Multi Crystal LB 2111
The gamma counter Multi Crystal LB 2111 is a compact, robust and easy-to-use instrument that has been optimized for IRMA and RIA immunoassays based on gamma-emitting isotopes like 125I, 57Co, 59Fe, 51Cr and 99Tc. Thick lead shielding efficiently prevents crosstalk between samples.
The gamma counter can be operated in a stand-alone mode or it can be hooked to a personal computer. The Multi Crystal LB 2111 is available as a 12 detector unit. To increase throughput a second detector block may be added resulting in a 24 detector instrument.
RIA and IRMA immunoassays mainly with 125I:
- Thyroid hormones (T3, T4, TSH...).
- Reproductive hormones (LH, estriol, FSH, progesterone, testosterone).
- Drug abuse screening (THC, cocaine, amphetamine).
- Allergy (histamines, IgE).
- Vitamins (e.g. vitamin D).
- Neurotransmitter (serotonin, dopamine...).
- ...and many others.
Other applications with gamma-emitting isotopes:
- Infectious diseases (e.g. hepatitis).
- Cytotoxicity based on 51Cr release.
- Kidney clearance with 99Tc.
- Receptor binding.
- Iron metabolism with 59Fe.
High Throughput with 12 or 24 detectors
- Sample throughput is high as 12 tubes.
- Extended model for 24 tubes.
- 200 samples can be measured within 17 min (1 min counting time/sample).
- Made of high-quality NaI well-type crystal providing.
- Best measurement geometry for gamma emitters.
- Energy range up to 500 KeV - suitable for the common gamma-emitting isotopes, e.g. 125I, 57Co, 59Fe, 51Cr and 99Tc.
Lead Shielding for low crosstalk
- Thick lead shielding (6 mm) around each of the detectors (12 mm total between detectors).
- Efficiently prevents crosstalk between samples.
- Sample racks facilitate loading of 12 samples at a time in a convenient way.
- With multiple racks all samples can be prepared in advance.
- In case a tube is contaminated, contamination stays in the rack and is never carried on to the instrument.
