Manufacturer: Linkam / BTL (Biopharma Technology Ltd). Model: Lyostat 3 Freeze-Drying Microscope. Description:. BTL's freeze-drying microscopes, the Lyostat series, have been popular for many years due to their speed and precision in returning usable data. The latest in the series, the Lyostat3 has improved hardware and software and many options that offer increased reliability and flexibility while retaining the same functionality as the Lyostat. New features include:. • New Linkam Scientific 95 Series controller with better connectivity and precision control • New nitrogen pump for precise linear cooling rates • New design and soft blue LED illumination • Power ratings allow use at any voltage and frequency • New "LinkPad" touchscreen device for monitoring power levels in the field and easily checking firmware versions • Firmware upgrade via USB connection • Vacuum control module replaced with PC card style to minimize the number of power connections required • Increased data sampling rates and resolution to improve data precision. Lyostat3 Technical Specification:. Stage and Controller: · Working temperature from -196ºC to +350ºC. · Controlled heating and cooling rates · Programmable profile function allowing multiple ramp and hold steps · High purity silver heating/cooling block for good thermal conductivity. · 100 Ohm platinum resistor sensor for temperature monitoring/control (DIN Class A to 0. 1°C). · Vacuum tight sample chamber down to 10–3 mbar. · Port for direct measurement of chamber vacuum. · Optional vacuum control module. Nitrogen Cooling System: · Automatic twin pump cooling system including 2L Dewar and flexible insulated tubing. · Twin pumps for faster cooling. · Direct injection of coolant into the silver block. Software: · The software displays live stage temperature and pressure, active ramp information and allows the user complete control of the temperature programmer via an RS232 serial link to the PC. · Online plot information of temperature and pressure can be viewed, saved and exported to third party applications such as Excel. · A temperature profile consisting of multiple ramp and hold steps can be created in a simple on-screen data table. Imaging station with folding head for easy sample loading:· Fewer objectives than the compact microscope for clearer images· Polarizing lens with analyzer· Long working distance condenser· 100W halogen lamp light source· Power supply with variable light intensity adjustment· Köhler illumination. Alternative compound microscope comprising:· Quality robust frame· Plan 10x objectives· C-mount video port 1. 0x· 18mm wide field eyepieces· Köhler illumination· Trinocular headItems supplied:. - Linkam LinkPad controller- Linkam LNP95 - Linkam T95-PE- Olympus microscope stand with Lyostat 3 Freeze-drying stage 3MV- Likam G16. 3 16. 3mm sample holder- Olympus U-TAD compensator adapter with U-TP530 530nm ink compensator- Olympus U-LH100L-3 illumination housing with TH4-200 power supply- Nitrogen D2L reservoir- Oerlikon Trivac D 2.5E vacuum pump with AF8 exhaust mist filter- Edwards LV10K adjustable leak valve- Q Imaging QICAM 12-bit .
