Burkard 1ml all glass syringes are made to conform to BS tolerances for most laboratory applications. The plunger and barrel are individually fitted and are marked accordingly. Luer fitting is standard on all syringes.
The new Series 'C' micrometer unit will accept 1ml and 10ml syringes with single screw fixing. An attractively styled light alloy cover tube ensures complete rigidity between syringe and micrometer spindle. Reversible, single pivot mounting for right and left hand operation enables the unit to be clamped in any desired position. Delivery range from 0.2 microlitre per division
|2. Hand microapplicator
The variable drop size microapplicator is fitted with an all-glass 1ml Burkard syringe, luer fitting, and drop size is selected by sliding a single selector control knob. Drop sizes available are 0.25, 0.5, 1, 2 & 5 Ál. Constructed of non-ferrous material with components either hard anodised or electroplated in satin chrome finish, the applicator is mounted such that it can be clamped in any position during use. The 10 ml syringe and adaptor may be used to provide drop sizes up to 50 Ál
|3. Automatic microapplicator
An automatic low voltage syringe having drop sizes from 0.1 to 10 Ál in ten equal steps using the Burkard 1ml all glass syringe. The range of 1.0 Ál - 10 Ál is achieved using a 10 ml syringe and adaptor and each volume may be rapidly selected from a control lever on the front of the instrument. The microapplicator may be used in any position using a foot or ring and finger switch.
|4. Precision microapplicator
An electronically controlled low voltage microapplicator with variable drop sizes from 1 to 100 microlitres using the Burkard 1 ml all glass syringe. Alternative syringes are available to increase deliveries x 10. The unit is computer compatible and can be operated from foot, hand or remote switching. Designed with rapid traverse of the syringe in both directions. All metal construction for long term high precision dispensing. Fast selection of deliveries by thumb wheel in 0.1 Ál increments.
|5. Kearns & March knockdown
For evaluating fly sprays based on the technique described in Soap and Sanitary Chemicals (Feb 1943) Vol. 19 p 101-104, 128 with certain modifications. The dosage for mortality tests is 0.2 ml per sprayer (total 0.4 ml). The percentage mortality obtained with the official test insecticide at a dosage of 0.4 ml should be between 30 per cent and 55 per cent. Under different conditions of fly breeding and testing it might be necessary to vary the dosage in order to obtain kills within this range.
|6. Computer controlled spraying
This apparatus was designed to meet the more exacting requirements of the modern toxicology labs, but is equally suitable for most laboratory spray application requirements. Sprays may be accurately applied to a wide range of target shapes and sizes as defined by the computer programme selected. Tests with aqueous media, sprayed onto 9 cm petri dishes, showed good replication of the deposit with over 90 per cent reaching the target. The apparatus may be used in a standard fume cupboard or an external exhaust system could be fitted.
|7. Potter spray tower
A laboratory spraying apparatus designed to give an even deposit of spray over a circular area 9 cm in diameter. Suitable for studying the biological effects of chemicals both when applied as a direct spray on the organisms or as a residual film. This design incorporates more recent developments from Rothamsted Experimental Station, Harpenden, Herts, England, including the following: quickly detached atomisers, pneumatically operated spray table and all air controls mounted on attached instrument panels. A 4 inch 0-2 Bar (0-30) pressure gauge is fitted as standard equipment.
