Overview

Overview

The 402 Dilutor-Dispenser, is used to transfer liquids

between vials according to user defined protocols

(Methods). You program the 402 Dilutor-Dispenser

via the keypad, which includes an LCD screen, for

communication purposes.

You may store a total of 99 linkable Methods using

the keypad. Each Method consists of one or more of

the following tasks: Dilute, Dispense, Mix, Pipette,

and Rinse. In addition three functions for direct

manipulation are available: Priming, Titration,

Volume Measurement.

Gilson’s 402 Dilutor-Dispenser is available in two

configurations: Single-syringe, or Dual-syringe.

The 402 Dilutor-Dispenser is very versatile; it may

be fitted with seven sizes of syringe. The standard

402 Dilutor-Dispenser is equipped with a hand-

held probe for aspirating and dispensing liquids.

Optionally, the probe may be fitted with disposable

tips (Gilson Diamond® Tips, D200 and D1000).

This versatility means that your 402 Dilutor-Dispenser

may be used for a wide variety of applications

including the chemical field where the ability to

handle large volumes or high dilution ratios may be

appreciated, and the biological field where small

volumes and protection against cross-contamination

are important (see Autoclavability, page 6-5).

It can even be used with corrosive liquids (see

Chemical Compatibility, Appendix B).

Refer to Appendix A for lists of the standard

equipment, additional accessories and spare parts.

The 402 DD is supplied with a tubing kit for con-

necting to a solvent reservoir. Syringes are not

included in the standard equipment; you should

order syringe(s) appropriate to your Method (volume,

systematic error and flow rate requirements; refer to

Appendix C). Also, a Tee junction kit (not includ-

ing the syringe) is available for upgrading a Single-

syringe Dilutor-Dispenser to the Dual-syringe version.
