Accessories

for attoDRY1000/2100

Replacement kit for the molecular sieve adsorber, recommended every 20,000 hours.

for attoDRY1000

Two multipurpose input channels, two configurable PID control loops & flexible remote interfaces include IEEE-488.2(GPIB) and USB.

for attoDRY1000/2100

This pumping kit comprises all necessary vacuum parts to operate the attoDRY1000/2100, and directly connects to the vacuum port of the cryostat. Included components and key features: turbomolecular pump incl. dry diaphragm backing pump (pumping speed for N2 35-67 l/s, ultimate pressure 10-7 mbar), full range pressure gauge, valve, overpressure valve, 1 m long stainless steel hose, needle valve and rubber bladder for dosing the exchange gas and all necessary KF fittings.

for VTI

This pumping kit comprises all necessary parts to operate the variable temperature insert (VTI) of any attoLIQUID2000, and thus to enable temperature control over a wide range of temperatures (1.8 .. 300 K) in conjunction with the heater and temperature sensor at the sample location, and an appropriate temperature controller. Included components and key features: rotary pump (pumping speed 22.5 m3/h, ultimate pressure 0.5 mbar), valve, overpressure valve, 5 m long PVC hose, 1 m long stainless steel hose, all necessary KF fittings.

for vacuum tube

This pumping kit comprises all necessary parts to prepare any of the attoMICROSCOPES for cooldown. This is usually done by evacuating the vacuum tube incl. the microscope to a low pressure (e.g. 10-5 mbar or lower), and then adding about 0-50 mbar of helium exchange gas to the volume. This enables conveniently cooling and warming up of the microscope without condensation on neither the positioners/scanners nor on the sample. Included components and key features: turbomolecular pump incl. dry diaphragm backing pump (pumping speed for N2 35-67 l/s, ultimate pressure 10-7 mbar), full range pressure gauge, valve, overpressure valve, 1 m long stainless steel hose, needle valve and rubber bladder for dosing the exchange gas and all necessary KF fittings.

for T < 2K

This pumping kit comprises all necessary parts to operate any attoLIQUID1000 at temperatures below 4.2 K by reducing the vapor pressure above the helium bath. Included components and key features: rotary vane pump (Pumping speed 54 m3/h, ultimate pressure 0.5 mbar), valve, overpressure valve, 2x 5 m PVC hose and all necessary KF fittings.
