HiPette is a line of high-performing science education micropipettes for when laboratory-grade precision is needed.

Used for incubating diluted samples to determine biological oxygen demand.

A set of dynamic cart trolleys are used for investigation on momentum, velocity and acceleration. Each trolley consists of two rectangular wooden blocks, 300 mm long, moving on three low friction wheels (ball bearings in wheels). The trolley is fitted with spring loaded impulse rod. It has a provision for stacking the trolleys on top of each other with removable pins. It is supplied with two rubber corks and 2 needles, so trolleys may be stuck together for inelastic collisions. A striking pin for releasing the striker and 3 pins or dowels for stacking are provided. One trolley weight approximately 1 kg.

Economical laser pointer, useful for many optical experiments.

Medium weight with wide flared top.

Perfect for chemistry demonstrations and experiements.

Funnels feature short, wide stems, and are useful for adding powder chemical to reaction vessels.

Engage students with a genetics and PCR kit that has a direct link to a testable phenotype.

This unique skin model shows three layers of skin.

This lightweight mixing plate is perfect for small laboratory tasks. Weighing in at about two pounds, it's small but mighty.

Large industrial funnels made of polypropylene.

Vigreux distilling columns for cooling and condensing.

Graham condensers are designed for use in distillation applications.

The Universal Specific Gravity Kit is designed to be used with any electronic scale with a minimum capacity of 15 grams and a tare (re-zeroing) function to easily measure the specific gravity of gemstones and minerals.
Just weigh the stone "in air" on the integrated weighing platform of the scale, then without changing the setup, weigh the stone in water by placing it in the underwater weighing pan of the gem holder suspended above the platform. Plug the two values into the specific gravity equation and obtain the specific gravity of your stone.

Includes: lightweight gem holder support and underwater weighing pan, independent, spill-resistant, adjustable beaker support, beaker for filling with water - 100ml capacity, aluminum test weight, stainless steel tweezers, instructions, reproducible Specific Gravity worksheet, table of 300 common minerals/gems sorted by SG, with 6 other properties, including refractive index.

Note: shown with Boreal Balance - not included.

Measuring apparatus for investigating the elastic deformation of rods of flat geometry and for determining the modulus of elasticity.
