Ice Makers
Equipment designed to make aqueous and dry ice; products may be handheld, benchtop, or floor models. Includes water filters and filtration systems for ice makers.
Ice makers are used to produce ice from water or “dry ice” from liquid nitrogen. Most laboratories have access to an ice machine, since ice is used to keep samples and reagents cold during experiments or other lab work.
Ice makers are typically large floor-model units that are plumbed directly to a water source. However, smaller capacity benchtop and undercounter units are also available. Ice makers may contain replaceable air and water filters or cartridges and may have antimicrobial features that help to maintain water and ice quality.
Ice makers vary in size based on the amount of ice they can produce and store. They also vary based on the type or shape of ice produced, including:
- Cubes
- Flakes
- Nuggets/pearl-shaped
Some ice makers dispense water and ice; others have large covered bins from which one must scoop or otherwise transfer the ice into a secondary container.
Ice-making may be continuous until a certain threshold is reached, while other ice makers can be programmed to meet fluctuating demands and high- and low-use periods. Most ice makers run on a regular current, much like refrigerators or freezers. They usually vent toward the front, which allows them to be placed in smaller or enclosed areas.
Laboratory dry ice makers, produce small quantities of dry ice, usually about a 16 oz. (454 g) block at a time. One block typically takes less than five minutes to form. Production requires a tank of liquid carbon dioxide with a dip tube; a 50-pound tank can produce anywhere from eight to 16 blocks of dry ice. Other versions that produce dry ice as flakes or “snow” are also available.
Electron Microscopy Sciences MAC 42 Universal Block Auger Standards, 25 mm
MAC has developed multi-element blocks of reference materials suitable for the compilation of a reference library of Auger sensitivity factors when used with the Auger Electron Microscopy (AES). A carefully selected range of elements or compounds will enable the surface analyst to compile a valuable reference library of spectra. A Faraday Cup, for the accurate measurement of specimen current, is available as an option.
Multi-element blocks containing up to 50 reference materials can be made to suit the configuration of the most instrument. The reference material each has an exposed area about 2 square mm and are polished to a 1/4 micron diamond finish. The block of reference material is made from AISI 304 grade austenitic.
All blocks are supplied with certificates of analysis.

Electron Microscopy Sciences Frigimat Dry Ice Maker (Us Model)
The Frigimat Dry Ice Maker eliminates the need to buy large quantities of dry ice when only a few blocks are needed. It employs the Joule-Thomson effect to produce a solid 454 gm (16 oz.) block of dry ice in one to two minutes. A brass relief valve safely vents excess gas. Removing the dry ice block requires just 30 seconds. Each 50 lb. cylinder of liquid CO2 will make 8 to 9 blocks of dry ice, each measuring 8.5cm (3 1/8") x 11cm (4 3/8").
The unit is made from epoxy-coated steel with an aluminum ice chamber and brass valves with four non-skid rubber feet. Shipping weight: 5.5kg (12 lbs) and includes a 1.8m (6 ft) nickel-plated copper connecting tube with standard GCA 320 (0.830" – 14) thread couplings for easy attachment to an LCO2 cylinder.
