General information about the Dry Block Thermostat

In order to carry out kinetics tests more efficiently in the laboratory, it is necessary to preheat the samples before measurement. In addition, the reagents must also be kept at incubation temperature during a series of measurements. For this purpose, a small and handy dry block thermostat was developed as a stand-alone system in addition to the Diaglobal Photometers.

The features in detail are:

• Temperature unit of 37 °C with an accuracy of ± 0.2 °C
• 12 positions for round cuvettes
• Indication of temperature control by LED
•  Heating up in 5 minutes per cuvette filled with 1000 μL
• Power supply: 12 VDC / 15 VA
• AC-Adapter: 110 – 240 VAC 50/60 Hz

Delivery and Installation

Delivery
After carefully unpacking the device, check whether it is in perfect condition.
Also, check if it is complete according to the delivery note. The box contains the following items: Dry Block Thermostat and AC-Adapter

The packaging materials must be stored carefully in case an item needs to be returned. Notify your dealer immediately if any defects are found.
Installation
Connect the AC-Adapter to the mains.
The operating voltage range is between 110 VAC and 240 VAC at 50/60 Hz.
Plug the connector into the socket on the backside of the Dry Block Thermostat.
The Dry Block Thermostat DZ 003 is switched on with the red switch on the front of the device.
After a few seconds, the green LED flashes. The red LED shows a continuous light.

Operating Elements

Operation

After switching on the Dry Block Thermostat DZ 003, the device heats up to a temperature of 37 °C.
The device needs about 20 minutes to heat up.
After the heat-up time, the GREEN LED shows a continuous light.
In this state, the system is ready for use.
The status of the device is shown by two LEDs (Light Emitting Diode):

GREEN LED (used for stability check)

• The LED is flashing: The temperature is not stable.
• The LED lights continuously: The temperature is stable.

RED LED (used for heating power)

• The LED is flashing: The heating is switched on and off.
• The LED lights continuously: The heating is switched on during warm-up.

Maintenance

This chapter provides necessary information concerning general maintenance by the user.
If fault-free operation of the device cannot be achieved, customer service should be contacted. Repairs to the device may only be carried out by authorised specialist staff. Unauthorised repairs can endanger the operator and also invalidate the warranty.

9.1 Cleaning Instructions
Liquid waste is potentially biohazardous. Always wear gloves when handling these materials. Do not touch any parts of the device other than those specified for use. Consult the laboratory protocol regarding the handling of biohazardous materials.
Take care that no liquid enters the device! There is no protection against penetrating liquids (Code IP X0).
Commercially available decontaminating solutions commonly used in clinical chemistry laboratories, such as Mikrozid® AF Liquid, Bacillol® plus, 3 % Kohrsolin® or similar, are recommended for cleaning the device and the surface.
Before cleaning the unit with a soft cloth and the decontaminating solution, it must be switched off and the electrical power supply must be disconnected.

9.2 Adjustment and Calibration
The Dry Block Thermostat is adjusted and calibrated at the factory on delivery; adjustment by the customer is neither necessary nor possible.
