Steriwater: Pure water, instantly!

Sterile water is used in microbiology, cell culture and physico-chemistry laboratories, particularly in the preparation of culture media.

The preparation of sterile water is a time-consuming step that requires anticipation. Unlike a sterilization cycle at 121°C for 15 minutes, Steriwater is an instant water sterilization solution.

Steriwater, for all your sterile water needs in the laboratory
Steriwater is a range of products dedicated to the distribution of sterile water with gravimetric dilutors, peristaltic pumps, bags with media and distribution sets. Therefore it is suitable for applications related to sterile water production in laboratories.


  • Reduces sterile water production time
  • No need to autoclave the bottle and the water

Easy to use

  • No need to handle heavy loads and bottles
  • Reduces waste

Steriwater, ideal with instaBAG

  • Quick use of instaBAG, bag with pre-dosed dehydrated medium

How it works?

The water is sterilized using a 0.2 µm filter which removes biological contaminants, including bacteria, molds and yeasts.

The filter is connected to the tubing, the whole unit is sterile and is fitted to gravimetric dilutors and peristaltic pumps. The water flow is ensured by a mechanical action outside the tubing (without risk of cross-contamination) using a peristaltic block.

Sample dilution

Steriwater simplifies sample dilution with sterile water using a DiluFlow Elite gravimetric dilutor and instaBAG dehydrated media bags.

instaBAG is a filter bag that incorporates a pre-dosed dehydrated medium for 10g and 25g protocols diluted to the 10th. It is available in BPW, Fraser ½ and milk powder for solid sample preparation, pathogen testing according to ISO 7218 and ISO 4833-2.

Steriwater provides instant sterile water.

Connect the sterilized filter tubing to a bottle of purified water and a DiluFlow Elite dilutor.

Place an instaBAG bag on the gravimetric dilutor.

Select the instaBAG program

Weigh 10 to 25 g of sample and dilute to 1/10th with sterile purified water

Preparation of sterile water

Steriwater can also be used with a FlexiPump peristaltic pump to prepare sterile water.

Connect a sterilized filter tube and install it on the FlexiPump peristaltic pump.

Connect the tubing to the water bottle.

Dispense sterile purified water for the preparation of your media (tubes, bags, bottles).

Applications: Food / Public research / Environmental / Veterinary
