This organism can be isolated from many human urinary tract infections, as well as polluted water and sewage. It is commonly identified by its distinctive grape-like smell (trimethylamine) or because it can turn the agar light green due to production of a blue pigment (pyocyanin).

This harmless insect parasitizes the Sarcophaga (flesh fly) pupae. Females usually lay 30–50 eggs in the pupae, which provide food for the Nasonia larvae when they hatch.

All of our most popular crosses, already done for you. We'll do all the pre-work, so you can spend more time with your students.

Dissect authentically, like cardiologists and medical industry professionals do today.

The set includes 200 heparinized, mylar wrapped, hematocrit tubes, and six capillary tube trays with sealant. Each tray has two rows of slots numbered 1 through 24 for easy tube storage.

Freshwater; unbranched filaments with cylindrical- to slightly barrel-shaped cells; shows the characteristic H-pieces upon fragmentation of the filament.

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 Algae & Cyanobacteria" 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.

Organized, economical survey of fossils.

Four to six adults of each sex (including virgin females) have been carefully selected for the parent generation. Larvae will be visible within a week of receipt. Please order 7-10 days in advance.

We fully guarantee the purity and viability of our Drosophila melanogaster cultures. A large, vigorous culture is shipped in a shatterproof plastic vial. To ship Drosophila cultures with living larvae we require 10 days' notice prior to use date. During very cold weather, adult flies may die but eggs and larvae usually survive. Allow cultures to come to room temperature before checking under low magnification for eggs and live larvae. Complete instructions are always included.

These environmentally safe thermometers are PFA safety coated to keep liquid and glass contained in the event of breakage.
