Laboratory Centrifuge

Description:

Intended Use:

The Drucker model 614 is a low-cost, high-performance laboratory centrifuge designed for
the separation of laboratory fluid samples.

Versions of the Model 614 include:

Given specifications are for the black test tube holders designed for 15ml,
(16mm x 125mm), test tubes. The use of different holders and/or cushions
will slightly alter the top speed and RCF.

Supplied Equipment:

The following items are supplied with each model 614 centrifuge:

1. One (1) six-place, fixed angle, polycarbonate rotor.

2. One (1) operator’s manual

3. One or more of the following based on your accessory package:
Six (6) 125mm test tube holders, Black
Six (6) 100mm test tube holders, Red
Six (6) 75mm test tube holders, Green
Six (6) 1525 test tube cushions
Six (6) 9150 test tube cushions

Features:

Important features of the Model 614 centrifuge include the following:

614B: 3,150 RPM* (1,200 RCF) with a lid safety switch
614L: 3,150 RPM* (1,200 RCF) with a lid safety interlock system
614U: 1,700 RPM* (350 RCF) with a lid safety switch
614UL: 1,700 RPM* (350 RCF) with a lid safety interlock system
614V: 0-3,150 RPM* (0 to 1,200 RCF) with a lid safety switch
614VL: 0-3,150 RPM* (0 to 1,200 RCF) with a lid safety interlock system

* Nominal speed with a line voltage of 115 Volts at 60 Hz, +/- 100 RPM

• Conforms to UL STD 3101-1 and Certified to CAN/CSA STD C22.2 NO.

1010.1, (Models 614B, 614L, 614V, 614VL Only), ETL LISTED.

• Lid safety switch that cuts power to the motor if the lid is opened during

operation

• The model 614L, 614VL and 614UL have a “0” RPM lid safety interlock

system that prevents the lid from being opened until the rotating head reaches
approximately “0” RPM.

• Quiet Operation

• Brushless AC motor

• Two part molded inner housing of flame retardant polymer for superior

strength and sound absorption

• Cool-Flow air flow design that prevents overheating of samples

• Heavy gauge welded steel cabinet construction for safety and durability

• Clear lid for safe observation of samples and optical calibration of speed.

• Optional 8-place rotor

• Timed operation from 1 to 30 minutes

• Variable speed (Model 614V/VL only)

Installation and Operation:

Performance / Calibration:*

It is recommended that your Model 614 centrifuge be calibrated every 6 months.
The max speed of a 614B, L, V or VL should fall between 3050 and 3250 RPM* when
unloaded; this will give a separation force of 1120 - 1280 xg*. The max speed of a
614U or UL should fall between 1600 and 1800 RPM* when unloaded; producing a
separation force of 310 - 390 xg*. A photo tachometer is suggested to determine RPM.
If your centrifuge fails to operate within its prescribed range, contact your authorized
dealer or The Drucker Company.

* Given specifications are for the black test tube holders designed for 15ml, (16mm x
125mm), test tubes. The use of different holders and/or cushions will slightly alter the
top speed and RCF.

Environmental Conditions: The 614 centrifuge is not intended for outside use or

for use in extreme environmental conditions. Any use other than the manufacturer’s
suggested usage may impair the protection provided by the unit.

External Packaging and Inspection: Carefully examine the centrifuge and

document any damage that can be attributed to mishandling. A signed inspection report
should be furnished by the shipping company.

Note: The Drucker Company is Not Responsible for transit damage.

Setup Procedure: Unpack the centrifuge and inspect for obvious damage; place the

centrifuge on a hard, stable surface. Note: A bench top clearance height of 23 inches
(min.) is required to open the centrifuge lid.

Note: Failure to provide adequate space for ventilation can cause damage to the
samples plus overheating and premature failure of the centrifuge.

1. Unlatch and open the lid; remove any protective shipping material,
literature, tube cushion packages, etc., that may have been shipped
inside the centrifuge.

2. Spin the rotor by hand; check for free and level rotation. If the rotor
spins evenly, continue on to step 3. If the rotor does not turn freely or
there seems to be an obstruction, call your authorized dealer or
The Drucker Company before proceeding.

3. Close and latch the lid. Verify that the timer is "OFF". Plug the line
cord into an approved electrical outlet. Be sure the outlet is always
within reach as the line cord is the means of emergency disconnection.

4.

Turn power on to the unit by setting the time to (5) minutes.

NOTE: Model 614V/VL : Turn the speed to 3,050 RPM.

The rotor should start spinning smoothly with no excessive noise.

5. Listen to the sound of the centrifuge; a smooth whirring sound should be
heard. If there are any loud and unusual sounds, stop the centrifuge
immediately. Do not proceed! Call your Authorized Dealer or The
Drucker Company.
