Description:   The determination of the gravitational constant ‘g’ is one of the most fundamental and early physical constants students must derive and observe. This kit has a wooden base, 1.1m rod and a movable electromagnet. The electromagnet can be moved anywhere on the rod and is powered by the timer. When the ball is released, the timer is triggered and stopped once the ball has landed on the base for a precise measurement and then calculation of ‘g’. Supplied with manual.

Description:   Lactose intolerance is common, but is actually a recessive genetic trait! Humans and other mammals are only meant to drink milk as infants and as they grow, they lose the ability to digest lactose. As populations began to develop, the domestication of cows and drinking milk into adulthood became more common, leading to a tolerance for lactose. Learn about variation, inheritance, and the role of DNA and proteins in expression of traits in this three-part laboratory activity.

Description:   10000 µl capacity non-sterile micropipette tips. Free from RNase, DNase, and endotoxins.

Description:   Erlenmeyer flask set consisting of a full range of five sizes: 50, 150, 250, 500, 1000 ml, all made from borosilicate glass with narrow necks, white markings, and beaded rims.

Description:   This laboratory set includes a retort base made of corrosion resistant, powder coated steel, a stainless steel rod featuring a 10 mm x 1.5 mm metric thread, a support ring and a three-pronged coated clamp.

Description:   This polystyrene slide box is durable, compact, and provides protection to 75×25 mm slides.

Description:   Every classroom that wants to investigate spectroscopy needs a good-quality spectrum tube and power supply.

Description:   Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.

Description:   Measure an electric current by determining the magnitude and direction of the horizontal component of Earth’s magnetic field. Set the compass needle parallel to the coil, pass an unknown current through, and measure the angle of deflection. Features copper magnet wire, adjustable potentiometer, compass, and non-magnetic stand. Required but not included is one D battery.

Description:   A very large Protozoa that graphically demonstrates the basic animal cell.<BR><BR>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.<BR><BR>Each culture shipment is prepared in our laboratories and includes the "Working with Protozoans" manual which contains detailed instructions for subculturing and use.<BR><BR>Canadian Customers:<BR>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.<BR><BR>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.)

Description:   Polished wood construction pipette rack capable of holding 12 pipettes horizontally, offering an organized and convenient storage solution for pipettes.

Description:   The Hermle Z287-A Compact Universal Centrifuge exceeds the limitations set forth by traditional microcentrifuges which are restricted solely to fixed angle rotors for microtubes. Instead, this compact, next generation model features an expansive line of swing out and fixed angle rotors options that accept microplates and test-tubes up to 50 ml. This centrifuge is designed to be our most compact and economical. It is a true workhorse for any lab requiring a centrifuge that can accommodate many fields of research.
