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.
