Experimentation kits, water quality testing I: chromogenic analysis of water bacteria contaminants

Artikkenummer: (EDVO951)
Produsent: EDVOTEK
Beskrivelse: Safe drinking water is vitally important to health. Both pathogenic and harmless bacteria can be found in the guts of mammals and birds. Testing water for every possible type of pathogenic bacteria is slow and costly. Thus, water is tested for a characteristic type of gut bacteria - the coliforms - including the familiar <i>E. coli</i>. Presence of coliforms is an indicator for faecal contamination. In this experiment, students test for coliforms in simulated contaminated water using colour and fluorescent reagents. They can use these same reagents to test water samples from the environment. As an extension activity, a Gram Stain test can be performed on the collected samples.

Experimentation kit, bioremediation by oil eating bacteria

Artikkenummer: (EDVO956)
Produsent: EDVOTEK
Beskrivelse: Oil spills cause devastation to the environment, killing sea life, birds, and coastal plants. Spraying areas of contamination with oil-eating microbes accelerates the degradation of the oil. This process is known as bioremediation. In this open-ended experiment, students grow a mixture of oil-eating bacteria and observe their effectiveness at degrading a variety of oils.

Product Image-BE-403

Experimentation kits: biodiversity study and biomass analysis

Artikkenummer: (BE-403)
Produsent: G-Biosciences
Beskrivelse: Biodiversity lab activity is designed for determination of protein contents and biomass in diverse biological samples to study how biomass is related to biodiversity in nature. Students collect and catalogue plant leaf samples from a diverse group of locally available plants. This lab activity involves determination of natural weight of each plant sample, grinding a predetermined amount of each sample, and the subsequent extraction of proteins from the samples. Students then learn to determine protein contents of each plant sample and attempt to relate the protein content with biomass. Students in this lab activity are challenged to think, analyse, and seek answers as to why protein biomasses vary for a given natural weight for different plants. Finally, they will relate that finding to the biodiversity of nature.

Experimentation kits, bacterial conjugation

Artikkenummer: (BE-301)
Produsent: G-Biosciences
Beskrivelse: Bacterial conjugation is a naturally occurring process that allows the transfer of DNA from one bacterium to another, which allows the transfer of genetic traits, particularly drug resistance. The kit contains two bacteria with different drug resistance genes and all the tools for students to study bacterial conjugation. This kit teaches the difference between bacterial genomic DNA and the transferable plasmid DNA and the mechanisms of bacterial conjugation. Students will also learn important basic microbiological techniques, including bacterial growth in liquid broth and on solid agar plates, antibiotic selection of bacteria and important aseptic techniques.

Product Image-BE-314

Experimentation kits, mutation detection and analysis

Artikkenummer: (BE-314)
Produsent: G-Biosciences
Beskrivelse: A major challenge for molecular biologists and genetic engineers is to easily detect and analyze genetic mutations that occur naturally, causing diseases, or during genetic engineering or cloning, whether deliberate or accidental. Students learn about different types of genetic mutations, including substitutions, deletions and point mutations and about various techniques used to detect genetic mutations. The kit contains all the reagents to screen simulated clinical samples for a mutant gene, using both the polymerase chain reaction (PCR) and restriction digestion mapping. Students conduct a simple clinical diagnostic experiment in order to identify a diseased patient.

Fog chamber

Artikkenummer: (765-1233)
Produsent: PHYWE
Beskrivelse: A fog chamber from the well-known physics company PHYWE is the given focus of many exhibitions. Every day, thousands of visitors to technical museums, art museums, nuclear power plant information centers, universities and colleges are fascinated by these fog chambers that make the invisible background radiation visible. PHYWE has been developing and manufacturing these unique devices for more than 20 years. In total, there are more than 200 in operation in more than 40 countries. The fog chamber makes the invisible visible. Every second you can observe a large number of traces that originate from both cosmic radiation and the earth's natural radioactivity. The appearance of the trace immediately reveals the type of particle that has just passed. During normal operation, no additional preparation is used. If you want to increase the activity in the surface, you can blow in a thorium isotope.

Experimentation kits, physical properties of proteins

Artikkenummer: (BE-401)
Produsent: G-Biosciences
Beskrivelse: The physical properties of proteins kit is a lab activity that enables students to investigate the physical properties of several different proteins. Students will learn about protein solubility and how it is affected by various parameters; including temperature, pH, salt and dielectric constant. They will understand about protein precipitation due to pH, high salt and in the presence of organic solvents and about protein denaturation as a result of high temperature. In addition, the kit will demonstrate how non-protein agents, such as detergents drastically alter the physical properties of protein molecules and as a result, understand the importance of detergents in protein solubilisation. This lab activity involves analysis of three different types of pure proteins and then students alter some of those properties with a detergent and re-examine physical properties of those proteins. Students are challenged to consider how physical properties of protein molecules can be exploited for purification and characterisation of proteins and apply their findings on a test sample of complex tissue extract.
