Marine. Unicellular; small, centric cells. Marine medium.Characterized by shells (tests) made of silica, in two parts.

Freshwater. Filamentous; H-shaped cell walls. Soil-water medium.

Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Unicellular; lunate. Proteose agar.

Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Unicellular; triangular desmid. Basic culture solution. Characterized by green plastids and cell walls composed of cellulose.

Marine. Unicellular; brackish, centric cells. Marine medium.

Characterized by shells (tests) made of silica, in two parts.

Freshwater. Unicellular; pennate, with bilateral symmetry. Basic culture solution.

Characterized by shells (tests) made of silica, in two parts.

This filamentous cyanobacteria is comprised of heterocysts and akinetes that are terminally located on the filament.

Freshwater. Filamentous. True branching, dimorphic structure. Basic culture solution.

Shipped in a form that provides the best quality specimen. Most are supplied in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars..

Marine. Filamentous; unbranched thallus. Erdschreiber’s medium.

Characterized by reddish plastids (rhodoplasts).

Freshwater. Unicellular; heart-shaped cell. Soil-water medium.

Characterized by a lack of rigid cellulosic walls, instead these organisms have pellicles made of protein. They store paramylon instead of starch.

Marine. Unicellular. Erdschreiber’s medium.

Characterized by reddish plastids (rhodoplasts).

Marine. Unicellular; contains same pigments as other Golden Algae but contains haptonema, unique to Haptophyceae. Coccoid, from coccoliths. Marine medium. Characterized by golden yellow plastids.

Axenic culture. Food organism. Tetrahymena medium.

Characterized by cilia; nearly all possess two types of nuclei.

The culture supplied includes copepods in various stages of development.

Predatory. Feeds on Paramecium caudatum. Hay medium.

Characterized by cilia; nearly all possess two types of nuclei.

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.)
