Do you sell/ship to the USA?

Yes, we do supply our instruments directly with door-to-door delivery option by the parcel services to the USA.

What is the availability of the product?

We have the instruments in stock. We would just have to configure the instruments according to your requirements and perform quality control before shipping.

Is there a warranty?

We offer a 2 year warranty for MINIFOR fermentor / bioreactor and 5 year warranty for the PRECIFLOW & MULTIFLOW peristaltic pumps.

Does this fermentor work on both mammalian cells and yeast cells?

Yes, MINIFOR fermentor and bioreactor can be used for mammalian and yeast cell cultures (More information at www.fermentor.net/applications).

Is there flexibility in the top plate to add or remove probes?

Yes, MINIFOR has free ports in the headspace for the additional probes (sensors). Multiple ports and other effective solutions in the fermentation glass vess make the MINIFOR configuration equivalent to 16 to 22 classical ports (it is possible to increase the number of ports – custom made solution)

Is the equipment suitable for use in pure / mixed culture?

Yes, MINIFOR is suitable for pure as well as mixed culture. The stirrer is strong and can easily be adapted according to the types of cultures and working volumes.

Why is MINIFOR perfectly suitable for parallel processes?

Each unit stays independent as it is equipped with a control panel and display and at a single glance shows the parameter values. All parameters are regulated locally inside each fermenter-bioreactor unit.

This allows fast and precise parameter regulation and never having to worry about leaving a vessel unattended. Further advantage is that in case there are problems with one unit, the other units will still keep running.

How important is the slowdown in parameter regulation while running 12 bioreactors in parallel?

An important aspect to consider – which, however, does not play a role in the LAMBDA MINIFOR parallel system because each MINIFOR fermenter comes with its proper regulation unit that measures and controls all parameters locally. As a consequence the quality of the measurement and regulation is not affected by long transmission times and dead times in regulation.

How much space is required for the MINIFOR unit?

Footprint: approximately a sheet of paper
Dimensions: 22 cm x 38 cm x 40 cm (W x H x D)
