CHROMBOX HPLC fittings kit

Analytical HPLC pump from the previous, Series 1100 Cecil HPLC range, still nice at half the price.

This four channel degasser is very efficient at degassing mobile phase, as and when required.

The FE280 is a basic, simple, routine instrument which allows conductivity to be measured across 4 ranges with full temperature compensation. The temperature coefficient is set at 2%/oC. Ideal for standard applications such as water quality measurements or spot checks on on-line equipment.

The automatic FE287 is much more than a conductivity meter. The related mesurement of resistivity and total dissolved solids are of course possible, but in addition, salinity and concentration measurements can be performed, making the meter one of the most flexible available. Six ranges of conductivity are possible and are selected automatically. Readings are displayed in multiples of S/cm or S/m.

The BA380 is a basic, bench conductivity meter. It measures conductivity only, using automatic temperature compensation and, despite its simplicity, affords the user measurements accurate to plus or minus 1%. The meter is calibrated to one point using traditional manual controls and a conductivity standard. Once the calibration is set, the user may select the appropriate range for the sample and read conductivity value directl…

The GP383 is a general purpose meter. Conductivity and temperature measurements can both be achieved, temperature compensation being either manual or automatic. Once calibrated against a standard solution, the cell constant can then be inspected. Know cell constants may be entered directly. The GP383 has a recorder output for use with recorders or dataloggers.

Apart from conductivity, the user is able to measure: resistivity; total dissolved solids; salinity and temperature. These modes may all be accessed without the need to change cell or calibration and are all temperature compensated. One of the most common application areas of conductivity mesurement is concentration control. The RE388TX may be calibrated in concentration units and a sample concentration then read directly from…

The DR359TX is an advanced, ion concentration meter which automatically calculates the relationship between two or more concentration standards and stores this in memory allowing unknowns to be read directly. Anion/cation recognition is automatic and up to 5 calibration points may be entered, enabling the user to cover a wide dynamic measurement range with just one calibration. The DR359TX also provides full pH facilities incl…

Single & double end fittings in stainless steel & PEEK collared connectors

The Direct Connection UNIGUARD allows the guard cartridge outlet to be directly placed against the analytical column inlet frit. Product detail: We recommend all analytical columns are protected by a guard cartridge, which is replaced on a regular basis. The ID of the analytical column determines the correct ID for the guard cartridge. We offer 10x1, 10x2, 10x3, 10x4mm guard cartridges in all our stationary phases to ensur…

The Javelin guard design is a one-piece format that can be installed without wrenches and requires no holder, which allows quick and easy replacement. Product detail: We recommend all analytical columns are protected by a guard column or cartridge, which is replaced on a regular basis. The ID of the analytical column determines the correct ID for the guard, so we offer 1.0, 2.1, 3.0 and 4.0 diameter Javelin guard columns in…
