1. Specifications

Tube Holder Configurations:

The fixed-angle rotor that came with your Model 614B is capable of spinning test tubes

up to 17mm x 125mm. Use the following chart and drawing to determine which tube

holder and cushion combination should be used with your application.

DIRECTIONS:

Compare the tube to be spun with the four boxes shown below.

Find the box that most closely matches the tube's length. NOTE: The

tube length with its stopper or cap must be shorter then the chosen

box or the tube will not fit properly in the tube holder.

Match the letter from the chosen box with one of the configurations shown.

For Example: A tube is found to be as long as box B. Accordingly, we can

use a 125 mm tube holder with a 1525 cushion or a 100mm tube holder

with no cushion, (configuration B).

* This part is available as an accessory. Contact The Drucker Company for assistance.

Care and Preventative Maintenance:

With proper care and maintenance your centrifuge will provide years of

laboratory service.

For proper care, the following steps should be taken:

Provide Adequate Ventilation:

in ambient air through the air intake cover on the top of the lid and exhausts

this air in the rear of the base. The centrifuge should be placed on a hard

smooth surface for good air circulation.

Always Spin Balanced Loads:

a balanced load. The Model 614B has a unique counter balanced motor

mounting design which, along with its rubber suction feet, produces

excellent vibration dampening. However, out–of–balance loads may break

glass test tubes and may produce unsatisfactory separation results.

Proper load balancing will improve sample separation and extend the life of

the centrifuge. Refer to page 4 on balanced loads for additional information

on balancing the load.

Keep the Tube Holders Clean:

of your laboratory to properly clean up and/or dispose of materials in the event

that a substance known to be potentially toxic, radioactive or contaminated

with a pathogenic microorganism is spilt in or on the centrifuge. Small

100mm

glass fragments left in the tube holder after a tube breakage may adhere to

Tube

the next test tube inserted in that holder. When this tube is handled, these

Holder

fragments may puncture protective gloves and lacerate the operator's

fingers or hand. Remaining fragments may provide stress points on

subsequent tubes and result in additional breakage. If a tube breakage

occurs, carefully remove the tube holder. Properly dispose of the sample

and tube fragments and thoroughly clean both the inside and outside of the

tube holder. Insert a new tube cushion (if necessary) and replace the tube

holder in the rotor.

Motor and Electrical Maintenance:

A/C motor. It should not need servicig for the life of the centrifuge. The electrical

components are selected for high reliability and should not need service.

Keep the Rotor Chamber Clean:

tube breakage, (refer to the note in #3), it may be necessary to remove the

rotor and clean the rotor chamber. Follow the instructions on page 5 to

remove and re–install the rotor.

CAUTION: Before cleaning, always unplug the line cord from the electrical

outlet to eliminate the risk of electric shock.

The rotor chamber, rotor and accessories should be thoroughly cleaned

using either isopropyl alcohol, soap and water, or bleach. The use of Fully/

Partially Halogenated Hydrocarbons, Ketones, Esters and all other

chemicals not prescribed by the manufacturer may cause damage to the

with

rotor and tube holders and should not be used. Apply cleaning solutions

with a towel or cloth.

Do not submerge the centrifuge in water or other cleaning solutions

as this will cause damage and void your warranty!

For cooling purposes, the centrifuge draws
