Lab cooling equipment, such as chillers, refrigeration units, and cryogenic coolers, is essential for maintaining precise low temperatures during experiments. These tools help in controlling thermal reactions, preserving samples, and supporting processes like freezing or cooling chemicals and biological materials.
Water testing equipment includes devices like pH meters, turbidity meters, and water quality testers. These tools are used to measure various parameters such as pH, turbidity, and chemical contaminants, ensuring water safety and compliance with environmental standards.
Blood testing equipment includes devices like blood glucose meters, centrifuges, hematology analyzers, and microscopes. These tools are used to analyze blood samples for various parameters, aiding in the diagnosis and monitoring of health conditions.
Lab heating equipment, such as hot plates, Bunsen burners, and heating mantles, is essential for precise temperature control in scientific experiments. These tools ensure safe and efficient heating of substances, supporting various processes like chemical reactions and sample preparation.
177mm diameter circle, Allows readings to 30 seconds of arc. This instrument whilst robust enough for individual student use is  also  intended  for  more  advanced  work.  The  general  finish  of  the  apparatus is similar to that of the intermediate model. The instrument  is  mounted  on  a  baseboard,  which  fits  into  a  polished  hardwood  case.
Scale:  The  177mm  diameter  circle  is  fixed,  and  the  table  and  telescope movements are completely independent of each  other.  Both  movements  can  be  read  to  30  seconds  of  arc  by  means  of  the  double-ended  vernier.  Both rotations have fine adjustment screws, and the release of  a  clamping  screw  enables  coarse  adjustment  to  be  made  by  hand.
Collimator:  Mounted on the fixed pillar and fitted with 178mm  focus  achromatic  objective,  32mm  clear  aperture.  A  unilaterally  adjustable slit,  6mm  long  is  also  fitted.
Telescope:  Mounted on the moveable pillar and fitted with 178mm  focus  achromatic objective, 32mm clear aperture. Also fitted is a  15�?  Ramsden eyepiece and a cross-line graticule. Both the telescope and collimator have rack and pinion focusing. Means are provided  for  leveling  the  axes  of  both  optical  units  and  for  squaring  them  to  the  axis of  rotation.
Prism  Table:  The  table  is  marked  with  lines  to  assist  placing  the  prism with respect to the table leveling screws, and has interchangeable clamping  units  for  the  prism  and  a  diffraction  grating.
Standard Accessories Supplied:  1 Dense Flint Glass prism, 1 Prism clamp,  1  Diffraction  grating  holder,  1  Watchmaker\'s  eyeglass  ,  1  Tommy  bar / L Key for adjusting the optical axis of tubes, 1 Polished hardwood case.
These are collapsible pocket magnifiers. The optical system is a single element, glass Double Convex Lens. The housing is made of machined, black high grade plastic for a high finish look. These magnifier fold flat to fit in your pocket. Scales are etched on the inner faces of the viewers base
This magnifier is mounted on a comfortable head band. Since both eyes are used it provides 3D vision enabling fine manual co-ordination. Ideal for any kind of detail work where both hands are required to be free to attend the work. Available in five models with different magnifications.
