WARNING Information displayed under this heading relates to the prevention of equipment and/or environmental damage. CAUTION Information displayed under this heading relates to correct handling or use of the equipment. Disregarding these instructions or cautions can lead to malfunctions or minor equipment damage.
  • Page 7 REGISTRATION In order for Oxford Cryosystems to be able to provide an efficient and effective service, you should register your system with us. The most convenient way to do this is by creating an account on Oxford Connect (connect.oxcryo.com) which has the added advantage of allowing you to monitor and control your Cryostream system remotely.
  • Page 8 SAFETY INFORMATION GENERAL SAFETY AND ENVIRONMENTAL USE The 1000 Series Cryostream unit (consisting of the Gas Supply Module and Coldhead), is designed to be operated within the following environmental conditions: • Environmental Temperature Range: 15°C to 35°C • Relative Humidity: 10 - 70% In addition to the above, please ensure the following safety conditions are followed: •...
  • Page 9 Cryosystems. Under no circumstances should the supplied Dewar vessel be sealed or pressurized in any way. Whilst the system can be used with a variety of unpressurised Dewar vessels, Oxford Cryosystems accepts no responsibility should there be any detriment to the performance when using alternative vessels, sourced through third parties or otherwise, and accepts no liability should there be any damage caused to the Cryostream system, third party systems or personnel.
  • Page 10 3.4 REFILLING DANGER Refilling of the Cryostream Dewar should only be carried out by someone trained in the handling of liquid nitrogen. 3.4.1 Points of Consideration when Refilling the Dewar Vessel • Ensure the operator has had appropriate training and is wearing the relevant Personal Protective Equipment (PPE) as specified during the training.
  • Page 11 Oxford Cryosystems has designed, built and supplied the system in good faith but the user installs and uses the system at their own risk. The user should only operate the system in ‘Automatic mode’ while someone is in attendance.

Use the Hex key (in the opposite direction) to tighten the two components together. For packing purposes, the Black Mounting Pin may be mounted backward in the Varibeam Nozzle Clamp.
  • Page 20 Fixing 3 Fixing 1 Fixing 2 Fixing 4 Figure 6.4 Varibeam base plate Figure 6.4 Schematic of varibeam base plate Prior to drilling mounting holes for installation, it is recommended to experiment with various positions first. This can be done by using a G-or C-clamp to temporarily fix the Varibeam to the tabletop. Ensure that the cabinet manufacturers guidelines are properly observed when considering any modifications for fixing bolts.
  • Page 21 The pivot block and translation slide have two sets of measurement indicators, which combined with knobs A…C, allow the user to perform fine adjustments in the position of the coldhead. The range of adjustment is shown in the table below. Translation (mm) Angle (degrees) Angular measurement scale.
  • Page 22 The crystal should be less than 8 mm from the end of the Cryostream nozzle (optimum distance is 5 mm) in the centre 2 mm of the gas stream; this will help to prevent icing. The Oxford Cryosystems Nozzle Alignment Tool is ideal for determining the correct position.
  • Page 23 6.4 STAGE TWO - HANDLING OF CRYOSTREAM COLDHEAD AND TRANSFER LINE Please ensure that; a) The rigid section of the Cryostream Transfer Line can be fed through a port in the cabinet or labyrinth (if applicable). DANGER Please ensure that any ports made in your cabinet adhere to your local Health and Safety laws and policies and have been approved by your local Health and Safety Officer and the original enclosure manufacturer.
  • Page 24 The purpose of the Dewar vessel is to hold the liquid nitrogen to be used by the Cryostream. The ES Dewar vessels supplied by Oxford Cryosystems have been designed specifically for use with the Cryostream. Other Dewars can be used with the Cryostream, however, Oxford Cryosystems does not take responsibility for other Dewar vessels or their suitability.
  • Page 25 Because the Cryostream applies the same gas pressure at the crystal as it does in the Dewar, it is safe to replenish the supply of liquid nitrogen to your Dewar at any time without any fluctuations in gas temperature. This can done manually or by using the Oxford Cryosystems automatic refilling system. NOTE Please ensure that the Dewar is at least ~20% full at all times.

  • Page 29 CRYOSTREAM NOZZLE ALIGNMENT The Nozzle Alignment Tool has been designed to allow the exact centring of a crystal sample in the nitrogen gas stream. Accurate alignment of the stream is vital to avoid ice formation, as it ensures that the crystal stays in the coldest part of the stream as it rotates.
  • Page 30 PROGRAMMING THE CRYOSTREAM 1000 SERIES CRYOSTREAM FINAL CHECKS BEFORE SWITCHING ON THE CRYOSTREAM • Ensure that all the tube and power connections are correctly made. • Ensure that there is liquid nitrogen in the Dewar and the Cryostream rigid transfer line is in the Dewar vessel.

  • Page 67 APPENDIX 4 REPAIRS AND RETURNS PROCEDURE To allow Oxford Cryosystems to offer fast and accurate technical support, please quote the Cryostream Serial Number with all technical issues. It is worth keeping a record of this number in a convenient place:...
  • Page 68 Returns procedure Do not return any equipment without contacting Oxford Cryosystems in advance. Use the following procedure to return ANY items for repair. 1. Contact Oxford Cryosystems (support@oxcryo.com) and obtain a Return Material Authorisation (RMA) number for the equipment which must then be written on each box being returned. Without this number Oxford Cryosystems may reject the consignment.
  • Page 69 All users are requested to read this safety sheet before handling the Cryostream. Oxford Cryosystems accept no responsibility for injury or damage caused by the mishandling of liquid or gaseous nitrogen.
  • Page 70 Symptoms of oxygen deprivation, such as increased pulse and rate of breathing, fatigue, and abnormal perceptions or responses, may be apparent at an oxygen concentration of 16%. Permanent brain damage or death may arise from breathing atmospheres containing less than 10% oxygen. Initial symptoms will include nausea, vomiting and gasping respiration.
  • Page 71 Where large spills of liquid nitrogen occur, a fog forms in the vicinity of the spill caused by the condensation of water vapour in the surrounding air. The fog, in addition to severely reducing visibility may contain oxygen concentrations appreciably lower than that of the air presenting a local asphyxiation hazard. Personnel protection Persons handling equipment in service with liquid nitrogen should wear protective face shields, loose fitting gauntlets and safety footwear.
  • Page 72 4. Frozen tissues are painless and appear waxy with a pallid yellowish colour. They become painful, swollen and very prone to infection when thawed. Therefore, do not re-warm rapidly if the accident occurs in the field and the patient cannot be transported to hospital immediately. Thawing may take from 15-60 minutes and should be continued until the blue, pale colour of the skin turns to pink or red.
  • Page 73 NITROGEN REFILL SYSTEM (AUTOFILL) INTRODUCTION Oxford Cryosystems has an optional autofill system which can be purchased with the Cryostream or later be retrofitted. The heart of the system consists of a capacitance based Liquid Level Sensor connected to the 1000 Series Gas Supply Module.

  • Page 77 • It is recommended that you start at the Self-pressurised Storage Vessel. You may find the system comes partly assembled from Oxford Cryosystems. • When assembling the Cryostream Dewar Neck Fitting for the Cryostream Dewar, it is important that the correct connection is fitted into the correct port.
  • Page 78 Figure A10 Schematic of autofill assembly WARNING It is very important that the Relief Cross with pressure relief valve, 24V solenoid valve and decanting valve assembly is fitted the right way up. The valves WILL NOT OPERATE CORRECTLY IF INSTALLED UPSIDE DOWN. Use the image above to determine the correct orientation.
