Normalab 13860 Manual Houillon Viscosity Bath, 4 Tubes
Description
A compact thermostatic bath for quick manual viscosity checks
The Normalab 13860 manual Houillon viscosity bath is a 10 litre thermostatic bath designed for fast manual kinematic viscosity measurement with Houillon tubes. Up to four tubes can be tested at the same time, which makes it useful in lubricant, fuel and used-oil laboratories that need a quick answer on viscosity without a full automatic viscometer.
Normalab states that the instrument is in correlation with ASTM D7279 and D2270 and associated methods. The scope given in the leaflet is the kinematic viscosity of transparent and opaque liquids such as base oils, formulated oils, diesel oil, biodiesel and biodiesel blends, residual fuel oils, marine fuels and used lubricating oils, measured with a Houillon viscometer.

Delivered items and options
The bath is delivered ready to use with a thermostatic head, four ejectors, a power cable, the 10 litre bath and a drip tray. Houillon tubes are not delivered with the bath and are ordered separately; the leaflet refers to Normalab’s glassware catalogue for them.
Options listed are a digital temperature probe with certificate, silicone oil, a micropipette and a vacuum pump kit. The vacuum connection helps draw the sample into the Houillon tube, and the integrated drip tray keeps spills away from the bench. Low-voltage LED lighting is chosen because it stays safe if fluid splashes.
When to choose a manual Houillon bath
A manual bath fits laboratories that run small numbers of samples, field and workshop laboratories checking in-service oil, and teams that want a low-cost second viscosity station next to an automatic instrument. The 30 to 100 °C range covers the usual 40 °C and 100 °C lubricant test temperatures, although the exact temperature and tube constants must follow the method you work to.
Houillon tubes need careful cleaning and drying between samples, and the tube constant is part of the viscosity calculation, so keep the tube records with the bath. The indexer places the tubes consistently, and the ejectors mean a tube can be exchanged during a run without lowering the bath level. Before ordering, confirm the Houillon tube sizes, the bath fluid, the vacuum pump kit, a certified digital probe, and a supply with two outlets at 230 V. Related Normalab equipment is grouped under liquid analytical systems.

About brand
Normalab designs and manufactures laboratory test instruments and laboratory glassware for petroleum products at its site in Valliquerville, France. Seven Star LLC, an independent supplier in Oman, lists Normalab spare parts: the 60606 circulation pump for the coolant circuit of the NDI 450 automatic distillation analyzer, and the 60448 thermal detection thermocouple. We source Normalab parts by their five-digit reference number.
Normalab instrument families
The manufacturer arranges its instruments by the property tested: flammability, volatility, viscosity, cold flow properties, cleanliness and purity, lubricants, and bitumen, wax and grease. Its glassware line supports the same tests. The methods referenced are ASTM, ISO and IP. Refinery and fuel quality laboratories in the GCC run these instruments daily, which is why the usual request is for a replacement part rather than a complete instrument.
Ordering Normalab parts: what we need
Send the Normalab reference number of the part, the instrument model and its serial number, and a photo of the instrument nameplate. Where the part is a sensor or pump, a photo of the old item with its connector helps the manufacturer confirm the version fitted to your serial number. If you need a complete instrument, name the test method and the products you test.
