This pre-assembled DC motor is designed for students to learn about electromagnetic forces. The open structure resembles the diagram found in many textbooks. The polarity of the magnets can be reversed to change the direction of rotation. The motor can also be used with a rheostat to observe the change of speed with the change of current. The DC motor can stand vertically or horizontally and operates on a 1.5V battery (not included). It comes in a sturdy plastic storage case with a student activity manual Shipping weight: 11.45 oz., dimensions: 5.5" x 4.5" x 2.5".
Operating on 1.5 to 6 V DC, this electromagnet lifts up to 3.5kg. A current direction indicator is included for the study of the magnetic field. Shipping weight: 1.0 Lbs., dimensions: 6" x 5" x 2.5".
This unit will hold up to 18 thermometers. Sturdy aluminum construction with stove enamel finish. Bottom surface is rubber foam lined to protect thermometer bulbs. This is a must for every lab to hold and store thermometers.
• Cargille Immersion oils meet ISO standards for performance
• Available in 1/4 oz bottles
• Types A and B are used for most fluorescent microscopy applications, type NVH.
Cargille Immersion Oil is required for high magnification and to obtain sharp images with clear resolution. These Immersion oils meet ISO standards for quality. Type A (low viscosity) and Type B (high viscosity) are used for normal microscopy applications with viscosities from 150-1250 (centistokes). The greater the gap between cover glass and objective, or condenser and slide, the more desirable high viscosity becomes. Type A and B are both used for most fluorescent microscopy applications, but Type A has a lower viscosity, which reduces any tendency to trap air causing image degradation and is easier to clean up.
