The Dade DAC II 

• fully automatic
• multi purpose
• cell washing
• immunohematology
• cell re-suspension
• multi cycle capable

The four basic assemblies or components that comprise the mechanical portion of the instrument  are as follows: 

A. Centrifuge inner bowl - The centrifuge inner bowl houses the centrifuge rotor with 12-tube carrier. Access to these components is gained by opening the centrifuge top cover. The inner bowl is easily removed for cleaning. The saline dispensing adapter located on the top and inside of the centrifuge cover is connected to the saline pump by the saline output tubing.

Tubing.  The saline drain outlet is located at the rear of the centrifuge bowl and extends out of the rear of the instrument. An overflow drain is located just above the normal drain fitting. 

B. Centrifuge rotor - The centrifuge rotor has a capacity of 12 test tubes of either 10 x 75 mm or 12 x 75 mm size. All load-bearing components are manufactured from high grade, corrosion-resistant stainless steel. The rotor may be removed from the instrument by grasping the upper collar of the rotor and lifting. The centrifuge rotor can be placed either on a bench top or in a water bath, as the bottoms of the tube carriers act as supports.

C. Saline / Buffer Pump

D. Control panel - The control panel (also referred to as the operator’s panel or front panel) is equipped with a vacuum fluorescent alphanumeric readout display of RPM functions and time which allows the operator to continually monitor the status of instrument operation. All panel switches are the tactile type, activated by applying finger pressure to the embossed panel surface. A “rocker” power switch is mounted through the front panel.

Dade DAC II  automatic centrifuge also know as the Dade DAC II automatic cell washer. 

The Dade automatic centrifuge is a laboratory bench-top multipurpose instrument to perform cell washing and immunohematology procedures including cell re-suspension. This extremely reliable, robust instrument provides fast wash cycle capability.  It is easily programmable to perform 1, 2, 3, 4, or five wash cycles per test sequence. 

Each cycle consists of pro­grammed saline introduction and subsequent decanting during centrifugal rotation. The system provides a saline monitoring feature to warn the operator when saline is not being delivered. The centrifuge incorporates variable spin times for several different types of centrifuge operation. Decant RPM is operator adjustable to give more than 0.1 mL residuals if desired. 

An agitation cycle resuspends cells for approximately 5 seconds and then spins the celIs for 20 seconds before completion of the cycle. The agitate time, as well as spin after agitate time, is operator-programmable. The front control panel  contains a vacuum fluorescent display of RPM functions and time which allows the operator to continually monitor the status of instrument operation.

Either l0 x 75mm or 12 x 75mm glass test tubes can be used in the rotor. Use of a 10 mm adapter in each tube carrier is required for 10 x 75 mm test tubes

Can't afford a DAC?  The Immufuge is the manual alternative centrifuge for cell washing and decanting procedures.  The Immufuge is discontinued and obsolete but replaced by the EBA 21 centrifuge
