial standards codify dissolution testing with extraordinary precision. USP <711> Dissolution, USP <1092> Dissolution Procedure Development & Validation, EP 2.9.3, and JP 6.10 describe standardized apparatus configurations — Apparatus 1 (Basket), 2 (Paddle), 5 (Paddle-over-Disc), and 6 (Rotating Cylinder) — operating under defined conditions of 37 °C ± 0.5 °C bath temperature, precise rotational speed, and rigid hydrodynamic equivalence. Modern instruments must additionally satisfy FDA 21 CFR Part 11 electronic-record requirements, 21 CFR Part 211 cGMP laboratory controls, and ICH Q1A stability-testing protocols — delivering complete audit trails, electronic signatures, and tamper-proof records that pharmaceutical regulators now demand.
Qualitest offers a comprehensive four-platform QualiPharma™ Dissolution Tester portfolio. The QualiPharma™ DIS 2008 (Automated) is the entry 8-vessel automated platform for routine QC and R&D. The QualiPharma™ DIS 2014 (Advanced) is the 14-vessel comparative dissolution platform engineered for bioequivalence studies of generic vs innovator drug formulations. The QualiPharma™ DIS SA 2008 is the fully integrated 8-channel dissolution + automated sampling + media-replenishment system, combining an 8-channel imported precision syringe pump with multi-method dissolution apparatus, segmented-shaft design that eliminates height re-adjustment on method changeover, a square integrated water bath with arc corners and bottom-drain, and 21 CFR Part 11-aligned data integrity (40 user accounts, 3-tier access, encrypted audit trail, thermal printer). And the flagship QualiPharma™ DIS SA 2014 (Advanced) delivers production-ready FDA audit-ready performance: 316L stainless steel segmented propeller shaft, multi-point SS guide rod machine head, embedded fixing-hoop dissolution vessels, imported PTFE micro-transparent sampling pipelines, eight independent temperature probes (one per vessel), 10-inch color touchscreen, AIQ IQ/OQ/PQ certification services, and minimum 2-minute sampling interval for the most demanding ICH Q1A multi-point dissolution profiles.

Why Choose Qualitest for Your Dissolution Testing Needs
Qualitest is a globally recognized supplier of advanced pharmaceutical and analytical testing instruments, serving customers worldwide with one of the most comprehensive dissolution testing portfolios available — engineered specifically for the rigorous demands of modern pharmaceutical regulatory environments.
Four-Tier Portfolio — One Trusted Source
From the high-precision 8-vessel QualiPharma™ DIS 2008, through the 14-vessel comparative QualiPharma™ DIS 2014, to the fully-integrated QualiPharma™ DIS SA 2008 dissolution + sampling system, and the flagship FDA-audit-ready DIS SA 2014 with AIQ certification services — Qualitest offers a coordinated portfolio that matches every pharmaceutical-laboratory size, throughput, and compliance requirement.
Full FDA 21 CFR Part 11 & cGMP Compliance
The QualiPharma™ DIS 2014, QualiPharma™ DIS SA 2008, and QualiPharma™ DIS SA 2014 deliver complete 21 CFR Part 11 technical controls — three-tier account hierarchy (administrator, advanced user, operator), encrypted non-modifiable audit logs with account identity and timestamp, electronic signatures, and tamper-proof records. Combined with 21 CFR Part 211 Subpart I laboratory-controls compliance and the AIQ IQ/OQ/PQ documentation supplied with the QualiPharma™ DIS SA 2014, every audit and inspection is supported from day one.
Premium 316L Stainless Steel & PTFE Engineering
The flagship DIS SA 2014 features 316L stainless steel segmented propeller shafts, multi-point stainless steel guide rod machine heads, embedded fixing-hoop dissolution vessels (with indicator strips and diagonal cup-rim fixtures for superior vessel-to-vessel reproducibility), and imported PTFE micro-transparent anti-corrosion / anti-adsorption sampling pipelines — eliminating API binding to pipeline walls and ensuring sample integrity across every time point.
Eight Independent Temperature Probes
The QualiPharma™ DIS SA 2014 monitors each dissolution vessel with its own dedicated temperature probe — eight probes total — eliminating thermal variability as a source of inter-vessel dissolution data scatter. Combined with PID + fuzzy control delivering ≤ ±0.2 °C accuracy at 0.1 °C resolution, the system maintains the precise hydrodynamic and thermal conditions that pharmacopeial standards demand.
Automated Sampling, Replenishment & Cleaning
The QualiPharma™ DIS SA series autosamplers automate the complete sample-handling workflow: pre-rinsing, filling, waste disposal, sampling, automatic media replenishment (critical for sink-condition maintenance in extended-release testing), dilution, secondary filtration, and one-click post-run pipeline + vessel cleaning — eliminating operator variability across high-volume workflows.
Bioequivalence-Ready 14-Vessel Architecture
The QualiPharma™ DIS 2014's unique 14-vessel design supports 6+1, 12+2, and 7+7 stirring configurations — uniquely enabling two dissolution methods to run simultaneously or independently on the same instrument. This is the gold-standard architecture for comparative bioequivalence studies of generic vs innovator drug formulations.
Cost-Effective Value & Global Support
Qualitest delivers premium dissolution-testing performance at a transparent, competitive price point — backed by global service, training, AIQ IQ/OQ/PQ qualification, mechanical verification certificates, calibration services, and stocked spare parts. Worldwide presence ensures expert installation, operator training, and ongoing regulatory-compliance assistance are always within reach.
Dissolve with Precision. Approve with Confidence.
In every pharmaceutical company on Earth, the dissolution tester is the gatekeeper of bioavailability — the silent instrument that decides whether a tablet will actually deliver its API as intended, whether a generic drug will achieve bioequivalence with its innovator reference, and whether a regulatory submission will pass FDA review or trigger a costly Refuse-to-File. A poorly performing dissolution program means failed batch releases, blocked product launches, GMP warning letters, recalled inventory, and lost market access. The pharmaceutical manufacturers, generic-drug developers, R&D scientists, and QC professionals who consistently launch compliant, bioavailable, regulator-approved products are the ones equipped with dissolution testers built for pharmacopeial accuracy, full automation, and FDA 21 CFR Part 11 data integrity — and the Qualitest QualiPharma™ portfolio gives you exactly that.
Whether you are running routine batch-release QC, supporting generic-drug bioequivalence studies, developing modified-release formulations, building a CRO contract-research operation, or preparing an NDA / ANDA / 505(b)(2) submission, Qualitest has the dissolution-testing platform engineered to meet your exact needs. From the entry QualiPharma™ DIS 2008 to the bioequivalence-ready DIS 2014 and the integrated QualiPharma™ DIS SA 2008 / QualiPharma™ DIS SA 2014 sampling-system flagships, every Qualitest dissolution tester delivers world-class regulatory-compliant performance backed by industry-leading service and support.
