Sample Vials:       Nominal 40ml capacity, single hole cap with Teflon faced silicone septum, per EPA specifications. 3-3/4”(905cm) high,1-1/16” O.D.,24 mm ID cap for water sampling.

Trays:             Accepts vial two 35 position trays or one optional 70 position vial cooling tray.

Vial Cooling:   Optional vial cooling tray to cool vials to 4℃ as per EPA specifications.(Requires an external recirculating cooling bath)

Bath Connection:    Inlet and outlet hose connections require 1/4” I.D. tubing. Bath must have a minimum cooling capacity of 300 watts.

Sample Types:      Drinking water and wastewater (water samples containing sediment levels of up to 15 mm when measured from the bottom of an upright 40ml vial)

Sample Loop:       Interchangeable loops; 5 or 25ml volume, 1/8” O.D. coiled,

Standard Injection System:4-way valve, 2μL volume delivery

Internal Standard Accuracy:  2μL+/-10%

Internal Standard Consumption: 11μL at 0.02min Fill IS

                          16μL at 0.04min Fill IS

Electronic Control:  Concentrator control of optically isolated I/O

Instrument Control:  AQUATeK 70 is controllable with a PC running TekLink software in a Windows^TM environment. TekLink integrates control of the 3000 series Purge & Trap with the AQUATeK 70.

Method Storage:   Up to 16 methods including pre-programmed methods.

Vial Sampling Device:  XYZ robot with stationary vial rack design capable of an accuracy of +/- l mm in XYZ dimensions and repeatability of +/- 0.25 min in XYZ dimensions.

High Temperature OptiRinse:  AQUATeK 70 uses dual internal reservoirs which heat the water to clean the entire sample pathway. (Includes sample loop, sample pathway, and glassware on the concentrator.)

Rinse Kits:         AQUATeK 70 requires either a rap rinse Kit or a reservoir kit. These do not add additional width so bench space used is not increased.

Sample Path:       1/8” O.D. Teflon® tubing

Valving:         Four 12VAC ,3 port solenoid valve One 115 VAC motor actuated 4-port valve
