Laboratory Instrumentation & Supplies

In the area of laboratory, Carl Stuart Ltd provide all sorts of solutions from tablet and API testing through to weighing, filtration and stirring and shaking. The pharmaceutical industry has many well know and experienced manufacturer’s who work closely with Carl Stuart Ltd to make sure you get the best from the experts in the laboratory field.

Here is a handful of those manufacturer’s who work along side Carl Stuart Ltd to ensure you get the best.

Sotax are well known for Tablet Testing. Tablet Testing consist of Dissolution Testing, Physical Testing and Content Testing. Under Dissolution Testing the strong areas are Fully Automated Systems, Manual Systems, Media Preparation Station (MPS), Semi Automated Systems undefined and USP 4 Flow Through Systems. Where as Physical Testing consists of Disintigration, Friability, Hardness, Powder Flow and Tap Density. Carl Stuart Ltd are the main distributor and technical support center for Sotax within Ireland.

When it comes to sample preparation in labs, Hamilton diluters allow rapid and accurate preparation of liquids at the microlitre level reducing the need for large quantities of glassware.

Whether you have a larger or small lab, adequate volumes of water quality must be available at all times. The TKA series of water purifiers offer laboratories sufficient water at quality as high as 18megaohms.

Temperature control is a common requirement fulfilled by the extensive Julabo range of water baths and recirculators for both cooling and heating.

Leibherr fridges and freezers are suitable for storage of precious samples at temperatures down to minus 35 degrees Celsius.

Heidolph and IKA provide stirring and shaking, mixing and heating equipment which now makes it possible to heat, stir and shake simultaneously.

One main essential in Laboratories is weighing. Manufacturers such as; Kern, Sartorius and Mettler Toledo provide the accuracy combined with ease of use when weighing in a Lab.

Filtration and separation both at the macro and micro levels can be achieved utilizing Retsch sieves for standard separations and disposable Whatman filters at the submicronic (0.2 and 0.45 micron) level.

Health and Safety is extremely important when handling any materials in a laboratory. Clean air laminar flow cabinets and extraction cabinets are amongst the best available.

Elma ultrasonic baths have many uses from cleaning to sample particle dispersion.

Carl Stuart Ltd, offer a wide range of Miele industrial washers designed specifically for cleaning glassware and other lab items.

Chromatography

The supply of consumables for Gas Chromatography (GC) and High Performance Liquid Chromatography (HPLC) is of vital importance to the Chromatographer. Without supplies such as vials, caps, septa, syringes, deuterium lamps, syringes and inlets, instrumentation cannot run.

On of the main leaders in this field is Agilent Technologies who have a full line of columns and consumables. The J & W brand which consists of HPLC packing materials such as the Zorbax range and GC columns, offer specialist accessories such as their flip top system and gas flow meters for GC.

Chromacol is one of the longest manufacturer’s of vials, caps and seals for chromatography. Their range of vials will fit autosampler trays from all the major manufacturers including Thermo, Waters, Agilent, Shimadzu, CTC, Merck and many others

The Hamilton brand is identical because of their first product the microlitre syringe for injecting samples. Hamilton also offers a full line of GC columns, inlets and septa plus HPLC columns for nion, Cation and Ion exclusion chromatography .

Inertsil HPLC Columns which are manufactured by GL Sciences well know for being rugged and durable. They operate at lower back pressures than other brands like; Chiral who also have a range of HPLC Columns for analysis and separation.

The Paker range can produce gases at the quality required for all GC, GC-MIS LC-MIS and ICP-MS applications, as high purity gas supply is fundamental to gas and liquid chromatography.

Gases used in a lab must meet the required purity at all times. SGT super-clean gas filters ensure these requirements are meet GC and GC-MS

Whatman filters ensure when injecting samples for analysis by HPLC that no foreign particles are accidently loaded on to the column thus shorting its life.

At Carl Stuart Ltd we can scale your application from micro bore to preparative capacity. We offer method validation, development kits, and method specific columns. In addition, application support including chromatogram libraries, USP and EP methodologies, column and detector test mixtures and checkout samples are also available.

Environmental / Microbiology

When carrying out every day environmental analysis there are required measurements to follow; Conductivity, Dissolved oxygen and pH as well as Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). WTW have lab instruments for all field and on-line monitoring and analysis.

Personnel safety is of major concern in the lab. Increasing emphasis is now being focused on biological safety cabinets meeting either class 1, 2, 3 or 4 depending upon the materials being used in a lab. CleanAir manufacture these quality instruments.

Of course no environmental laboratory would be able to function without suitable microscopes. Carl Stuart Ltd offer a full range including Biological compound, Epi Fluorescence, Stereo microscopes and more basic mono- and binocular microscopes. Within this product line we also supply polarimeters and refractometers.

Calibration and Service

In the modern lab the functioning of instrumentation is of paramount importance particularly in critical areas such as pharmaceutical and healthcare.

Installation Qualification (IQ), Operating Qualification (OQ) and Performance Qualification (PQ) are verification procedures that confirm instrumentation is working in accordance with the manufacturers specifications.

At Carl Stuart Ltd we are able to offer the complete service to the lab utilizing our Total Lab Solutions package whereby all instrumentation can be maintained and serviced by us, thus reducing the amount of administration for the analyst, allowing him or her more time to get on with the actual analysis.
