1. Introduction

There are three versions of the Asymptote controlled rate freezer:

EF600-00: Stand alone freezer with no data logging capacity.

The EF600-00 is pre-loaded with a single default program for the

cryopreservation of human embryos (Lasalle et al., 1985). An alternative

program may be specified at the time of ordering.

EF600-01: Freezer with data logging to a dedicated PC (supplied by

Asymptote Ltd.).

The EF600-01 is pre-loaded with a single default program for the

cryopreservation of human embryos (Lasalle et al., 1985). An alternative

program may be specified at the time of ordering.

EF600-10: Freezer with data logging to a dedicated PC (supplied by

Asymptote Ltd.).

The EF600-10 is pre-loaded with six standard freezing programs (embryo,

oocyte, blastocyst, stem cell, spermatozoa linear program and spermatozoa

non-linear program), which the user selects in the supplied data logging

software. Additional programs, up to a total of 10, may be specified at the

time of ordering.

This manual includes operating instructions for all three versions. The following

optional extras may also be supplied with the EF600 series freezer:

Cryopen nucleating tool (EF-611)

Uninterruptible power supply (UPS) (EF-613)

Conversion kit to allow portability (EF-614)

Data logging software for upgrading the EF600-00 (EF-620) and EF600-01

(EF-621)

Software for programming linear temperature profiles (EF-622)

Software for programming non-linear temperature profiles (EF-023)

Operating instructions for these optional extras are given in Appendices 2 - 7.

1.1 Warning

It is essential that this instruction manual is read before using the EF600

freezer. Particular attention should be paid to the safety precautions

below.

1.2 Safety precautions

Operating the freezer

Temperatures down to -100ºC are reached within this equipment. Ensure that

protective gloves are worn when accessing the freezing plate, during and after

the freezing cycle, to avoid cold burns. Do not move the freezer whilst

operating as the baseplate will be hot.

Operating the cryopen nucleating tool

Read the instruction manual and safety instructions supplied with the cryopen

nucleating tool. Ensure that gloves are worn during use and never point the

cryopen towards the face.

Plate temperature

The plate temperature should never exceed 30ºC. If it does, turn the freezer

off immediately.

1.3 Maintenance

A service contract on the EF600 series freezers is available. Contact

[email protected] for full details. Please note that there are no user

serviceable parts within the EF600 and that breaking the security tags

invalidates any warranties.

2. Installing the Freezer Unit

2.1 Unpacking

Carefully unpack the Asymptote EF600 controlled rate freezer from its carton

and place upon a suitable bench. Only lift the freezer by placing hands

underneath the freezer; do not move the freezer by pressing on the casework.

Inspect the unit to ensure that no damage has occurred during transit. The

following items should be included in the carton:

EF600-00:

a) EF600 freezer unit and lid

b) Instruction manual – on CD

c) Power lead

EF600-01 and EF600-10:

a) EF600 freezer unit

b) Instruction manual – on CD

c) Power lead

d) Communications cable

e) Laptop computer with data logging software for either EF600-01 or

EF600-10 installed

f) CD back up of installed software

Optional extras, such as a cryopen nucleating tool and UPS, will have been

supplied with the EF600 freezer if ordered.

If the unit shows any sign of damage, or if any of the items listed above are

missing, please contact the supplier immediately.

2.2 Positioning the freezer

Ensure the freezer is positioned so that the vents at the side of the freezer unit

and the air outlet at the rear of the freezer unit are not blocked. Leave a

clearance of at least 200 mm.

2.3 Electrical connection

For normal connection to the mains, plug the power lead into the rear of the

freezer unit and connect to an appropriate single-phase mains supply. If an

UPS is being used please refer to Appendix 3. If operating as a portable unit

please read Appendix 5 before using the freezer.

2.4 Switching the freezer on

Tel: +44 1223 421161, Fax: +44 1223 421166, E-mail: info@asymptote.co.uk

Connect the communications lead (9-pin D-type male to female) between com

port 1 (the serial port) on the computer and the back of the freezer. Power-up

the freezer unit using the ON/OFF switch on the front panel of the unit (figure

2.4). The switch illuminates red when the power is switched on.

3. Starting Asymptote’s Data Logging Software (EF600-01,

EF600-10)

Tel: +44 1223 421161, Fax: +44 1223 421166, E-mail: info@asymptote.co.uk

Start the software by either double-clicking on the shortcut icon on your

desktop (figure 3) or by selecting ‘Asymptote Data Logger’ from the program

list in the start menu on your computer.

Figure 3 – Desktop shortcut icon

The program window will open. Initial values for the ‘Set Point

Temperature’, ‘Plate Temperature’ and ‘Stirling Voltage (V)’ will be

displayed as ‘999.00’; these will automatically update once communications

between the freezer and the computer have been established.

4. User Interface (EF600-01, EF600-10)

The current ‘Set Point Temperature’ of the freezer is displayed in red on the

left of the screen. This is the required temperature of the sample plate.

The current ‘Plate Temperature’ is displayed in blue in the centre of the

screen. This is the actual temperature of the sample plate.

The current ‘Stirling Voltage (V)’ is displayed in green on the right of the

screen. This is the output level of the Stirling Engine and is only provided for

diagnostic engineering purposes only.

The graph can show either the last minute of the cycle or the whole run.

Check ‘last minute’ or ‘whole run’ to switch between these features. The time

elapsed and the total run time of the cycle is displayed in the top left hand

corner of the user interface. The bottom of the user interface displays

information on the status of the cycle.
