Introduction

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

402Dilutor-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.
