LIMS Software for Chemical Laboratories: Flexible, Configurable and Audit-Ready
Zeptac is LIMS software for chemical laboratories that brings samples, test methods, reagents, instruments, specifications and certificates of analysis into one traceable system. Whether you run a QC lab at a chemical, paint or agrochemical plant or an NABL-accredited chemical testing lab, Zeptac helps you release batches faster, catch out-of-specification results early and stay ready for ISO/IEC 17025 audits.
What Is LIMS Software for Chemical Laboratories?
LIMS software for chemical laboratories is a laboratory information management system that tracks chemical samples, test methods, calculations, reagents and reference standards, instruments, specifications and reports in one digital workflow. It replaces registers and spreadsheets, flags out-of-specification results automatically and produces the certificates of analysis and audit records that customers and assessors expect.
Why Chemical Labs Outgrow Spreadsheets
- Manual calculations for assay, titration factors, moisture and impurities invite formula and transcription errors.
- Reagents and standards expire unnoticed, putting every result that used them at risk.
- Batch release waits while results are retyped into certificates of analysis.
- Specifications differ by product, grade and customer, and comparing them by eye is slow.
- Instrument records are scattered for HPLC, GC, spectrometers, titrators, balances and pH meters.
- Audits take days of searching for raw data, method validation and training records.
The quality burden is shifting, not shrinking. On 12 November 2025 India revoked 14 Quality Control Orders covering chemicals and polymers such as ethylene glycol, PVC, polypropylene and polycarbonate, removing mandatory BIS certification for them. Buyers still expect a reliable certificate of analysis with every batch, so in-house QC labs carry more of the responsibility for proving quality.
Flexible & Configurable LIMS for Chemical Labs
A specialty chemicals plant, a paint factory and a third-party testing lab all test different products against different limits. Zeptac is a Flexible & Configurable LIMS, so you set it up around your products, methods and approvals instead of changing your lab to fit the software.
- Configurable test masters with your methods, parameters, units and reporting rules
- Product-wise specifications for each product, grade or customer
- Configurable calculation formulas for assay, titration, moisture, loss on drying and more
- Configurable certificate templates and approval levels with role-based access
- Room to grow as you add products, methods, instruments or sites
Sample Registration and Chain of Custody
In Zeptac’s LIMS software for chemical laboratories, every sample is registered with its product, batch, source and customer, whether it is a raw material, an in-process sample or a finished batch. Chain of custody follows the sample from receipt to testing, retention and disposal.
- Sample, batch and test details in one record
- Customer service requests and inquiry management for testing labs
- Inward and outward challans for full movement history
- Retained sample records for complaints and re-testing
Reagent, Standard and Chemical Inventory Management
Chemical results are only as reliable as the reagents and reference standards behind them. Zeptac keeps a register of reagents, volumetric solutions and certified reference materials with lot numbers and expiry dates, so analysts never use an expired standard by mistake.
- Lot numbers, suppliers, certificates and expiry dates for reagents and standards
- Expiry alerts before a reagent or standard goes out of date
- Preparation and standardization records for in-house solutions
- Link between the standards used and every result reported
Calculations, Specifications and Certificates of Analysis
Analysts enter raw readings and Zeptac calculates the result, compares it with the product specification and flags anything out of limits. Once approved, a certificate of analysis is generated instantly in your configured format.
- Consistent calculations across every analyst and shift
- Automatic out-of-specification flags against product limits
- Instant reports and certificates of analysis after review and authorization
- Searchable history by product, batch and customer for trend reviews
Instrument Records, Uncertainty and Internal Audits
As LIMS software for chemical laboratories, Zeptac keeps maintenance and calibration records for HPLC, GC, ICP and AAS systems, UV-Vis spectrophotometers, Karl Fischer titrators, balances, pipettes and pH meters, and links to CalTac calibration management software for calibration management.
- Instrument maintenance records and calibration due-date alerts
- Automated Type A and Type B uncertainty calculations
- Internal audit management with corrective action follow-up
- Employee records with training and authorizations

Chemical Store and Lab Environment Monitoring with IoT
Reagents, standards and samples degrade when they are stored wrongly. With the Zeptac IoT platform, labs monitor chemical stores, reagent refrigerators, stability areas and lab rooms continuously, with alerts the moment conditions drift.
- Continuous temperature and humidity logging
- Instant alerts by email and mobile notification
- Time-stamped records for audits
- Environmental data that supports ISO/IEC 17025 clause 6.3
