The replacement chemicals kit contains 5g each of calcium chloride, cupric chloride, cupric nitrate, lithium chloride, potassium chloride, potassium nitrate, sodium bicarbonate, sodium chloride, strontium chloride and strontium nitrate.

The 200 pound standard head Baseline hand dynamometer has become a popular tool used by therapists all across the world. The standard 2 1/2” diameter head is used throughout the industry. This Baseline Hydraulic Hand Dynamometer gives accurate grip strength readings without the subject being able to "feel" the handle move.The hand dynamometer's handle is adjustable with five positions to accommodate any hand size.

Full size right hand with cutaway views to reveal the effects of rheumatoid arthritis on ligaments, flexor and extensor tendons, muscle, cartilage, bones, synovial membrane, and joint spaces.

Quickly draw attention to emergency equipment.

A unique manufacturing process makes these models exceptionally lifelike. All feature a durable, yet flexible, rubberized material applied over molded plastic bone structures allowing for flexion and extension, inner and outer rotation, adduction and abduction, and other realistic movements of the joints.

Used to investigate wavelength in air.

Play sand provides tactile and sensory stimulation necessary for the development of a child's imagination, hand-eye coordination, and fine motor skills such as shoulder stability, forearm rotation, wrist control, and hand strength. Play sand also encourages creativity, visualization and social interaction.
