"Ward's Science"

Use Color Transition of Titration to Determine Water Hardness.

Freshwater. Colonial; net-like structure with multinucleated cells. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

The body of this ciliate is transparent, making the large cilia clearly visible.

Live Cultures are supplied with media in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars. Fast delivery is available directly from our laboratory. Please specify a delivery date.

Each culture shipment is prepared in our laboratories and includes the "Working with Protozoans" manual which contains detailed instructions for subculturing and use.

Canadian Customers:
CFIA and PHAC regulations require customers to submit a completed inspection checklist and signed statement of facilities compliance before receiving certain cultures. A customer service representative will contact you if documentation is required.

Our cultures undergo strict biochemical screening and are unconditionally guaranteed for species and purity. Each culture is labeled with scientific name, media on which it was cultivated and optimum growth temperature. Although our cultures are considered non-pathogenic, standard bacteriological laboratory procedures should be used at all times. Cultures are available either live for immediate use or freeze-dried for convenient storage until needed. (Please note: We are not responsible for any infection resulting from the use of our cultures.)
