Interscience : What floorutions for preparing, inoculating and analysing samples in microbiology?

Interscience designs and manufactures in France integrated solutions for microbiology: sample preparation, gravimetric dilution, automated plating, incubation and colony counting. Widely used in agri-food, environmental, pharmaceutical and cosmetics laboratories, the brand safeguards the entire CFU workflow with robust instruments (BagMixer, DiluFlow, easySpiral, Scan, ScanStation) and sterile consumables. Traceability, productivity and reproducibility are at the heart of every analysis series.

A French pioneer in applied microbiology

Founded in France in the late 1970s, Interscience was built on a simple belief: to standardise and speed up microbiological analyses without compromising quality. Early on, the BagMixer became the benchmark paddle blender for sample preparation. It was followed by DiluFlow gravimetric diluters, easySpiral spiral plating, and then Scan colony counters. The latest major step, ScanStation, unites incubation and real-time counting, letting you watch colonies appear and bring decisions forward by hours. As an independent brand, Interscience combines rigorous manufacturing, local support and a global network that now equips thousands of quality control (QC), R&D and production laboratories worldwide.

Expertise and areas of specialisation

At Interscience, expertise spans the entire microbiology workflow. Upstream, BagMixer paddle blenders deliver gentle, efficient homogenisation in sterile BagFilter/BagLight/BagPage bags that simplify clarification and minimise transfers. DiluFlow gravimetric dilution dispenses diluent to the gram, with traceability and repeatability to secure series preparation. For dispensing culture media and diluents, FlexiPump brings accuracy, ergonomics and easy cleaning. For plating, easySpiral (and its variants) deploys spiral plating to extend the countable range on a single plate and cut consumables and hands-on time. Colony counting is handled by Scan systems (HD acquisition, calibrated lighting, data export) and, for high-throughput labs, by ScanStation, which combines incubation with real-time automated counting, providing early alerts and growth-curve tracking. The whole ecosystem is designed for food safety, environmental, pharma/cosmetics and bioproduction laboratories, where reproducibility, traceability and documentation compliance make the difference. Rugged instruments, sterile consumables, tracking software and LIMS connectivity: everything is aligned to deliver reliable results, faster.

Frequently asked questions about the Interscience brand

Are Interscience instruments made in France?
Yes, a large proportion is designed and manufactured in France, a mark of quality, readily available spare parts and reliable metrological traceability. Local teams provide installation, training and after-sales support.

What are the main applications?
Microbiological quality control in food & beverage, water/environment, pharma/cosmetics and veterinary labs: from sample preparation to colony counting, in line with standard methods.

Does easySpiral replace serial dilutions?
It reduces the number of dilutions and plates by widening the countable range on a single plate. In-house validation is still required according to your methods and matrices.

What does ScanStation change day to day?
Automated incubation and real-time counting: early CFU detection, complete traceability, fewer manual steps and fewer errors. Capacities suited to routine throughput.

Are the bags sterile and compatible?
BagFilter/BagLight/BagPage are sterile and designed for BagMixer and DiluFlow. Compatible with common media, with no interference with standard methods.

What about traceability and compliance?
The instruments embed IDs, logs and data export for audits. Software options make LIMS connectivity straightforward. Compliance documentation is available per product.
