The Sentino® pump system is ideal for microbiological MF technique using Pall MicroFunnel™ filtration units. Designed to use peristaltic action to draw the sample through the filter and send filtrate directly to drain or waste collection. The housing is a PC ABS-blended polymer, the keypad and label PE, the pump head PEI with PTFE-filled PBT rollers. The fluid path adapter is PP.

Supplier: Merck

Sputofluol® can be used as pre-treatment solution for microscopy investigation of mycobacteria. It will release the mycobacteria from sputum and other material of human origin through the oxidative dissolution of organic material.

Supplier: VWR Chemicals

Sterile liquid paraffin is mostly used in microbiology as a vehicle to improve the anaerobic culture media as: O / F, decarboxylase medium, MIO, etc. Typically the product (approx 2 ml) is aseptically dispensed on the surface of the sterile culture medium in a culture tube.

Supplier: VWR Collection

The VWR® Star Blender 400 Silent is a highly efficient laboratory blender for solid sample preparation. With a sterile bag, it guarantees optimal bacterial extraction in less than 60 seconds, and eliminates all risks of cross contamination.

Supplier: EDVOTEK

In this experiment, students see a blue colour change in transformed cells due to the switching on of a gene. The pGAL plasmid gives a blue colour dye due to the production of the β-galactosidase protein by the lacZ gene. IPTG is not required in this experiment since pGAL contains the complete lacZ gene.

Supplier: EDVOTEK

Educational Materials, Microbiology, Application: Microbiology, ReadyPour™ LB agar with ampicillin

Supplier: OUTILS RUBIS

Stainless steel. Forceps with very precisely machined tips. Ideal for applications that require a high degree of precision, including microscopy, anatomy, biology, microbiology, gene technology and electron microscopy.

Supplier: EDVOTEK

In this experiment, transformed cells take up a plasmid containing the Green Fluorescent Protein (GFP) gene. The GFP gene was isolated from the jellyfish Aequorea victoria. Transformed colonies expressing the GFP protein are visibly green in normal light but will fluoresce brightly when exposed to longwave UV light.

Supplier: Merck

Kovac's indole reagent for microbiology pH <1 (H₂O, 20 °C), Millipore®

Supplier: VWR Collection

pH electrodes with 1 m fixed cable or S7 connector.

Supplier: Merck

Base ingredient for culture media

Supplier: Sterilin

PS, non treated. Used for serology and microbiology. Compatible with automated plate readers and washers.

Supplier: VWR Collection

Incubating microplate shaker with microprocessor control which holds up to four microplates or two microtube racks. The speed can be adjusted across a wide range to suit the application; a low speed ensures that the well contents are not ejected, more vigorous agitation provides effective aeration across the small surface area of each of the wells. Ideal for use in immunoassays, hybridisations, biotechnology, microbiology and pharmacology applications.

Supplier: EDVOTEK

The Green Fluorescent Protein (GFP) from the jellyfish Aequorea victoria is used extensively in all areas of science. Many organisms have been transformed with the GFP gene, the gene responsible for bioluminescence in jellyfish. It has proven to be so useful that scientists have mutated it to produce Blue Fluorescent Protein (BFP). In this simple experiment, students transform bacteria either by GFP, BFP or both.

Supplier: PanReac AppliChem

A reagent for the detection of indole-positive and indole-negative microorganisms. Some microorganisms can cleave tryptophan which is especially abundant in trypticalle digested peptone to give pyruvic acid, ammonia and indole. Indole then reacts with 4-dimethylaminobenzaldehyde to form a dark red dye. As tryptophan also gives a colour reaction with 4-dimethylaminobenzaldehyde, it must be separated from the indole. This is achieved by selectively extracting indole with butanol.

Supplier: VELP SCIENTIFIC

Compact magnetic stirrers which are ideal for microtitration, BOD, microbiology and biochemistry. The robust units are powerful and their technopolymer casing resists chemicals. MST Digital has a bright digital display for accurate speed monitoring and an on board timer (1 to 900 minutes or continuous mode) for unattended operation.

Supplier: Merck

This UV lamp is designed for use with Fluorocult® culture media.

Supplier: Anicrin

PS. Suitable for all microbiology applications.

Supplier: GERHARDT

Laboratory scale platform shakers, which are ideal for extractions, microbiology application and environmental analysis. The units have a stable base, which allows heavy loads to be handled for long periods of continuous use.

Supplier: EDVOTEK

When bacteria are used to make medicinally useful proteins by transformation, the protein of interest must be separated from all of the other cellular proteins. In this experiment, the unique fluorescent properties of GFP and BFP are used as an assay during their purification from an E. coli extract. The column fractions containing GFP or BFP are identified by fluorescence and then purified. As an optional activity, purified protein fractions can be separated by SDS polyacrylamide gel electrophoresis (SDS-PAGE) to estimate the purity and size of the GFP and BFP proteins.
