Ultra, High, Low Speed and Micro, & Refrigerated Centrifuges’

A centrifuge is a machine with a rapidly rotating container that applies centrifugal force to its contents, typically to separate fluids of different densities or liquids from solids.

A spectrophotometer is an apparatus for measuring the intensity of light in a part of the spectrum, especially as transmitted or emitted by particular substances.

Many older spectrophotometers must be calibrated by a procedure known as “zeroing.” The absorbency of a reference substance is set as a baseline value, so the absorbencies of all other substances are recorded relative to the initial “zeroed” substance. The spectrophotometer then displays % absorbency (the amount of light absorbed relative to the initial substance).

Liquid Scintillation Counters

Rocky Mountain SIMS services, maintains, & repairs Liquid Scintillation Counters

Although the liquid scintillation counter is a sophisticated laboratory counting system used to quantify the activity of particulate emitting (ß and a) radioactive samples, it can also detect the auger electrons emitted from 51Cr and 125I samples.

Newer machines may use 96-well plates with individual filters in each well. Many counters have two photomultiplier tubes connected in a coincidence circuit. The coincidence circuit assures that genuine light pulses, which reach both photomultiplier tubes, are counted, while spurious pulses (due to line noise, for example), which would only affect one of the tubes, are ignored.

Shakers, Stirrers, & Baths

Rocky Mountain SIMS services, maintains, & repairs Shakers, Magnetic Stirrers, & Baths:

A shaker is a device used in chemistry and biology laboratories to stir liquids.

A typical shaker has a table board that oscillates horizontally, powered by an electric motor. The liquids to be stirred are held in beakers, jars, or Erlenmeyer flasks that are placed over the table; or, sometimes, in test tubes or vials that are nested into holes in the plate. Orbital shakers also exist, that shake the vessel in a circular fashion.

A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (also called “flea”) immersed in a liquid to spin very quickly, thus stirring it.

They are preferred over gear-driven motorized stirrers because they are quieter, more efficient, and have no moving external parts to break or wear out (other than the simple bar magnet itself). Because of its small size, a stirring bar is more easily cleaned and sterilized than other stirring devices.

There are four types of Laboratory Baths:

Cooling bath: a laboratory device that lowers the temperature of the bath or improves heat conduction
Heated bath: a laboratory device that raises the temperature of the bath to enhance a chemical reaction
Laboratory water bath: a laboratory device that maintains the temperature of the bath
Oil bath: a laboratory device that uses an oil to regulate the temperature of a sample


Rocky Mountain SIMS services, maintains repairs Ovens:

Laboratory Ovens are used for high-forced volume thermal convection applications. These ovens generally provide uniform temperatures throughout. Applications for laboratory ovens can be for annealing, die-bond curing, drying, Polyimide baking, sterilizing, and other industrial laboratory functions.


Rocky Mountain SIMS services, maintains, & repairs Incubators:

An incubator is a device used to grow and maintain microbiological cultures or cell cultures. The incubator maintains optimal temperature, humidity and other conditions such as the carbon dioxide (CO2) and oxygen content of the atmosphere inside.

The simplest incubators are insulated boxes with an adjustable heater, typically going up to 60 to 65 °C (140 to 150 °F), though some can go slightly higher (generally to no more than 100 °C). More elaborate incubators can also include the ability to lower the temperature (via refrigeration), or the ability to control humidity or CO2 levels.


Rocky Mountain SIMS services, maintains, & repairs Lyophilizers:

Lyophilization is a dehydration process typically used to preserve a perishable material or make the material more convenient for transport. Freeze-drying works by freezing the material and then reducing the surrounding pressure to allow the frozen water in the material to sublimate directly from the solid phase to the gas phase.

There are essentially three categories of Lyophilizer:

  • the manifold lyophilizer

  • the rotary lyophilizer

  • and the tray style lyophilizer
