Lustrous, black 'hard coal'.

When minerals, rocks, and fossils cannot be accurately identified by macroscopic observation and testing, thin section slides can reveal the composition and structure of the specimens on a microscopic level.

Give your students a piece of outerspace.

Two strains of Escherichia coli (donor and host) with complementary sensitivities to Ampicillin and Streptomycin. Watch them trade traits via conjugation.

Ideal for comparative study, the four cultures included in this set represent green algae's variety of physical morphologies.

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.
